“…To test this hypothesis, we analyzed the transcriptional dynamics of several HSR genes belonging to Cluster 2 at 24 h, 48 h, 4 days, and 7 days after being exposed to the control temperature, 21 °C, and 29 °C in both varieties. Thus, we monitored the pattern of expression of four well-known core HSR genes, including the small heat-shock protein, BnHSP17.6 ; the ATP-dependent chaperone of the HSP70 family, BnHSP70 ; the mitochondrion-localized small heat-shock protein, BnHSP23.6M ; and the HS-induced galactinol synthase, BnGolS1 , by qPCR ( Figure 7 C) [ 42 , 43 ]. As expected, we found that all these genes started to increase their expression at 24 h after 29 °C exposure.…”

Elevated growth temperatures are negatively affecting crop productivity by increasing yield losses. The modulation of root traits associated with improved response to rising temperatures is a promising approach to generate new varieties better suited to face the environmental constraints caused by climate change. In this study, we identified several Brassica napus root traits altered in response to warm ambient temperatures. Different combinations of changes in specific root traits result in an extended and deeper root system. This overall root growth expansion facilitates root response by maximizing root–soil surface interaction and increasing roots’ ability to explore extended soil areas. We associated these traits with coordinated cellular events, including changes in cell division and elongation rates that drive root growth increases triggered by warm temperatures. Comparative transcriptomic analysis revealed the main genetic determinants of these root system architecture (RSA) changes and uncovered the necessity of a tight regulation of the heat-shock stress response to adjusting root growth to warm temperatures. Our work provides a phenotypic, cellular, and genetic framework of root response to warming temperatures that will help to harness root response mechanisms for crop yield improvement under the future climatic scenario.

Rice serves as a principal food class globally and the crop have been gradually impeded by environmental constraints such as drought, floods, salinity, heat, and cold. Plants adapt their physiological operations in response to external stimuli via signal transduction, thereby modulates gene expression and triggers a range of cellular responses. To feed the current population expansion, it is necessary to develop crops which are able to withstand climate change is highly desirable. OsDHSRP1 is an E3-ubiquitin ligase whose expression is highly stimulated by salinity, heat, and drought conditions, and it acts as a negative modulator by boosting ROS production. The genome-wide comprehensive and expression analysis of OsDHSRP1 in rice have still not been reported. In the current research, we are providing genome wide prediction, structural, evolutionary characterization, and expression analysis of OsDHSRP gene family of Oryza under diverse abiotic stresses. A total of 15 OsDHSRP genes were discovered in Oryza genome, which contains C3HC4 zinc finger conserved domain. The elucidation of Intron/Exon and motif patterns provide structural aspects of these genes. Cis-regulatory analysis and Transcription factor prediction studies revealed their roles and interaction with genes involved in multiple abiotic variables. Expression evaluation of OsDHSRP genes by q-RT PCR revealed that OsDHSRP1 exhibited strong expression trends in leaflets during cold stress followed by drought and salt stress conditions, suggests the role of OsDHSRP1 under diverse abiotic stress circumstances in Oryza. This study provides further insights into regulation of expression of OsDHSRP genes for developing climate resilient crops.

“…High temperature is one of the major abiotic stresses that limits plant growth and production. In response to high temperature signals, plants can activate diverse pathways encompassing phytohormone signal transduction (e.g., ABA, SA, JA), transcriptional regulation (e.g., HSF, NAC, MYB, bZIP, WRKY), and epigenetic regulation (Huang et al, 2022). Among these mechanisms, the HSF ‐ HSP pathway has been extensively investigated (Ohama et al, 2017; Zhou et al, 2022).…”

Sirtuins (SRTs) are a group of nicotinamide adenine dinucleotide (NAD+)‐dependent deacetylase that target both histone and nonhistone proteins. The biological function of SRT in horticultural plants has been rarely studied. In this study, FaSRT1‐2 was identified as a key member of the 8 FaSRTs encoded in cultivated strawberry genome. Transient overexpression of FaSRT1‐2 in strawberry fruit accelerated ripening, increased the content of anthocyanins and sugars, enhanced ripening‐related gene expression. Moreover, stable transformation of FaSRT1‐2 in strawberry plants resulted in enhanced vegetative growth, increased sensitivity to heat stress and increased susceptibility to Botrytis cinerea infection. Interestingly, knocking out the homologous gene in woodland strawberry had the opposite effects. Additionally, we found the content of stress‐related hormone abscisic acid (ABA) was decreased, while the growth‐related gibberellin (GA) concentration was increased in FaSRT1‐2 overexpression lines. Gene expression analysis revealed induction of heat shock proteins, transcription factors, stress‐related and antioxidant genes in the FaSRT1‐2‐overexpressed plants while knocked‐out of the gene had the opposite impact. In conclusion, our findings demonstrated that FaSRT1‐2 could positively promote strawberry plant vegetative growth and fruit ripening by affecting ABA and GA pathways. However, it negatively regulates the resistance to heat stress and B. cinerea infection by influencing the related gene expression.
