Abstract:
... This work presents the biochemical, cytochemical and molecular studies on two groups of PR proteins, β-1,3-glucanases and chitinases, and the arabinogalactan proteins (AGP) during the early stages of androgenesis induction in two breeding lines of rye (Secale cereale L.) with different androgenic potential. The process of androgenesis was initiated by tillers pre-treatments with low temperature, m ...

Abstract:
... The Waxy (Wx) gene that governs amylose synthesis is an old but widely used target in improving the quality of starchy crops. New genome-editing strategies are being deployed to create beneficial Wx alleles with finely tuned amylose content (AC). Precise targeting must be combined with traditional approaches to develop healthier and high-quality breeding lines. ...

Previously, we cloned a PHS resistance gene, TaPHS1, and identified two causal mutations for reduced seed dormancy (SD) and increased PHS susceptibility. Here we identified a novel allelic variation of C to T transition in 3′-UTR of TaPHS1, which associated with reduced SD and PHS resistance. The T allele o ...

Abstract:
... Lodging is a complex phenomenon affecting wheat production worldwide and is a consequence of the interaction of wheat plants with abiotic (wind, rain, etc.) and biotic (e. g. plant disease, etc.) factors. Wheat breeders rely heavily on incidences of natural lodging to select lines with resistance; however, the intermittent nature of lodging events means this approach is unreliable. A model of the ...
