Genetic variability and populations, structure were studied in 15 geographical populations of Geranium purpureum Vill. (Geraniaceae). Genetic diversity parameters were determined in these populations. AMOVA and Gst analyses revealed the presence of genetic variability within populations and significant molecular difference among the studied populations. Mantel test showed positive significant correlation between genetic distance and geographical distance of the studied populations. STRUCTURE and K-Means clustering revealed populations, genetic stratification. UPGMA dendrogram of populations based on morphological characters was in agreement with NJ tree of molecular data. These results indicated that geographical populations of G. purpureum are well differentiated both in genetic content as well as morphological characteristics. Consensus tree based on morphological and genetic data separated some of these populations from the others suggesting the existence of ecotypes within this species.

Erodium (Geranaiceae) species are distributed in different habitats of Iran. Some species are of medicinal importance while some are well known weeds. In arid and semi-arid regions, E. cicutarium has had some importance as a forage plant and is an important grazing plant and source of protein supplements to straw for ruminants in semi deserts and wastelands of the Middle East. There is no information on its population genetic structure, genetic diversity, and morphological variability in Iran. Due to the medicinal importance of this species, a genetic variability and populations? structure study is performed studying 15 geographical populations of E. cicutarium Therefore, we used six inter-retrotransposon amplified polymorphism (IRAP) markers and 15 combined IRAP markers to reveal within and among population genetic diversity in this plant. AMOVA test produced significant genetic difference (PhiPT = 0.39, P = 0.010) among the studied populations and also revealed that, 55% of total genetic variability was due to within population diversity while, 45% was due to among population genetic differentiation. Mantel test showed positive significant correlation between genetic distance and geographical distance of the studied populations. Networking, STRUCTURE analyses and population assignment test revealed some degree of gene flow among these populations. PCoA plot of populations based on morphological characters was in agreement with MDS plot of molecular data. These results indicated that geographical populations of E. cicutarium are well differentiated both in genetic content as well as morphological characteristics. Consensus tree based on morphological and genetic data separated some of these populations from the others suggesting the existence of ecotypes within this species.

Abstract. Azimishad F, Sheidai M, Talebi SM, Noormohammadi Z. 2019. Species relationship and genetic diversity in some Iranian Lamium L. species using ISSR markers. Biodiversitas 20: 1963-1972. Lamium is a widespread and taxonomically complex genus of Lamiaceae which comprises of 16-38 species. This genus is represented in Iran by nine species. In the present study, we used morphological and molecular (ISSR, Cp DNA, and nrITS) data to evaluate species relationships, genetic diversity and population genetic structure of the genus. 27 morphological characteristics, including 13 qualitative and 14 quantitative, and ten ISSR markers were used for morphological and genetical evaluation of 73 accessions from eight taxa. In general, species relationships obtained from morphological and molecular data were largely congruent. In the morphological study, characteristics like the life form, leaf shape, absence/existence of bracts and shape of corolla, were distinctive traits and we did not encounter intermediate forms. Our findings indicated a very high efficiency of the ISSR markers in the identification and delimitation of Lamium species. These results confirmed the placement of L. galeobdolon in the genus Lamium and segregation of L. purpureum and L. garganicum in section Lamium. AMOVA analysis revealed that the species of this genus are genetically differentiated. Nm analysis showed very low value of gene flow among the studied species and mantel test indicated isolation by distance occurred among them.

Tanzania has been growing avocado for decades. A wide variability of the avocado germplasm has been found, and the crop is largely contributing to the earnings of the farmers, traders, and the government, but its genetic diversity is scantly investigated. With the purpose of comparing morphological and genetic characteristics of this germplasm and uncovering the correlation between them and the geographical location, 226 adult seedling avocado trees were sampled in southwestern Tanzania. Their morphological characters were recorded, and their genetic diversity was evaluated based on 10 microsatellite loci. Discriminant analysis of principal components showed that the germplasm studied consisted of four genetic clusters that had an overall average gene diversity of 0.59 and 15.9% molecular variation among them. Most of the phenotypes were common in at least two clusters. The genetic clusters were also portrayed by multivariate analysis and hierarchical clustering for the molecular data but not for the morphology data. Using the Mantel test, a weak significant correlation was found between the genetic, morphological, and geographical distances, which indicates that the genetic variation present in the material is weakly reflected by the observed phenotypic variation and that both measures of variation varied slightly with the geographical sampling locations.

Abstract. Makmur K, Chikmawati T, Sobir. 2020. Genetic variability of lemon basil (Ocimum × africanum Lour.) from Indonesia based on morphological characters and ISSR markers. Biodiversitas 21: 5948-5953. Lemon basil (Ocimum × africanum Lour.) or kemangi is a highly beneficial plant, yet still underutilized. Therefore, providing necessary information on genetic diversity of this species is essential for further utilization. The aim of this study was to elucidate genetic diversity of 33 accessions of O. × africanum collected from four Islands of Indonesia along with three accessions of Ocimum basilicum L. Morphological observation was conducted on 37 morphological characters following the International Union for the Protection of New Varieties of Plants descriptor guidelines; subsequently, 13 ISSR primers were employed in molecular analysis. Both morphological and molecular data were analyzed based on simple matching similarity index using UPGMA method. Morphologically, O. × africanum and O. basilicum were clearly separated at the similarity index of 0.52, and among two species were divided into two groups according to two either character. ISSR analysis using 13 ISSR primers produced 111 DNA bands, and 108 of them (97.29%) were polymorphic. Cluster analysis based on ISSR data could not explicitly separate O. × africanum and O. basilicum accessions. Besides, Ocimum accessions collected from the same area did not always cluster into one group.

