Summary: The study identified 71 transcription factors coexpressed with SSP genes in the endosperm of T. urartu, with TuNAC77 and TaNAC77 enhancing SSP gene transcription by binding to cis-elements in promoters. Knocking down TaNAC77 in common wheat resulted in a 24% reduction in total SSPs. This is the first genome-wide identification of transcriptional regulators of SSP genes in wheat.

Summary: Seed vigor is an important trait in wheat breeding, and this study identified multiple quantitative trait loci (QTLs) associated with various seed vigor traits in a doubled haploid population derived from a cross between Yangmai 16 and Zhongmai 895. The QTLs were located on chromosomes 2B, 3D, 4B, 4D, 5A, 5B, 6A, 6B, 6D, 7A, and 7D, explaining significant portions of the phenotypic variances. The study also developed KASP markers for a QTL cluster on chromosome 4D and validated them in a panel of wheat accessions. These findings provide valuable genetic resources for improving seed vigor in wheat breeding programs.

Summary: This study identified four QTL associated with PHS resistance in wheat, providing valuable genetic resources and breeding tools. Development of KASP markers and validation of their effectiveness in a test panel of cultivars offer new approaches for marker-assisted selection in wheat breeding.

Summary: A novel NAC family transcription factor TuSPR from Triticum urartu was found to negatively regulate SSP synthesis in common wheat, potentially providing a target for genetic engineering to manipulate SSP content. Knocking down the transcription factor TaSPR in common wheat resulted in increased total SSPs, indicating a conserved function with TuSPR in suppressing SSP synthesis.

Summary: This study investigates the molecular mechanisms involved in seed germination under short episodes of heat stress during the wheat grain filling stage. The expression levels of genes related to ABA, GA, and ETH were found to be significantly different under heat stress conditions. The study also highlights the role of temperature in regulating seed germination, with temperatures above 28 degrees Celsius repressing ABA-related gene expression and promoting germination.

Summary: Fungal plant infections lead to significant losses in agriculture. The antifungal agent M451 showed promise as a seed dressing for wheat seeds, effectively targeting the devastating plant fungal pathogen Fusarium spp. without negatively affecting wheat grain and seedling characteristics.

Summary: This study investigated the physiological responses of wheat and maize seedlings to exogenous auxin-type compounds. The results showed that PEG treatment inhibited seedlings growth and caused crop-specific alterations in antioxidant defence. Moreover, the application of TA-12 and TA-14 increased growth parameters and enzyme activity, and improved the growth of PEG-treated plants. The findings suggest that the preliminary application of TA-12 and TA-14 can reduce the adverse effects of moderate water deficit.

Summary: The genetic base of wheat glume stomata is not fully understood. This study mapped quantitative trait loci (QTLs) for stomatal traits onto a high-density genetic linkage map of a doubled haploid (DH) population. A total of 61 QTLs were mapped onto 16 chromosomes, and two QTL hotspots were detected. Additionally, five candidate genes were identified, which may play a role in the response of wheat glume stomata to abiotic stresses.

Summary: The genetic architecture of resistance to spot blotch in wheat was investigated through a Genome-Wide Association Study (GWAS) involving 303 diverse genotypes. The study evaluated the association panel at two different locations in India and recorded phenotypic data for two consecutive years. After analysis, seven important marker-trait associations were identified for marker-assisted selection.

Summary: The study found that seed pretreatment with calcium chloride extended aphid development time, reduced aphid population size, and improved plant resistance against wheat aphid attack by increasing Ca2+ concentration in wheat leaves and upregulating expression levels of certain genes related to defense responses. Callose concentration in the leaves of plants grown from CaCl2-pretreated seeds increased significantly upon aphid attack, with callose deposition mainly observed in the phloem.
