“…Nuruzzaman et al [11] identified five OsWRKY genes expressed at higher levels in drought-tolerant rice compared with those in drought-susceptible rice under experimental water-deficit conditions. Overexpression of OsWRKY47 increased both the yield and drought tolerance compared with wild-type plants [12]. Meng et al [13] discovered that 10 selected WRKY genes showed differential expression patterns under waterlogging and drought stress in an apple rootstock.…”

Background: Sesame (Sesamum indicum L.) is one of the world's most important oil crops. However, it is susceptible to abiotic stresses in general, and to waterlogging and drought stresses in particular. The molecular mechanisms of abiotic stress tolerance in sesame have not yet been elucidated. The WRKY domain transcription factors play significant roles in plant growth, development, and responses to stresses. However, little is known about the number, location, structure, molecular phylogenetics, and expression of the WRKY genes in sesame.

“…When overexpressed in rice, OsbZIP23, OsbZIP46 and OsbZIP71 indicated a positive correlation with yield under drought by regulating the expression of dehydrins, membrane transporters like OsNHX1 and COR413-TM1, and ABFs (Xiang et al, 2008, Tang et al, 2012. Belonging to the GRAS family, OsGRAS23 was found to contribute to yield increase under drought through regulation of ROS scavenging (Raineri et al, 2015, Guo et al, 2016a.…”

“…Expression analysis of the WRKY family of TFs in rice identified OsWRKY45 and OsWRKY11 as heat inducible, while overexpression of OsWRKY11 under the control of HSP101 promoter showed tolerance to HTS indicated by higher survival rates and lower leaf wilting (Wu et al, 2009). OSWRKY47, MID1 (MYB Important for Drought Response1) were also found to contribute to drought tolerance and hence yield by modulating the expression of Calmodulin-Binding Protein (CaMBP) (Raineri et al, 2015, Guo et al, 2016a. Two ABA-inducible TFs: OsAREB1 and OsSNAC3 were also induced by heat, and when overexpressed in rice and Arabidopsis, the transgenic plants showed heat tolerance owing to efficient scavenging of ROS and regulation of genes from the ABA signaling pathway (Jin et al, 2010, Fang et al, 2015.…”

Rice production, owing to its high-water requirement for cultivation, is very vulnerable to the threat of changing climate, particularly prolonged drought and high temperature. Such threats heighten the need for abiotic stress-resilient rice varieties with better yield potential. This review examines the physiological and molecular mechanisms of rice varieties to cope with stress conditions of drought (DS), high temperature (HTS) and their combination (DS-HTS). It appraises research studies in rice about its various phenotypic traits, genetic loci and response mechanisms to stress conditions to help craft new breeding strategies for rice varieties with improved resilience to abiotic stresses. This review consolidates available information on promising rice cultivars with desirable traits as well as advocates synergistic and complementary approaches in molecular and systems biology to develop new rice breeds that favorably respond to climate-induced abiotic stresses. The development of new breeding and cultivation strategies for climate-resilient rice varieties is a challenging task. It requires a comprehensive understanding of the various morphological, biochemical, physiological, and molecular components governing yield under drought and high temperature, but possible by implementing cohesive approaches involving molecular and systems biology approaches in genomics and molecular breeding, including genetic engineering.

“…In rice, 11 OsWRKY genes showed variable responses to salt, polyethylene glycol (PEG), and cold or heat stresses [25]. Overexpression of OsWRKY47 increased both the drought tolerance and yield compared with wild-type plants [26]. In mulberry, Morus013217 and Morus002784 show high accumulation in response to cold and salt stresses.…”

Longan is an important fruit tree in the subtropical region of Southeast Asia and Australia. However, its blooming and its yield are susceptible to stresses such as droughts, high salinity, and high and low temperature. To date, the molecular mechanisms of abiotic stress tolerance and flower induction in longan have not been elucidated. WRKY transcription factors (TFs), which have been studied in various plant species, play important regulatory roles in plant growth, development, and responses to stresses. However, there is no report about WRKYs in longan. In this study, we identified 55 WRKY genes with the conserved WRKY domain and zinc finger motif in the longan genome. Based on the structural features of WRKY proteins and topology of the phylogenetic tree, the longan WRKY (DlWRKY) family was classified into three major groups (I–III) and five subgroups (IIa–IIe) in group II. Tissue expression analysis showed that 25 DlWRKYs were highly expressed in almost all organs, suggesting that these genes may be important for plant growth and organ development in longan. Comparative RNA-seq and qRT-PCR-based gene expression analysis revealed that 18 DlWRKY genes showed a specific expression during three stages of flower induction in “Sijimi” (“SJ”), which exhibited the “perpetual flowering” (PF) habit, indicating that these 18 DlWRKY genes may be involved in the flower induction and the genetic control of the perpetual flowering trait in longan. Furthermore, the RT-qPCR analysis illustrated the significant variation of 27, 18, 15, 17, 27, and 23 DlWRKY genes under SA (Salicylic acid), MeJA (Methyl Jasmonate), heat, cold, drought, or high salinity treatment, respectively, implicating that they might be stress- or hormone-responsive genes. In summary, we systematically and comprehensively analyzed the structure, evolution, and expression pattern of the DlWRKY genes. The results presented here increase our understanding of the WRKY family in fruit trees and provide a basis for the further elucidation of the biological function of DlWRKY genes in longan.
