The investigation of dehydrins participation in MeJA-induced protection of wheat plants (Triticum aestivum L.) from drought stress was performed. The dehydration was designed by the presence of mannitol in increasing concentration (3, 4, and 5%) in the growth medium of wheat seedlings. Pre-treatment of 3-days-old seedlings with 0.1 μM MeJA reduced the level of drought-induced growth retardation as well as membrane structures lesions. Exogenous MeJA enhanced accumulation of the TADHN dehydrin transcripts and dehydrin proteins with Mw 28 and 55 kDa in wheat seedlings under normal conditions and additionally increased their expression during dehydration. The obtained data may indicate the dehydrins involvement in MeJA protective effect on wheat plants from the damages caused by water deficit.

Wheat is an important cereal crop globally and in the United States, and is the largest crop grown by acreage in Colorado. In June 2023, we observed wheat fields displaying severe yellowing and virus-like disease symptoms in plants across seven eastern Colorado counties (Yuma, Prowers, Kit Carson, Washington, Sedgewick, Morgan, and Weld). Symptomatic plants were prominent in fields and appeared bright yellow, with ringspots, mosaic patterning, and streaking on leaves.

Wheat stripe rust, caused by f. sp. (), poses a significant threat to wheat production, particularly in Henan province, which produces more than 36 million tons of wheat grain every year, the highest production among all provinces in China.

Allohexaploid wheat (Triticum aestivum L.) is one of the major crops worldwide, however there is very limited research on the transcriptional programmes of underlying cell type specification. Single-cell RNA sequencing (scRNA-seq) was used to unravel the transcriptome heterogeneity of cells and the composition of cell types in broad-spectrum organisms.

Background: Improving the germination performance of bread wheat is an important breeding target in many wheat-growing countries where seedlings are often established in soils with high salinity levels. This study sought to characterize the molecular mechanisms underlying germination performance in salt-stressed wheat. To achieve this goal, a genome-wide association study (GWAS) was performed on 292 Iranian bread wheat accessions, including 202 landraces and 90 cultivars.

Global climate change leads to the increased occurrence of environmental stress (including drought and heat stress) during the vegetative and reproductive stages of cereal crop development. Thus, more attention should be given to developing new cereal cultivars with improved tolerance to environmental stress. However, during the development of new stress-tolerant cereal cultivars, the balance between improved stress responses (which occur at the expense of growth) and plant yield needs to be maintained.
