“…Proteins DREB2 require posttranscriptional modifications for operation, and they directly interact with DRE1 and DRE2 motifs present in the promoter region of HsfA3 and operate its expression. In the next step, Hsf3A controls expressions of HSPs as reported by Li et al (2017). A DREB2A homolog DREB2C also induces expression of the HsfA3 gene even under normal conditions, which indicates a potential role of DREB2C for induction of HsfA3 under stress conditions (Chen et al 2010).…”

“…Plants have many TF families having dozens of members and showing unique properties compared with animals. The plant HSFs are broadly classified into three classes: A, B, and C. This classification depends upon the presence of a DNAbinding domain and an oligomerization domain (Li et al 2017). All HSFs share heat shock elements in their promoter regions, which indicates that they are either auto-regulated or other HSFs operate their expressions.…”

“…3). Enhanced expression of HsfA3 in hsfa2 mutant plants shows that it directly interacts with HsfA2 but they can also work independently (Li et al 2017). This interaction has also been justified by treatment with β-galactosidase, nutritional deficiencies, and in a yeast two hybrid test system (Aumond et al 2017.…”

“…Genetic and expression analyses have indicated that HsfA3 is present downstream to the HsfA2. They function in the same regulatory pathways, but the role of former is less significant (Li et al 2017). They have a direct interaction at the protein level (Fig.…”

“…Climate change and global warming lead to frequent heat waves that damage plants not only by a change in diurnal temperature but also by occurrence of episodes of heatstress, which impairs normal homeostasis. A high temperature interferes with all chemical processes and results in cell damage ultimately decreasing plant growth and yield (Li et al 2017). To survive under a high temperature, plants have to sense ambient temperature accurately and respond to its changes.…”

The climate shift has resulted in frequent heat waves, which cause damaging effects on plant growth and development at different life stages. All cellular processes in plants are highly sensitive to a high temperature. The plasma membrane heat receptors usually sense temperature variations directly or via a change in membrane fluidity. The accumulation of damaged proteins and reactive oxygen species also aid in heat perception. Calcium ions and heat sensors transfer signals to transcription factors through a series of signaling cascades. The heat stress transcription factors (HSFs) effectively regulate expression of heat induced genes. The members of the heat shock transcription factor A1 (HsfA1s) family are master regulators of a heat stress response. Different HSFs interact with each other at different levels and simultaneously operate heat induced gene expression. Interaction of HSFs with each other on multiple levels provides chances for manipulation to improve plant heat stress tolerance.

Zoysiagrasses (Zoysia spp.) are relatively low‐input and warm‐season turfgrasses which have grown in popularity in the United States since their introduction in the 1890s. Over 30 improved zoysiagrass cultivars were released in the past three decades, but many lack freezing tolerance and their use is limited to warm‐humid climates. Understanding the genetic controls of winter hardiness and freezing tolerance in zoysiagrass could considerably benefit the breeding efforts to increase tolerance to freezing stress. In the present study, controlled environment acclimation and freezing tests were used to evaluate a Meyer × Victoria zoysiagrass mapping population for post‐freezing surviving green tissue (SGT) and regrowth (RG). Quantitative trait loci (QTL) mapping analysis identified nine QTL associated with SGT, eight QTL linked to RG, and 22 QTL common in both traits, accounting for between 6.4 and 12.2% of the phenotypic variation. Eleven regions of interest overlapped with putative winter injury QTL identified in a previous field study. Upon sequence analysis, homologs of several abiotic response genes were found underlying these overlapping QTL regions. The homologs of these gene encode transcription factors, cell wall modification‐related proteins, and defense signal transduction‐related proteins. After further validation, these QTL and their associated markers have potential to be used in future breeding efforts for the development of a broader pool of zoysiagrass cultivars capable of surviving in cold climates.

Heat stress has detrimental impacts on wheat growth and yield formation. Conferring heat tolerance through applying plant growth regulators is a feasible strategy to reduce loss. Gamma aminobutyric acid (GABA) is a four-carbon non-proteinogenic amino acid existing in organisms and accumulates in response to stress. In this study, spring wheat Liaochun17 and winter wheat Jingdu 40 were used to investigate the function of exogenous GABA on the heat tolerance of wheat seedlings. Data displayed that GABA treatment not only reduced the production of reactive active oxygen (ROS), but also improved the scavenging capacity of diphenyl picryl phenyl hydrazine active oxygen under heat stress, thus alleviating the accumulation of malondialdehyde and the damage of cell membrane. In addition, analysis of protein and amino acids revealed that GABA effectively promoted the accumulation of soluble protein and coordinated amino acid homeostasis. Summarily, our current findings revealed that GABA strengthened the resistance of wheat seedling to heat stress by maintaining the metabolism balance of ROS and amino acids.
