AbstractHelichrysum oocephalum is a medicinal plant of the genus Helichrysum that have limited distribution in Iran. Local geographical populations may differ in their genetic content and form different gene pools. Therefore, we carried out population genetic investigation and morphological studies in five geographical populations of Helichrysum oocephalum by using ISSR molecular markers. AMOVA produced the significant genetic differences. The mean Nm value revealed some degree of gene flow among Helichrysum oocephalum 8. Molecular and morphological analysis indicated that we have 2 groups in the studied populations. The present findings may be of use in the conservation of this medicinal plant in Iran.

Stachys lavandulifolia Vahl. (Lamiaceae) is an important medicinal plant that grows in different parts of Iran and forms many geographical populations. We have no information on its population genetic structure, genetic diversity, and morphological variability in Iran. Therefore, we planned a genetic and morphological investigation in St. lavandulifolia geographical populations in Iran. The obtained data are important for conservation and germplasm management of this medicinal plant species. Seventy-four plants were randomly collected from 14 geographical populations and studied for genetic diversity (ISSR molecular markers) and morphological variability. The  highest value for gene diversity occurred in populations 1 and 4 (0.133 and 0.129, respectively). The  latitude and altitude were positively correlated with gene diversity and genetic polymorphism while longitude was negatively correlated with them. The Mantel test showed correlation between genetic distance and geographical distance. AMOVA revealed a significant genetic difference among populations and showed that 58% of total genetic variation was due to within-population diversity. The STRUCTURE analysis and K-Means clustering identified two gene pools for St. lavandulifolia. The  consensus tree of both molecular and morphological data identified divergent populations.

Abstract Lallemantia royleana (Benth.) Benth. (Family Lamiaceae), is one of the most popular medicinal plants in Iran. It is an herbaceous pant that is commonly known as “Lady mantle”. The vernacular name of Lallemantia royleana’s seed is Balangu or Balangu Shirazi that is used as a source of medicine. Medicinal plants are very important from economic point of view in Iran and several large industries are focused on medicinal plants cultivation, extraction and export. Therefore, providing data on the biology of these plants is important for the country. Lallemantia royleana grows in different parts of Iran and forms several local populations. Genetic, morphological and biochemical divergence of geographical populations are well known in plant species. We have no report on population genetic structure, genetic fragmentation, local adaptation and gen flow of Lallemantia royleana populations in the country. Therefore, the present population genetics investigation was programmed to produce data on above said questions. Randomly collected plants of 7 geographical regions were studied by ISSR molecular markers. This information can be used in hybridization and gene conservation of this medicinal plant in Iran.

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.

Persian hogweed (Heracleum persicum Desf. ex Fischer) is native to Iran but was introduced to Europe as an invasive plant. It has medicinal and edible values. Its fruits have been used to relieve flatulence, stomach aches as well as a flavoring as a digestive and an antiseptic. This medicinal plant forms many geographical populations in the country, particularly in mountainous regions; however, we have no data on the genetic structure and genetic diversity of this plant species. Such information can be used in gene pool identification and future genetic conservation and breeding programs. Therefore, the present study was performed with the following aims: 1- Provide data on genetic diversity of geographical populations, 2- Identify the potential gene pools for future genetic conservation and breeding programs. We used both Inter-simple sequence repeats (ISSR) and the Start Codon Targeted (SCoT) molecular markers as these are suitable molecular markers for genetic diversity investigations. There are highly polymorphic, reproducible, and relatively low cost markers. The present study revealed that both ISSR and SCoT markers produce data on the genetic variability and genetic affinity of the local populations. Both molecular markers revealed a good level of genetic variability within and among Heracleum persicum populations. Analysis of molecular variance (AMOVA) produced a significant differences between geographical populations for both markers. We could identify few ISSR as well as SCoT bands which can differentiate the studied populations. The moderate to a good level of genetic diversity we observed within each H. persicum may be due to cross pollination. In conclusion, we suggest using combination of ISSR and SCoT molecular markers to study population genetic variability in H. persicum geographical populations for future genetic conservation and germplasm collection of this medicinal plant.