Stellaria media (L.) Vill., known under the name of chickweed, is an annual medicinal plant in the family Caryophyllaceae. This species is distributed in the north regions of Iran. In the present study, the Random Amplified Polymorphic DNA (RAPD) technique was used to estimate infraspecific variation in different populations of Stellaria media. Samples from 11 populations were collected from different regions of the country during spring 2018. For RAPD investigations, populations were divided into three geographical regions. This study provides important data on the genetic diversity, population structure and morphological characteristics of Stellaria media. The AMOVA and Gst analyses showed that the populations of this species are genetically differentiated. Nm analysis revealed very low value of genetic diversity among the studied population and mantel test indicated isolation by distance occurred among them. The studied populations of S. media are differentiated in morphological characteristics and genetic content. Bangladesh J. Plant Taxon. 27(1): 173-184, 2020 (June)

AbstractThe present study aimed to reveal genetic diversity and population structure in three Onosma species i.e., Onosma bulbotrichum DC., O. elwendicum Wettst. and O. sericeum Willd. (Boraginaceae) growing in Iran. This study was performed to check if the ISSR molecular markers could be used in the Onosma species delimitation. We also investigated the infra-specific morphological variability and if we can identify infra-species taxonomic forms. The present study revealed within species genetic and morphological diversity. ISSR data could delimit the studied species as they were separated from each other in NJ tree, maximum parsimony and STRUCTURE analysis. AMOVA and Hickory tests produced significant genetic difference among the studied species. The Mantel test showed no correlation between genetic distance and geographical distance of the populations for all three species. Reticulation analysis and Nm estimation showed gene flow among these populations. We could identify a few ISSR loci that are adaptive. Data obtained can be used in conservation of these medicinal plants in Iran.

Senecio vulgaris L., an annual herb belonging to the Asteraceae, is widely distributed in different regions of the world. There is no information on the intraspecific variations of the morphological and molecular features of this species. In the present investigation, we studied the morphological and genetic diversity of 81 accessions of S. vulgaris collected from 10 geographical populations. Eleven inter simple sequence repeat (ISSR) primers were used for the examination of genetic variations among the populations. Analysis of molecular variance (AMOVA) and GST analyses revealed significant differences among the investigated populations. A significant correlation between genetic distance and geographical distance was revealed by the Mantel test. However, reticulation analysis indicated the occurrence of gene flow among most of the populations studied. Principal component analysis (PCA) plot showed that the number of capitula, length of the cauline leaf and plant height were the most variable morphological characters. Principal coordinates analysis (PCoA) plot revealed two groups of populations, according to molecular and morphological data. The results suggested the existence of possible intraspecific taxonomic ranks within this species.

Brown algae of the genus Cystoseira sensu lato form the most diverse and productive marine ecosystems throughout the Mediterranean Sea and have equal roles also in the Black Sea where they have been decreasing in the recent years. The taxonomy of Cystoseira s.l. taxa from the Black Sea is still not well understood, and questions arise when related taxa have to be delimited. In addition to morphological descriptions, this study provides for the first time molecular data of the Black Sea Cystoseira s.l. distinct morphologies as an additional tool to clarify their identities and phylogenetic affinities. The analysis of two mitochondrial markers (cytochrome oxidase subunit 1—COI, and 23S-tRNAVal intergenic spacer—mt-spacer) showed that Cystoseira s.l. specimens from the Black Sea belong to two recently resurrected genera, namely Gongolaria and Ericaria. Molecular data confirm the morphological identification of G. barbata, which is characterized by high morphological plasticity in the Black Sea. The morphological data presented in this study support the transition of G. barbata to the genus Gongolaria, which was previously proposed based solely on genetic data. For the Black Sea endemic taxon C. bosphorica, sequence divergence suggests conspecificity with Mediterranean Sea species E. crinita and E. barbatula. However, considering original morphological characteristics of the taxon, its geographical isolation, and endemism, the new combination Ericaria crinita f. bosphorica comb. nov. is proposed.

Morphological And Molecular Data

Several collections of Amanita species from section Vaginatae have been reported to be strictly associated with Helianthemum plants growing in grasslands, a still largely under-explored ectomycorrhizal habitat. The main aim of this study was to investigate the taxonomic status and phylogenetic position of strictly Helianthemum-associated Amanita sect. Vaginatae taxa, informally named Amanita “helianthemicola”. Collections from Italy, England and France were included in this study. The morphologically closely related species complex A. lividopallescens was also examined. Analyses were carried out based on both morphological and molecular data (phylogenetic analysis of the nrITS sequences). All investigated Amanita collections, which are strictly associated with Helianthemum nummularium, turned out to be conspecific with A. simulans. Amanita simulans was recently described from Sardinia (Italy) from Populus nigra habitats based on morphological characters only. As the holotype of A. simulans was lost, a neotype is designated here based on a voucher from the original collecting area. Amanita simulans is re-described, and an extensive discussion on the morphological variability, host species range, distribution and related taxa is provided. Amanita lividopallescens was confirmed as a good species, and re-delimited based on our phylogenetic analysis; moreover, it was epitypified with a recent and well-documented collection from Corse (France). Amanita stenospora is a synonym of A. lividopallescens, being a colour form of the latter without taxonomic value.
