“…2E) and hormone treatments with ABA or JA (Fig. 2A and B), consistent with previous reports (Frandsen et al 2001;Jing et al 2020), suggesting that OsClo5 is capable of responding to most stresses as a positive regulator and may function in the stress-related oxylipin signalling pathway. Another caleosin that is regulated by multiple stresses and hormones is AtCLO3 in Arabidopsis (Shen et al 2014); however, in contrast to the AtCLO3 results, our experiments clearly demonstrated that cold treatment induced rapid inhibition of OsClo5 expression after 3 h (Fig.…”

Caleosin is a lipid droplet-binding protein involved in maintenance of the lipid droplet structure and in signal transduction. However, the role of caleosin proteins in stress resistance is limited. Here, we report data for a rice caleosin protein gene, OsClo5, involved in cold stress tolerance via influence and regulation of the JA signalling pathway.• Overexpression lines and RNAi lines of OsClo5 were subjected to cold stress and recovery to measure electrolyte leakage and survival rate. Changes were also detected in the genome-wide transcriptome of OsClo5 overexpressed plants.• OsClo5 is located mainly in lipid droplets and expressed in all tissues tested. Its expression was upregulated by various stress conditions when subjected to cold treatment. Overexpression of OsClo5 decreased cold tolerance, and RNAi lines of OsClo5 had higher survival than WT seedlings. OsClo5 inhibited one jasmonate biosynthetic gene and several jasmonate ZIM domain (JAZ) genes, which were upregulated in response to cold stress.• OsClo5 is a constitutively expressed caleosin protein that regulates plant cold resistance through inhibition of jasmonate signalling and JA synthesis.

“…This confers the reduced sensitivity to salinity or the enhanced tolerance to salt stress in rice seedlings in comparison with wild-type. Thus, OsClo5 negatively affected salt stress tolerance in rice in cooperation with the transaction repression control of OsDi19-5 to two target genes OsUSP and OsMST in rice ( Jing et al, 2021 ).…”

Globally, sodicity is one of the major abiotic stresses limiting the wheat productivity in arid and semi-arid regions. With due consideration, an investigation of the complex gene network associated with sodicity stress tolerance is required to identify transcriptional changes in plants during abiotic stress conditions. For this purpose, we sequenced the flag leaf transcriptome of a highly tolerant bread wheat germplasm (KRL 3–4) in order to extend our knowledge and better understanding of the molecular basis of sodicity tolerance. A total of 1,980 genes were differentially expressed in the flag leaf due to sodicity stress. Among these genes, 872 DEGs were upregulated and 1,108 were downregulated. Furthermore, annotation of DEGs revealed that a total of 1,384 genes were assigned to 2,267 GO terms corresponding to 502 (biological process), 638 (cellular component), and 1,127 (molecular function). GO annotation also revealed the involvement of genes related to several transcription factors; the important ones are expansins, peroxidase, glutathione-S-transferase, and metal ion transporters in response to sodicity. Additionally, from 127 KEGG pathways, only 40 were confidently enriched at a p-value <0.05 covering the five main KEGG categories of metabolism, i.e., environmental information processing, genetic information processing, organismal systems, and cellular processes. Most enriched pathways were prioritized using MapMan software and revealed that lipid metabolism, nutrient uptake, and protein homeostasis were paramount. We have also found 39 SNPs that mapped to the important sodicity stress-responsive genes associated with various pathways such as ROS scavenging, serine/threonine protein kinase, calcium signaling, and metal ion transporters. In a nutshell, only 19 important candidate genes contributing to sodicity tolerance in bread wheat were identified, and these genes might be helpful for better understanding and further improvement of sodicity tolerance in bread wheat.
