Inheritance and identification of molecular markers associated with spot blotch (Cochliobolus sativus L.) resistance through microsatellites analysis in barley Genet. Mol. Biol.
Kuldeep,Tyagi; Nandan,Rajiv; Kumar,Uttam; Prasad,Lal Chand; Chand,Ramesh; Joshi,Arun Kumar.
Spot blotch resistant (IBON 18) and susceptible (RD 2508) lines were crossed to investigate inheritance of resistance and to identify simple sequence repeats (SSRs) associated with resistance. F1 resistance was intermediate and suggested additive nature of inheritance. Three additive genes was noted in the distribution of F3, F4 and F5 generations. In F6 and F6-7, the quantitative and qualitative approaches also suggested the control of three resistance genes. The parents and the RILs (F6/F6-7) were grown in four environments and spot blotch severity recorded. Forty five SSR primers, specific for chromosomes 1 (7H) and 5 (1H), were applied. Of these, 12 were polymorphic between the parents, and between the resistant and susceptible bulks. Three markers BMS...

Improvement of xylanase production by Cochliobolus sativus in solid state fermentation BJM
Bakri,Yasser; Jawhar,Mohammed; Arabi,Mohammed Imad Eddin.
The xylanase production by Cochliobolus sativus strain Cs6 was improved under solid state fermentation (SSF). High xylanase activity (1079 U/g) was obtained when wheat straw was used after 8 days of incubation. Combinations of sodium nitrate with peptone or yeast extract resulted in an increased xylanase production (1543 and 1483 U/g, respectively). The Cs6 strain grown in SSF in a simple medium, proved to be a promising microorganism for xylanase production.