Abstract Introduction Endoscopic skull base approaches are broadly used in modern neurosurgery. The support of neuronavigation can help to effectively target the lesion avoiding complications. In children, endoscopic-assisted skull base surgery in combination with navigation systems becomes even more important because of the morphological variability and rare diseases affecting the sellar and parasellar regions. This paper aims to analyze our first experience on augmented reality navigation in endoscopic skull base surgery in a pediatric case series. Patients and methods A retrospective review identified seventeen endoscopic-assisted endonasal or transoral procedures performed in an interdisciplinary setting in a period between October 2011 and May 2020. In all the cases, the surgical target was a lesion in the sellar or parasellar region. Clinical conditions, MRI appearance, intraoperative conditions, postoperative MRI, possible complications, and outcomes were analyzed. Results The mean age of our patients was 14.5 ± 2.4 years. The diagnosis varied, but craniopharyngiomas (31.2%) were mostly represented. AR navigation was experienced to be very helpful for effectively targeting the lesion and defining the intraoperative extension of the pathology. In 65% of the oncologic cases, a radical removal was proven in postoperative MRI. The mean follow-up was 89 ± 79 months. There were no deaths in our series. No long-term complications were registered; two cerebrospinal fluid (CSF) fistulas and a secondary abscess required further surgery. Conclusion The implementation of augmented reality to endoscopic-assisted neuronavigated procedures within the skull base was feasible and did provide relevant information directly in the endoscopic field of view and was experienced to be useful in the pediatric cases, where anatomical variability and rarity of the pathologies make surgery more challenging.

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.

Helichrysum armenium and H. rubicundum are two medicinally important plants of Iran that are distributed in various regions of the country. They are extensively used by locals as medicinal plants and a great negative selection pressure is applied on them. Therefore, due to importance of these plant species, we performed a population genetic study in both species. For this study, we used 66 randomly collected plants from 24 geographical populations of Helichrysum armenium and H. rubicundu. These species had areas of overlap and contact and we found some intermediate plants that were included in our study too. UPGMA and MDS analyses revealed morphological separation of these closely related species and placed intermediate plants in an intermediate position. ISSR analysis revealed inter-population genetic diversity and K-Means clustering and STRUCTURE analyses revealed populations. Genetic stratification in both species. Genetic difference of the studied populations was not correlated to geographical distance. Triangle plot of Bayesian analysis and NeighborNet plot showed inter-specific gene flow. The studied populations showed plants with 2n = 2x = 14 and 2n = 4x = 28 chromosomes and differed significantly in their meiotic behavior. Therefore, a combination of genetic stratification, and genetic admixture as well as polyploidy and chromosomes structural changes, have played rule in Helichrysum diversification.

Abstract. Rini MV, Yelli F, Tambunan DL, Damayanti I. 2021. Morphological and molecular identifications of three native arbuscular mycorrhizal fungi isolated from the rhizosphere of Elaeis guineensis and Jatropha curcas in Indonesia. Biodiversitas 22: 4940-4947. Molecular analysis has been widely used to provide more accurate identification within arbuscular mycorrhizal fungi (AMF) species than identification based on morphology. However, morphological analysis is essential for a basic preliminary of classification studies. Therefore, a study is needed to complete the identification of AMF isolates through morphological and molecular analyses. This research used three AMF isolates, namely MV 5, MV 17, and MV 18, which were isolated from Indonesian agricultural land. Spore-based taxonomy (shape, size, color, ornamentation, PVLG, and Melzer’s reaction) and fungal colonization on roots of maize trap plants were employed for the morphological studies. AMF species identification was performed using molecular analysis through nested-Polymerase Chain Reaction (PCR) to amplify a fragment of SSU rRNA followed by sequencing and phylogenetic tree construction. Morphological analysis showed that MV 5 had spores borne from the neck of the sporiferous saccule, MV 17 was found to have a bulbous suspensor without a germination shield, and MV 18 had spores borne from subtending hyphae. The SSUR rRNA analysis revealed that MV 5, MV 15, and MV 18 were identified as Acaulospora longula, Gigaspora margarita, and Glomus etunicatum, respectively. Both morphological and molecular methods demonstrated reliable and consistent results that complement AMF taxonomy studies.
