- ... Wild Triticum and Aegilops species are increasingly used in wheat breeding programmes around the world as donors of genes conferring resistance to biotic and abiotic stresses, as well as of genes that contribute to the improvement of grain quality. In the present study, thirty-nine accessions of diploid species with the A genome (Triticum boeoticum and T. urartu) were evaluated for the presence of ...

- ... ERF transcription factors play important roles in regulating gene expression under abiotic and biotic stresses. The first member of the ERF gene family in wheat (Triticum aestivum L.) was isolated by screening a drought-induced cDNA library and designated as T. aestivum ethylene-responsive factor 1 (TaERF1), which encoded a putative protein of 355 amino acids with a conserved DNA-binding domain an ...

- ... Populations of winter barley were sown in autumn in large tubs of soil to half of which additional phosphate was supplied. Half the plants of each phosphate treatment were infected with powdery mildew (Erysiphe graminis D.C. f. sp. hordei Marchal) and all plants were transferred to the-field. Infection induced extensive leaf injury during mid-winter in plants at low phosphate, but injury was great ...
