“…To understand and improve stress responses and tolerances in crop species, researchers have focused on the signaling perception mechanisms, transcriptional regulation and expression of functional proteins in the stress response 58 . Previous studies found that NAC transcription factors are involved in plant development and biotic and abiotic stress regulation 59 ; WRKY transcription factors are important components of many aspects in the plant defense systems and in plant abiotic stress responses 60 ; HSPs, which were originally identified as heat-inducible gene products, are a family of highly conserved proteins that respond to a wide variety of stresses including oxidative and thermal stress 61 ; CYP450 proteins function as growth and developmental signals and protect plants from various biotic and abiotic stresses 62 ; WD40s play a key role in protein-protein and protein-DNA interactions by acting as scaffolding molecules, promoting protein activity and responsiveness to salt stress 63 ; ZnF and LRR family proteins play regulatory roles in immune responses 64, 65 ; aquaporins regulate the movement of water and other small molecules across plant vacuolar and plasma membranes, and are associated with plant tolerance of biotic and abiotic stresses 66 ; MAPK cascade is one of the universal signaling pathways involved in responses to external stimuli, which play a crucial role in plant growth and development as well as biotic and abiotic stress responses 67 . In this study, we selected 535 ILP markers derived from these nine gene families that are related to stress responses for structural and functional identification.…”

Intron length polymorphisms (ILPs), a type of gene-based functional marker, could themselves be related to the particular traits. Here, we developed a genome-wide cotton ILPs based on orthologs annotation from two sequenced diploid species, A-genome Gossypium arboreum and D-genome G. raimondii. We identified 10,180 putative ILP markers from 5,021 orthologous genes. Among these, 535 ILP markers from 9 gene families related to stress were selected for experimental verification. Polymorphic rates were 72.71% between G. arboreum and G. raimondii and 36.45% between G. hirsutum acc. TM-1 and G. barbadense cv. Hai7124. Furthermore, 14 polymorphic ILP markers were detected in 264 G. hirsutum accessions. Coupled with previous simple sequence repeats (SSRs) evaluations and salt tolerance assays from the same individuals, we found a total of 25 marker-trait associations involved in nine ILPs. The nine genes, temporally named as C1 to C9, showed the various expressions in different organs and tissues, and five genes (C3, C4, C5, C7 and C9) were significantly upregulated after salt treatment. We verified that the five genes play important roles in salt tolerance. Particularly, silencing of C4 (encodes WRKY DNA-binding protein) and C9 (encodes Mitogen-activated protein kinase) can significantly enhance cotton susceptibility to salt stress.

“…Most commonly, SAP genes have been found to be up-regulated under a combination of stressing conditions, including high temperature 8 , chilling 9 , osmotic stress and salinity 10 , water deficit 11 , and heavy metals 12 , among others. In addition, when overexpressed in transgenic plants, SAP genes confer tolerance to abiotic stresses 13–16 .…”

We have identified a gene (PpSAP1) of Prunus persica coding for a stress-associated protein (SAP) containing Zn-finger domains A20 and AN1. SAPs have been described as regulators of the abiotic stress response in plant species, emerging as potential candidates for improvement of stress tolerance in plants. PpSAP1 was highly expressed in leaves and dormant buds, being down-regulated before bud dormancy release. PpSAP1 expression was moderately induced by water stresses and heat in buds. In addition, it was found that PpSAP1 strongly interacts with polyubiquitin proteins in the yeast two-hybrid system. The overexpression of PpSAP1 in transgenic plum plants led to alterations in leaf shape and an increase of water retention under drought stress. Moreover, we established that leaf morphological alterations were concomitant with a reduced cell size and down-regulation of genes involved in cell growth, such as GROWTH-REGULATING FACTOR (GRF)1-like, TONOPLAST INTRINSIC PROTEIN (TIP)-like, and TARGET OF RAPAMYCIN (TOR)-like. Especially, the inverse expression pattern of PpSAP1 and TOR-like in transgenic plum and peach buds suggests a role of PpSAP1 in cell expansion through the regulation of TOR pathway.

“…However, plants overexpressing BBX24 (Yang et al, 2014) also showed reduced GA content, but plants expressing BBX24 showed normal growth phenotype and enhanced salt and drought stress tolerance (Yang et al, 2014). ZFPS are also involved in high temperature (Kim et al, 2015) and H + tolerance (Fan et al, 2015). Although many ZFPs regulate abiotic stress tolerance positively, some ZFPs regulate abiotic stress tolerance negatively.…”

Plant zinc finger proteins (ZFPs) comprise a large protein family and they are mainly involved in abiotic stress tolerance. Although Arabidopsis RING/FYVE/PHD ZFP At5g62460 (AtRZFP) is found to bind to zinc, whether it is involved in abiotic stress tolerance is still unknown. In the present study, we characterized the roles of AtRZFP in response to abiotic stresses. The expression of AtRZFP was induced significantly by salt and osmotic stress. AtRZFP positively mediates tolerance to salt and osmotic stress. Additionally, compared with wild-type Arabidopsis plants, plants overexpressing AtRZFP showed reduced reactive oxygen species (ROSs) accumulation, enhanced superoxide dismutase and peroxidase activity, increased soluble sugars and proline contents, reduced K+ loss, decreased Na+ accumulation, stomatal aperture and the water loss rate. Conversely, AtRZFP knockout plants displayed the opposite physiological changes when exposed to salt or osmotic stress conditions. These data suggested that AtRZFP enhances salt and osmotic tolerance through a series of physiological processes, including enhanced ROSs scavenging, maintaining Na+ and K+ homeostasis, controlling the stomatal aperture to reduce the water loss rate, and accumulating soluble sugars and proline to adjust the osmotic potential.
