Identification of the Colletotrichum species associated with mango diseases and a universal LAMP detection method for C. gloeosporioides species complex

The Colletotrichum gloeosporioides species complex contains plant pathogens linked to Anthracnose diseases afflicting various crops. In this study, we designed a loop-mediated isothermal amplification assay (LAMP) primer set based on calmodulin gene coding region sequences from taxonomically authorized isolates of species from this complex to rapidly detect the presence of fungi associated with Anthracnose diseases. This test can be employed at any point between cultivation and sale. Moreover, we examined the specificity and detectable range of this primer set using isolates selected from species of the genus Colletotrichum. This test was able to specifically detect members of the C. gloeosporioides species complex, including C. gloeosporioides, C. aotearoa, C. fructicola, C. horii, C. kahawae, C. musae, C. siamense, C. theobromicola, and C. tropicale. Key Words: Anthracnose, diagnosis, phylogeny, plant disease

New locations and distribution of the alien species Acalipha australis L. (Euforbiaceae) in Azerbaijan

The article is devoted to the introduced species Acalypha australis L., which has recently been actively expanding its secondary range in Azerbaijan. The results of the study of the distribution and new localities of the species in the republic are discussed, the areas are specified, the species composition of phytocenoses is described, the influence of field moisture on the vitality of A. australis and the dependence on vertical zoning are considered. The main habitats of the species are garden plots, vegetable gardens, park zones and the sides of small water channels, the introduction of A. australis into forest, coastal ecosystems is noted.

New records on edible mushrooms collected from Guba district

The study presents first information on edible mushrooms of Guba district. Specimens were collected in 2017-19 in forest ecosystem. As a result of the study, 17 species (Amanita rubescens, Boletus edulis, B. reticulatus, Cerioporus squamosus, Clitocybe odora, Clitopilus prunulus, Coprinellus micaceus, Hortiboletus rubellus, Laetiporus sulphureus, Leccinellum pseudoscabrum, Legaliana badia, Lycoperdon perlatum, Macrolepiota mastoidea, M. procera, Russula risigallina, R. turci, Xerocomellus chrysenteron) of edible mushrooms belonging to 14 genera were identified. Legaliana badia is a new record for Azerbaijan mycobiota. All other mushroom species are new records for the study area. GPS coordinates and ecological groups of mushrooms were identified.
