“…In F. benghalensis species, 15 out of 17 MSA genes were also associated with tolerance against environmental stress responses in plants. The genes were mainly involved in tolerance against drought, oxidative stress, osmotic stress, and other abiotic and biotic stress responses against pathogens ( Afzal et al., 2016 ; Almaghrabi et al., 2019 ; Ghosh et al., 2022 ; Singh et al., 2018 ; Wi et al., 2020 ) ( Table S23 ). In F. religiosa , 17 out of 19 MSA genes were known associated with stress tolerance activities of plants such as osmotic stress, oxidative stress, other ABA-mediated abiotic stress, and phytohormones signaling-based pathogen defense responses ( Kachroo et al., 2003 ; Li et al., 2019b ; Sharma et al., 2018 ; Yuan et al., 2018 ) ( Table S24 ).…”

“…The peroxisome pathway was involved in eliminating exceeded ROS generated by various stresses and balancing the ROS level. The proteins of PEX7 and MPV17 exist on the peroxisome membrane, of which AtMPV17 contributes to osmotic stress tolerance in plants ( Wi et al, 2020 ), while PEX7 acts as an import receptor of peroxisomal-targeting signal PTS2 ( Woodward and Bartel, 2005 ). In the present study, 15 DEGs existed significant changes and were enriched in the peroxisome pathway (ko04146) in leaves and/or roots in Eutrema , among which the transcript level of five genes were obviously upregulated in salt-treated leaves, including EsPEX7 (Thhalv10008237m) and EsMPV17 (Thhalv10025993m) ( Figures 6D,E , Supplementary Table S10 ).…”

“…Vac8 genes are related to autophagy initiation; they coordinate the site of autophagosome formation with vacuole fusion and improve the efficiency of autophagy by localizing autophagosome formation within the cell ( Hollenstein et al, 2019 ). In the peroxisome pathway, the function of Mpv17, CAT, and SOD is related to ROS metabolism and could contribute to the stress tolerance of plants ( Wang et al, 2004 ; Wi et al, 2020 ). Peroxisomes, as a metabolic organelle, typically contain enzymes involved in the lipid metabolism, and the catalase convert H 2 O 2 to water and O 2 ( Van den Bosch et al, 1992 ; Wanders et al, 2001 ).…”

Eutrema salsugineum can grow in natural harsh environments; however, the underlying mechanisms for salt tolerance of Eutrema need to be further understood. Herein, the transcriptome profiling of Eutrema leaves and roots exposed to 300 mM NaCl is investigated, and the result emphasized the role of genes involved in lignin biosynthesis, autophagy, peroxisome, and sugar metabolism upon salt stress. Furthermore, the expression of the lignin biosynthesis and autophagy-related genes, as well as 16 random selected genes, was validated by qRT-PCR. Notably, the transcript abundance of a large number of lignin biosynthesis genes such as CCoAOMT, C4H, CCR, CAD, POD, and C3′H in leaves was markedly elevated by salt shock. And the examined lignin content in leaves and roots demonstrated salt stress led to lignin accumulation, which indicated the enhanced lignin level could be an important mechanism for Eutrema responding to salt stress. Additionally, the differentially expressed genes (DEGs) assigned in the autophagy pathway including Vac8, Atg8, and Atg4, as well as DEGs enriched in the peroxisome pathway such as EsPEX7, EsCAT, and EsSOD2, were markedly induced in leaves and/or roots. In sugar metabolism pathways, the transcript levels of most DEGs associated with the synthesis of sucrose, trehalose, raffinose, and xylose were significantly enhanced. Furthermore, the expression of various stress-related transcription factor genes including WRKY, AP2/ERF-ERF, NAC, bZIP, MYB, C2H2, and HSF was strikingly improved. Collectively, the increased expression of biosynthesis genes of lignin and soluble sugars, as well as the genes in the autophagy and peroxisome pathways, suggested that Eutrema encountering salt shock possibly possess a higher capacity to adjust osmotically and facilitate water transport and scavenge reactive oxidative species and oxidative proteins to cope with the salt environment. Thus, this study provides a new insight for exploring the salt tolerance mechanism of halophytic Eutrema and discovering new gene targets for the genetic improvement of crops.

“…Marker A3190, which we determined to have a significant relationship DSI on leaves at the 50–60% boll opening period, was located on the protein Mpv17-like (LOC107948714) gene, and it has been reported that Mpv17 contributes to osmotic stress tolerance in plants [ 23 ]. Considering the fact that Verticillium wilt restricts the water and substance transport of the plant by occluding the plant transmission bundles and thus increasing the osmotic pressure, our observation seems reasonable.…”

Cotton (Gossypium spp.) is the best plant fiber source in the world and provides the raw material for industry. Verticillium wilt caused by Verticillium dahliae Kleb. is accepted as a major disease of cotton production. The most practical way to deal with verticillium wilt is to develop resistant/tolerant varieties after cultural practices. One of the effective selections in plant breeding is the use of marker-assisted selection (MAS) via quantitative trait loci (QTL). Therefore, in this study, we aimed to discover the genetic markers associated with the disease. Through the association mapping analysis, common single nucleotide polymorphism (SNP) markers were obtained using 4730 SNP alleles. As a result, twenty-three markers were associated with defoliating (PYDV6 isolate) pathotype, twenty-one markers with non-defoliating (Vd11 isolate) pathotype, ten QTL with Disease Severity Index (DSI) of the leaves at the 50–60% boll opening period and eight markers were associated with DSI in the stem section. Some of the markers that show significant associations are located on protein coding genes such as protein Mpv17-like, 21 kDa protein-like, transcription factor MYB113-like, protein dehydration-induced 19 homolog 3-like, F-box protein CPR30-like, extracellular ribonuclease LE-like, putative E3 ubiquitin-protein ligase LIN, pentatricopeptide repeat-containing protein At3g62890-like, fructose-1,6-bisphosphatase, tubby-like F-box protein 8, endoglucanase 16-like, glucose-6-phosphate/phosphate translocator 2, metal tolerance protein 11-like, VAN3-binding protein-like, transformation/transcription domain-associated protein-like, pyruvate kinase isozyme A, ethylene-responsive transcription factor CRF2-like, molybdate transporter 2-like, IRK-interacting protein-like, glycosylphosphatidylinositol anchor attachment 1 protein, U3 small nucleolar RNA-associated protein 4-like, microtubule-associated protein futsch-like, transport and Golgi organization 2 homolog, splicing factor 3B subunit 3-like, mediator of RNA polymerase II transcription subunit 15a-like, putative ankyrin repeat protein, and protein networked 1D-like. It has been reported in previous studies that most of these genes are associated with biotic and abiotic stress factors. As a result, once validated, it would be possible to use the markers obtained in the study in Marker Assisted Selection (MAS) breeding.
