TaWRKY24 integrates the tryptophan metabolism pathways to participate in defense against Fusarium crown rot in wheat.

Wheat growth process has been experiencing severe challenges arising from the adverse environment. Notably, the incidence of Fusarium crown rot (FCR), a severe soil-borne disease caused by Fusarium pseudograminearum (Fp), has significantly intensified in various wheat-growing regions, resulting in a decline in grain yield. However, the identification of wheat varieties and the exploration of effective gene resources resistant to FCR have not yet been accomplished.

TaMYB-CC5 gene specifically expressed in root improve tolerance of phosphorus deficiency and drought stress in wheat.

Phosphate deficiency and drought are significant environmental constraints that impact both the productivity and quality of wheat. The interaction between phosphorus and water facilitates their mutual absorption processes in plants. Under conditions of both phosphorus deficiency and drought stress, we observed a significant upregulation in the expression of wheat MYB-CC transcription factors through the transcriptome analysis.

Heat shock protein TaHSP17.4, a TaHOP interactor in wheat, improves plant stress tolerance.

Adaptation to drought and salt stresses is a fundamental part of plant cell physiology and is of great significance for crop production under environmental stress. Heat shock proteins (HSPs) are molecular chaperones that play a crucial role in folding, assembling, translocating, and degrading proteins. However, their underlying mechanisms and functions in stress tolerance remain elusive.

A WRKY transcription factor, TaWRKY42-B, facilitates initiation of leaf senescence by promoting jasmonic acid biosynthesis.

Background: Leaf senescence comprises numerous cooperative events, integrates environmental signals with age-dependent developmental cues, and coordinates the multifaceted deterioration and source-to-sink allocation of nutrients. In crops, leaf senescence has long been regarded as an essential developmental stage for productivity and quality, whereas functional characterization of candidate genes involved in the regulation of leaf senescence has, thus far, been limited in wheat.

Results: In this study, we analyzed the expression profiles of 97 WRKY transcription factors (TFs) throughout the progression of leaf senescence in wheat and subsequently isolated a potential regulator of leaf senescence, TaWRKY42-B, for further functional investigation.

Genome-wide identification and expression analysis of the calmodulin-binding transcription activator (CAMTA) gene family in wheat (Triticum aestivum L.).

Background: Plant calmodulin-binding transcription activator (CAMTA) proteins play important roles in hormone signal transduction, developmental regulation, and environmental stress tolerance. However, in wheat, the CAMTA gene family has not been systematically characterized.

Results: In this work, 15 wheat CAMTA genes were identified using a genome-wide search method.

Transcriptome analysis of activated charcoal-induced growth promotion of wheat seedlings in tissue culture.

Background: Activated charcoal (AC) is highly adsorbent and is often used to promote seedling growth in plant tissue culture; however, the underlying molecular mechanism remains unclear. In this study, root and leaf tissues of 10-day-old seedlings grown via immature embryo culture in the presence or absence of AC in the culture medium were subjected to global transcriptome analysis by RNA sequencing to provide insights into the effects of AC on seedling growth.

Results: In total, we identified 18,555 differentially expressed genes (DEGs).

Characterizing the Role of in Salt Tolerance.

The WRKY transcription factor superfamily is known to participate in plant growth and stress response. However, the role of this family in wheat ( L.) is largely unknown.

MR imaging of cartilage repair surgery of the knee.

Articular cartilage is a complex tissue with unique properties that are essential for normal joint function. Many processes can result in cartilage injury, ranging from acute trauma to degenerative processes. Articular cartilage lacks vascularity, and therefore most chondral defects do not heal spontaneously and may require surgical repair.

BES/BZR Transcription Factor TaBZR2 Positively Regulates Drought Responses by Activation of .

BRI1-EMS suppressor (BES)/brassinazole-resistant (BZR) family transcription factors are involved in a variety of physiological processes, but the biological functions of some BES/BZR transcription factors remain unknown; moreover, it is not clear if any of these proteins function in the regulation of plant stress responses. Here, wheat () brassinazole-resistant 2 ()-overexpressing plants exhibited drought tolerant phenotypes, whereas downregulation of in wheat by RNA interference resulted in elevated drought sensitivity. electrophoretic mobility shift assay and luciferase reporter analysis illustrate that TaBZR2 directly interacts with the gene promoter to activate the expression of glutathione s-transferase-1 (), which functions positively in scavenging drought-induced superoxide anions (O ).

Identification and characterization of GmMYB118 responses to drought and salt stress.

Background: Abiotic stress severely influences plant growth and development. MYB transcription factors (TFs), which compose one of the largest TF families, play an important role in abiotic stress responses.

Result: We identified 139 soybean MYB-related genes; these genes were divided into six groups based on their conserved domain and were distributed among 20 chromosomes (Chrs).

Maize WRKY Transcription Factor ZmWRKY106 Confers Drought and Heat Tolerance in Transgenic Plants.

WRKY transcription factors constitute one of the largest transcription factor families in plants, and play crucial roles in plant growth and development, defense regulation and stress responses. However, knowledge about this family in maize is limited. In the present study, we identified a drought-induced WRKY gene, , based on the maize drought transcriptome sequencing data.

The Maize WRKY Transcription Factor ZmWRKY40 Confers Drought Resistance in Transgenic .

Abiotic stresses restrict the growth and yield of crops. Plants have developed a number of regulatory mechanisms to respond to these stresses. WRKY transcription factors (TFs) are plant-specific transcription factors that play essential roles in multiple plant processes, including abiotic stress response.
