Summary: Plants face a more volatile environment due to their immobility, prompting the development of efficient mechanisms to adapt to stress. MYB transcription factors, a widespread family in plants, play critical roles in plant development and responses to stresses. Multiple studies have shown that MYB proteins are involved in diverse roles in responses to abiotic stresses, but their regulatory mechanism is still not well understood.

Summary: Changes in gene expression are crucial for responses to abiotic stress. Transcriptome profiling of heat- or cold-stressed maize genotypes reveals many alterations in transcript abundance. By analyzing expression responses in multiple genotypes and identifying cis- or trans-regulatory variation, predictive models of gene expression responses for thermal stress-responsive genes can be developed. Models focusing on unmethylated regions near the transcription start sites (TSSs) show improved accuracy, suggesting that different genes may have varying response dynamics to stress.

Summary: Salinity and drought stresses have significant effects on plant growth and crop production. Auxin, a chemical messenger, plays a crucial role in regulating plants' adaptative response to these stresses through the DNA-binding AUXIN RESPONSE FACTORS (ARFs). Different ARFs are involved in regulating soluble sugar content, promoting root development, and maintaining chlorophyll content to help plants adapt to drought and saline stress conditions. Yet, the functional characterization of ARFs in response to these stresses is still limited. Additionally, the post-transcriptional regulation of ARF expression by small RNAs has been shown to influence plant responses to these stresses. This review summarizes recent research on ARFs, including gene expression patterns, functional characterization, and post-transcriptional regulation, in the context of drought and salinity stresses.

Summary: Extensive research has been done to study plant transcription factors involved in abiotic stress responses, and efforts have been made to improve stress tolerance by manipulating these genes. The bHLH transcription factor family, which contains a highly conserved bHLH motif, is important in regulating plant physiology and response to abiotic stresses such as drought and excessive salinity. The regulation of bHLH transcription factors occurs at both the transcriptional and post-translational levels through various modifications. This review article focuses on the structural characteristics, classification, function, and regulatory mechanism of bHLH transcription factors in response to abiotic stresses.

Summary: Understanding the metabolism and regulation of reactive oxygen species (ROS) is crucial for improving plant growth and developing stress-tolerant cultivars. This review summarizes current research on ROS generation and scavenging in plants, as well as recent progress in transcription factor-mediated regulation of ROS metabolism. It also discusses the effects of applying exogenous substances on ROS metabolism under abiotic stress.

Summary: The study in the Huang-Huai-Hai Plain of China found that using new deep vertical rotary tillage (DVRT) can significantly reduce soil bulk density, increase winter wheat yield, and improve water and nitrogen use efficiency. Under different productivity levels, the effects of DVRT on grain yield, nitrogen partial factor productivity (PFPN), and water use efficiency (WUE) were significantly better than conventional shallow rotary tillage (CT).

Summary: A cadmium-loving fungal strain YZ1 was isolated from wheat farmland soil, and rhizoremediation with YZ1 significantly reduced cadmium concentration in wheat seedlings. Comparative transcriptomics showed that at 2mM cadmium, YZ1 could modulate wheat's cadmium response by affecting cadmium-associated genes in wheat.

Summary: In this study, a WRKY gene designated as SbWRKY45 was isolated and characterized from sorghum. The results showed that SbWRKY45 was significantly up-regulated in response to drought and salt stress, and exhibited a stress response in different sorghum tissues. Overexpression of SbWRKY45 increased germination rates and promoted root growth in transgenic Arabidopsis under drought stress. Therefore, SbWRKY45 may play a vital role in the abiotic stress response of sorghum.
