“…Using Actin as internal reference gene, several important downstream stress related genes of MYB were detected by qPCR. These genes were AtDREB1A ( Lu et al., 2017 ), AtCOR15a ( Steponkus et al., 1998 ), AtERD10B ( Du and Li, 2019 ), AtCOR47 ( Song et al., 2021 ), AtSnRK2.4 ( Nakashima and Yamaguchi-Shinozaki, 2013 ), AtRD29A ( Wu et al., 2022 ), AtSOD1 ( Li J. et al., 2022 ) and AtP5CS1 ( Chen et al., 2015 ). The reaction procedure and system of qPCR were the same as above methods.…”

Cold and drought stress considerably suppress the development of plants. In this study, a new MYB (v-myb avian myeloblastosis viral)TF gene, MbMYBC1, was isolated from the M. baccata and located in nucleus. MbMYBC1 has a positive response to low temperature and drought stress. After being introduced into Arabidopsis thaliana, the physiological indicators of transgenic Arabidopsis had corresponding changes under these two stresses, the activities of catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD) increased, electrolyte leakage rate (EL) and the content of proline increased, but the content of chlorophyll decreased. In addition, its overexpression can also activate the downstream expression of AtDREB1A, AtCOR15a, AtERD10B and AtCOR47 related to cold stress and AtSnRK2.4, AtRD29A, AtSOD1and AtP5CS1 related to drought stress. Based on these results, we speculate that MbMYBC1 can respond to cold and hydropenia signals, and can be used in transgenic technology to improve plant tolerance to low temperature and drought stress.

“…For example, the overexpression of FvSAMDC enhanced salt tolerance in tobacco [154]. In Arabidopsis, the overexpression of CsSAMDC2 exhibited higher levels of salt and drought tolerance than its wild type [155]. Meanwhile, the ectopic expression of GhSAMDC3 can improve salt tolerance in Arabidopsis by increasing Spd content and activating salt-tolerance-related genes [156].…”

“…For example, the interaction between CsCDPK6 and CsSAMS1 negatively regulates the biosynthesis of plant ET, inhibiting SAMDC, resulting in a decrease in Put conversion to Spd and Spm [86]. Wu et al [155] overexpressed the PAs related gene CsSAMDC2 in Arabidopsis to improve salt tolerance, and the expression levels of the ET and ABA responding genes also increased. In a recent report, Freitas et al [175] found that ET regulated the H 2 O 2 content derived from PA decomposition enzymes, inducing salt tolerance in maize.…”

Salinity is a major abiotic stress that restricts cotton growth and affects fiber yield and quality. Although studies on salt tolerance have achieved great progress in cotton since the completion of cotton genome sequencing, knowledge about how cotton copes with salt stress is still scant. S-adenosylmethionine (SAM) plays important roles in many organelles with the help of the SAM transporter, and it is also a synthetic precursor for substances such as ethylene (ET), polyamines (PAs), betaine, and lignin, which often accumulate in plants in response to stresses. This review focused on the biosynthesis and signal transduction pathways of ET and PAs. The current progress of ET and PAs in regulating plant growth and development under salt stress has been summarized. Moreover, we verified the function of a cotton SAM transporter and suggested that it can regulate salt stress response in cotton. At last, an improved regulatory pathway of ET and PAs under salt stress in cotton is proposed for the breeding of salt-tolerant varieties.

Proteases help plants maintain protein quality and break down protein subsets in reply to environmental, developmental, biotic, and abiotic stressors. Filamentation temperature-sensitive H (FtsH) is an ATP-dependent metalloprotease detected in both prokaryotes and eukaryotes cells. The present research, the FtsH gene in the bean, which has an important place in the legume family and is an important agricultural product, was characterized for the first time using various bioinformatic tools, and qRT-PCR measured its expression level. In the study, effectively identified and characterized 17 FtsH genes present in genome the of Phaseolus vulgaris. The MW of FtsH proteins varied from 71.16 to 147.07 kDa, their amino acid lengths ranged from 642 to 1284, and their pI values varied from 5.39 to 9.60. Interestingly, the distribution of these 17 distinct PvFtsH genes across the 8 chromosomes was not uniform, exhibiting an uneven pattern throughout the genome. A pair of segmental duplication fragments were found, revealing probable processes of gene expansion and evolution. Collinearity with related genes in Arabidopsis and rice was thoroughly examined to determine the evolutionary conservation and differentiation of PvFtsH genes. Additionally, we used RNAseq and qRT-PCR to investigate the expression patterns of PvFtsH in leaf tissue under salt and drought conditions. Our data showed unique expression patterns, suggesting PvFtsH may respond to environmental and physiological stressors. Overall, this work makes major contributions to our understanding of PvFtsH genes and their roles in the context of gene evolution, chromosomal distribution, and expression patterns under various environmental situations.
