Crop wild relatives adaptively diversified for environmental stresses are valuable resources for crop breeding especially for climate change scenarios, supposedly worsening drought and heat conditions. In this study, genetic variation of 54 barley genotypes comprised of 47 H. vulgare spp. spontaneum genotypes collected from west of Iran along with Reyhan cultivar and six F1 hybrids resulted fro...
almonds belong to prunus genus, which is related to rosaceae family. it has close relatives with different species of stoned fruits. one of the main reasons for the long period of seed germination in prunus is compound dormancy, such as the external seed cover as physical dormancy and embryo dormancy causes physiological dormancy. seed stratification and treatments with various hormones are use...
Polyploidy is a common phenomenon occurring in a vast number of land plants. Investigations of patterns of inheritance and the origins of plants (i.e., autopolyploidy vs. allopolyploidy) usually involve cytogenetic and molecular studies of chromosome pairing, chromosome mapping, and marker segregation analysis through experimental crosses and progeny tests. Such studies are missing for most wil...
Extended Abstract Introduction: Capparis spinose is from Capparis genus, and Capparidaceae family includes 350 species. It is originated from Mediterranean region. Human as food uses entire parts of C. spinose as young stems, flower buds, fruit, and seed. Caper, trade name, has several species in Iran. C. spinose has a high capacity in international agriculture markets. Today, focused on Caper...
The family Hepeviridae consists of positive-stranded RNA viruses that infect a wide range of mammalian species, as well as chickens and trout. A subset of these viruses infects humans and can cause a self-limiting acute hepatitis that may become chronic in immunosuppressed individuals. Current published descriptions of the taxonomical divisions within the family Hepeviridae are contradictory in...
This review provides detailed morphological descriptions of some wild mushrooms the genus Xeromphalina, Cookeina, Gyromitra, Xylaria, Phellodon, Marasmius and Parasola, including common species for each genus.
Abstract Wild melon (Cucumis melo var. agrestis) commonly known as African melon grows in tropical and semi tropical regions of the world. It also known as a valuable medicinal plant has numerous pharmaceutical properties and is considered as a valuable germplasm in cultivated melons breeding. In the present study, genetic variation of sixteen wild melons, collected from Mazandaran provin...
The article presents the results of introducing wild species. forms and varieties Allium L. in South-Ural Botanical Garden– Institute, Ufa. This genus is known for many useful plants – edible, medicinal ornamental its rare species requiring protection. collection contains 111 taxa: 92 species, plus a number onion cultivars forms. It includes 7 listed Red Book Bashkortostan, 35 from other region...
The Pyrus species exhibit the gametophytic self -incompatibility which is considered to be the most widespread self-incompatibility system among flowering plants. This system prevents self-fertilization through a specific pollen-pistil recognition mechanism. The S-allele diversity in the Iranian genotypes indicates that the pear germplasm of Iran can be an excellent source of variability for br...
Capsicum chinense and C. frutescens peppers are part of the Brazilian biodiversity, and the Amazon basin is the area of greatest diversity for them, especially for that former species. Nevertheless, little is known about their evolutionary history. Aiming to identify genotypes with wild and domesticated characteristics, 30 accessions of the germplasm bank of Embrapa were characterized using mor...
