“…Transgenic plants overexpressing OsMSR15 show hypersensitivity to exogenous ABA. Transgenic plants also showed increased expressions of a number of stressresponsive genes, including RD29A and DREB1A under drought stress, which suggested that OsMSR15 may play important roles in response to drought stress both in ABAdependent and -independent pathways (Zhang et al, 2016c). In the ZAT18 overexpression lines, RNA-seq analysis revealed the enrichment of pathways, such as hormone metabolism, stress response, and signaling pathways; stress-related genes, such as COR47, ERD7, LEA6, RAS1, and hormone-signaling-transduction-related genes, such as JAZ7 and PYL5, appear to be the downstream target genes of ZAT18 (Yin et al, 2017).…”

“…C2H2-type zinc finger proteins with EAR motifs play important roles in regulating abiotic-stress-related gene expression under conditions such as salt, drought, and low temperature (Han and Fu, 2019). The DLNL sequence (DLNbox) at the C-terminus of STZ, with trans-activation activity, functions in the transcriptional activation of DREB1A under salt stress (Sakamoto et al, 2004;Kazan, 2006;Zhang et al, 2016c;Li et al, 2018), while the DLN-box is not the only domain that determines the transcriptional inhibitory activity of C2H2 zinc finger proteins (Huang et al, 2009a).…”

“…The overexpression lines exhibit enhanced expression of stress-related genes, such as Oslea3, OsP5CS, and OsProT, which contribute to the accumulation of osmotic substances (Xu et al, 2008). Overexpressing OsMSR15 (Zhang et al, 2016c) and ZFP3 in transgenic Arabidopsis (Zhang et al, 2016a) confers increase in drought tolerance by maintaining higher proline contents, reducing electrolyte leakage, and increasing stress-responsive gene expression.…”

Abiotic stresses such as drought and salinity are major environmental factors that limit crop yields. Unraveling the molecular mechanisms underlying abiotic stress resistance is crucial for improving crop performance and increasing productivity under adverse environmental conditions. Zinc finger proteins, comprising one of the largest transcription factor families, are known for their finger-like structure and their ability to bind Zn 2+ . Zinc finger proteins are categorized into nine subfamilies based on their conserved Cys and His motifs, including the Cys2/His2-type (C2H2), C3H, C3HC4, C2HC5, C4HC3, C2HC, C4, C6, and C8 subfamilies. Over the past two decades, much progress has been made in understanding the roles of C2H2 zinc finger proteins in plant growth, development, and stress signal transduction. In this review, we focus on recent progress in elucidating the structures, functions, and classifications of plant C2H2 zinc finger proteins and their roles in abiotic stress responses.

“…To facilitate the analysis and molecular characterization of the regulatory network of stress-related genes in rice, we carried out a microarray-based study of global genome expression profiles of a male-sterile indica cultivar, Pei’ai 64 S (PA64S), subjected to cold, heat or drought stresses using Affymetrix GeneChip ® arrays22232425. The analysis of microarray data showed that many genes were up- and down-regulated by different stresses in the rice genome (unpublished data).…”

Abiotic stress seriously affects the yield of rice (Oryza sativa L.). Grain yield in rice is multiplicatively determined by the number of panicles, number of grains per panicle, and grain weight. Here, we describe the molecular and functional characterization of STRESS_tolerance and GRAIN_LENGTH (OsSGL), a rice gene strongly up-regulated by a wide spectrum of abiotic stresses. OsSGL encodes a putative member of the DUF1645 protein family of unknown function. Overexpression of OsSGL significantly altered certain development processes greatly and positively affecting an array of traits in transgenic rice plants, including increased grain length, grain weight and grain number per panicle, resulting in a significant increase in yield. Microscopical analysis showed that the enhanced OsSGL expression promoted cell division and grain filling. Microarray and quantitative real-time PCR (qRT-PCR) analyses revealed that a large number of genes involved in stress-response, cell cycle and cytokinin signaling processes were induced or suppressed in OsSGL-overexpressing plants. Together, our results suggest that OsSGL may regulate stress-tolerance and cell growth by acting via a cytokinin signaling pathway. This study not only contributes to our understanding of the underlying mechanism regulating rice stress-tolerance and grain length, but also provides a strategy for tailor-made crop yield improvement.

“…OsHBP1b belongs to bZIP family of transcription factors that activates ROS detoxification system and increases the content of protective molecules (i.e., soluble sugars and proline) under stressed conditions. A putative H 2 O 2 and ABA-responsive C 2 H 2 -type zinc finger protein OsMSR15 (Oryza sativa multi-stress-responsive protein) has been also identified in rice that enhances drought and oxidative stress tolerance via elevating antioxidant activities and ABA sensitivity (Zhang et al 2016). The biological role of another plant-specific protein-GRAS protein family (Gibberellic Acid Insensitive GAI, Repressor of GAI, and SCARECROW, acting as bZIP transcription factors) in conferring abiotic stress tolerance in rice has been also explicated recently; enhanced expression of OsGRAS23 in transgenic rice resulted in high drought as well oxidative stress resilience via reducing H 2 O 2 accumulation (Xu et al 2015).…”

Drought and heat stress-related proteins: an update about their functional relevance in imparting stress tolerance in agricultural crops

Key message We describe here the recent developments about the involvement of diverse stress-related proteins in sensing, signaling, and defending the cells in plants in response to drought or/and heat stress. Abstract In the current era of global climate drift, plant growth and productivity are often limited by various environmental stresses, especially drought and heat. Adaptation to abiotic stress is a multigenic process involving maintenance of homeostasis for proper survival under adverse environment. It has been widely observed that a series of proteins respond to heat and drought conditions at both transcriptional and translational levels. The proteins are involved in various signaling events, act as key transcriptional activators and saviors of plants under extreme environments. A detailed insight about the functional aspects of diverse stress-responsive proteins may assist in unraveling various stress resilience mechanisms in plants. Furthermore, by identifying the metabolic proteins associated with drought and heat tolerance, tolerant varieties can be produced through transgenic/recombinant technologies. A large number of regulatory and functional stress-associated proteins are reported to participate in response to heat and drought stresses, such as protein kinases, phosphatases, transcription factors, and late embryogenesis abundant proteins, dehydrins, osmotins, and heat shock proteins, which may be similar or unique to stress treatments. Few studies have revealed that cellular response to combined drought and heat stresses is distinctive, compared to their individual treatments. In this review, we would mainly focus on the new developments about various stress sensors and receptors, transcription factors, chaperones, and stress-associated proteins involved in drought or/ and heat stresses, and their possible role in augmenting stress tolerance in crops.
