Expression of the late embryogenesis abundant (LEA) gene is usually associated with plant response to dehydration. In this study, a drought-tolerant genotype was screened from 48 accessions of Tibetan hulless barley (Hordeum vulgare ssp. vulgare). By using virus-induced gene silencing, the influence of two LEA genes (HVA1 and Dhn6) on drought tolerance of(More)
BACKGROUND Hulless barley is attracting increasing attention due to its unique nutritional value and potential health benefits. However, the molecular biology of the barley grain development and nutrient storage are not well understood. Furthermore, the genetic potential of hulless barley has not been fully tapped for breeding. METHODOLOGY/PRINCIPAL(More)
Thirty-six gene sequences encoding the gibberellin (GA) 20-oxidase were obtained from Dasypyrum villosum and its dwarf mutant. Sequence alignment showed that there were 21 SNPs and 4 InDels among these sequences which could be divided into three haplotypes—haplotype I, II, and III with 1,293, 1,297, and 1,294 bp in length, respectively. They contained a CDS(More)
Tryptophan decarboxylase (TDC), which catalyzes the conversion of Trp to tryptamine, provides a common backbone for many secondary metabolites, and is important in defending plants from abiotic stress such as pathogen infection and insect attack. In this study, we cloned two TDC genes, AeVTDC1 and AeVTDC2, from Ae. variabilis accession No. 1 with resistance(More)
One of the reasons for the progressive yield decline observed in cereals production is the rapid build-up of populations of the cereal cyst nematode (CCN, Heterodera avenae). These nematodes secrete so-call effectors into their host plant to suppress the plant defense responses, alter plant signaling pathways and then induce the formation of syncytium after(More)
Powdery mildew (Pm), caused by Blumeria graminis f. sp. tritici (Bgt), is one of the most serious diseases for common wheat in many regions around the world. Seeking for new resistance source is urgently required to meet the challenge of the rapid loss of resistance due to the co-evolution of the pathogen’s virulence. Wheat line 07jian126 (Triticum aestivum(More)
Drought is one of the major abiotic stresses restricting the yield of wheat (Triticum aestivum L.). Breeding wheat varieties with drought tolerance is an effective and durable way to fight against drought. Here we reported introduction of AtHDG11 into wheat via Agrobacterium-mediated transformation and analyzed the morphological and physiological(More)
VERNALIZATION1 (VRN1) is a central regulator of the vernalization requirement, which affects the yield and geographical distribution of Triticeae crops through regulation of the flowering time. The first intron (Intron I) of VRN1 contains putative cis-elements that mediate repression of VRN1 expression. Allelic variations in Intron I are closely associated(More)
Whether the caryopsis of barley is naked or covered is controlled by the Nud gene encoding an ethylene response factor (ERF) family transcription factor (TF) of the AP2/ERF TF superfamily that is involved in the lipid biosynthesis pathway. In covered barley, lipids on the surface of caryopses act as a glue for their tight adhesion with hulls. Separation of(More)
