Mutagenesis is a well-known technique for introducing new variants into crop plants. In the present study, M2 populations were generated in cowpea (Vigna unguiculata (L.) Walp.) variety CO7 using gamma irradiation. The progeny used to investigate effectiveness of irradiation doses and examined agronomic traits. genomic variation mutants their parents was analysed five SCoT markers. Marker analy...

The Araceae family plant in the Mount Sidole has a diversity and variety of life forms. purpose this study is to describe relationship based on morphological characters. Sampling using path method (belt transect) with free collection techniques. size track used 10 m wide ± 15 km long along Mountain climbing at an altitude 400-1780 above sea level. Morphological data measurement refers 37 merist...

Powdery mildew disease of oilseed mustard caused by Erysiphe cruciferarum is a primary reason yield reduction not only in India but also throughout the world. Identification and cultivation resistant genotypes against powdery way to overcome this challenge. In present investigation, we targeted screen 75 Brassica based on indexing under field conditions gene-specific molecular markers. Disease ...

Novel cry genes are potential candidates for resistance management strategies, due to their different structures and modes of action. Therefore, it is desirable to clone and express novel cry genes from several new isolates of Bacillus thuringiensis (Bt). In the present study, 28 Bt strains were characterized at morphological and molecular level. All these strains are Gram positive, endospore f...

The population genetic structure of the periwinkle Littorina littorea was analysed using random amplified polymorphic DNA (RAPD). Three primers, coding for six putative polymorphic loci were surveyed to infer the genetic structure of seven populations located along the heavily polluted Western (i.e. in order of decreasing pollution load W1, W2, W3 and R1) and the relatively clean Eastern Scheld...

An integrated systematic study was carried out to clarify the taxonomical position and relationship of Fusarium langsethiae to other taxa within the Fusarium section Sporotrichiella. Strains of this species were compared with strains of the closely related species Fusarium poae and Fusarium sporotrichioides using a composite dataset. This set consisted of DNA sequences derived from the ribosoma...

Sponges are considered poor invaders, and no genetic studies on introduced sponges have been performed up to now. Paraleucilla magna is the first calcareous sponge introduced to the Mediterranean and Northeastern Atlantic. The study aimed at investigating the genetic makeup and connectivity of the introduced populations of P. magna and at exploring signs of local phenotypic adaptation, to gain ...

13 selected purslane accessions were subjected to five salinity levels 0, 8, 16, 24, and 32 dS m(-1). Salinity effect was evaluated on the basis of biomass yield reduction, physiological attributes, and stem-root anatomical changes. Aggravated salinity stress caused significant (P < 0.05) reduction in all measured parameters and the highest salinity showed more detrimental effect compared to co...

Genetic diversity of 50 Tunisian almond (Prunus dulcis Mill.) genotypes and their relationships to European and American cultivars were studied. In total 82 genotypes were analyzed using ten genomic SSRs. A total of 159 alleles were scored and their sizes ranged from 116 to 227 bp. The number of alleles per locus varied from 12 to 23 with an average of 15.9 alleles per locus. Mean expected and ...
