Summary: In this study, the characteristics of the durum wheat PR-1 gene family were revealed through genome-scale analysis. It was found that the PR-1 genes showed temporal and spatial specificity and were induced by different abiotic stresses. This data will contribute to the understanding of the roles of PR-1 genes in stress responses and provide insights for crop improvement.

Summary: Waterlogging significantly impacts wheat growth and development by limiting oxygen availability in the root zone, which in turn negatively affects plant metabolism. The formation of adventitious roots and root cortical aerenchyma are important adaptive traits for plants to survive in waterlogged conditions, with certain genotypes showing promising potential for breeding waterlogging-tolerant wheat varieties.

Summary: This study investigated the endogenous hormone response mechanism of Styrax tonkinensis to waterlogging stress. The results showed changes in several phytohormones and identified differentially expressed genes (DEGs) involved in hormone synthesis and signaling pathways. The research provides insights into the molecular response of S. tonkinensis to waterlogging and could contribute to improving its ability to withstand waterlogging stress.

Summary: In this study, we found that both low Fe and NaCl significantly inhibited the growth of seminal roots in wheat seedlings. Sufficient Fe caused greater growth cessation of the seminal roots than low Fe under salt stress. Low Fe alleviated the salinity-induced growth cessation of seminal roots by responding to local low Fe signals in the roots.

Summary: This study investigated the root characteristics of wheat under different growth environments, with a focus on seminal and nodal roots. Through genome-wide association analysis, 35 quantitative trait loci associated with root traits were identified, including 14 stable SNPs related to the number of nodal roots per plant. This information provides valuable insights into the study of wheat root traits.

Summary: The study investigated the genetic regulation of waterlogging stress in wheat using PacBio SMRT and Illumina sequencing, revealing a large number of non-coding RNAs, fusion genes, and transcription factors. The results showed downregulation of photosynthesis-related genes and upregulation of steroid biosynthesis, steroid hormone biosynthesis, and plant hormone signal transduction genes after waterlogging treatment, with YM158 displaying different genetic regulation patterns compared to XM55.

Summary: In this study, 17 PtPR1 genes were identified in the genome of Populus trichocarpa, and they showed different responses to drought stress, fungal pathogen Septotinia populiperda, and insect attacks. The subfamily B of PtPR1 genes played an important role in response to biotic stress. A new resistance gene PtPR1A was identified.

Summary: PR-1 proteins in Qingke plants are important in stress response and development, but their functions are not well understood. This study identified 20 PR-1 genes in Qingke with conserved features and diverse promoter motifs. Phylogenetic analysis showed that most Qingke PR-1 proteins belong to clade I. Gene structure analysis revealed intron variations. Expression analysis indicated that several PR-1 genes are induced by powdery mildew infection, phytohormones, and cold stimulus. These findings contribute to our understanding of PR-1 family members in Qingke plants and provide a basis for further exploration of their functions.

Summary: This study identified differentially expressed genes (DEGs) through transcriptome analysis in two onion genotypes (Acc. 1666 and W-344) with contrasting responses to waterlogging stress. The proteins coded by these DEGs regulate key biological processes such as phytohormone production, antioxidant enzymes, programmed cell death, and energy production. The results provide valuable molecular information for improving stress tolerance and developing waterlogging tolerant onion varieties.

Summary: In this study, 22 ADH genes were identified from the wheat genome, which could be divided into two subfamilies, with majority of them belonging to the Medium-chain ADH subfamily. Sequence alignment analysis showed that these genes were relatively conservative and contained similar anaerobic response elements. Experimental results revealed that key ADH genes played significant roles in waterlogging tolerance in wheat seeds.

Summary: This study analyzed the characteristics and functions of PR-4 gene family in Qingke. Four PR-4 genes were identified in the genome of Qingke, and phylogenetic analysis revealed their classification into group I. Various active elements involved in response to biotic and abiotic stresses were found in the promoters of Qingke PR-4 genes. Expression profiling confirmed their involvement in defense response against drought, cold, and powdery mildews infection, and their regulation by different hormones.

Summary: This study revealed the growth and hormone changes in wheat seedlings under drought conditions. Reduced leaf growth and maintained root growth were observed under drought treatment. The concentration of gibberellins (GAs) was slightly increased in the root tips compared to the leaves. In addition, the concentrations of other stress-related hormones, such as abscisic acid and salicylic acid, also varied.

Summary: Rhizosphere colonization is essential for the beneficial application of plant growth-promoting rhizobacteria. This study investigated the colonization traits of the phosphate-solubilizing strain Pseudomonas sp. WS32 on wheat roots. The results showed that the WS32 strain could survive in the wheat rhizosphere for extended periods and expand into new zones. The colonization of WS32 resulted in significant increases in seedling and root growth, as well as phosphorus accumulation in wheat leaves. RNA sequencing revealed differential gene expression in wheat roots under WS32 colonization, involving various functional categories related to nutrient transport, hormone metabolism, signal recognition, membrane transport, and transcription factor regulation.
