Article Synopsis
- The Mla locus in barley includes diverse genes that help the plant resist certain fungal pathogens through specific immune responses.
- Researchers identified a gene, Scs6, that differs from Mla genes and makes barley susceptible to the necrotrophic fungus Bipolaris sorokiniana.
- The Scs6 protein interacts with a peptide effector from the fungus to trigger cell death in barley, indicating it plays a role in disease susceptibility, and may lead to advancements in developing crops resistant to these pathogens.
Nucleotide-binding leucine-rich repeat (NLR) disease resistance genes typically confer resistance against races of a single pathogen. Here, we report that Yr87/Lr85, an NLR gene from Aegilops sharonensis and Aegilops longissima, confers resistance against both P. striiformis tritici (Pst) and Puccinia triticina (Pt) that cause stripe and leaf rust, respectively.

However, gene transfer from Aegilops has been hampered by difficulties in detecting introgressed U- and M-genome chromatin in the wheat background at high resolution. The present study applied DArTseq technology to genotype two backcrossed populations (BC382, BC642) derived from crosses of wheat line Mv9kr1 with Ae.

Gene transfer is possible via bridge genetic materials derived from intergeneric hybrids. During this process, it is essential to precisely identify the rye chromatin in the wheat genetic background.
