“…Moreover, climate change and increased temperatures can be expected to promote further complications that will make general R genes more susceptible to the Xoo pathogen [ 23 , 24 ]. Durability of BB R genes such as Xa4 show decreased effectiveness in controlling BB disease at higher temperatures [ 25 ].…”

Xanthomonas oryzae pv. oryzae (Xoo) is a pathogen that has ravaged the rice industry as the causal agent of bacterial blight (BB) diseases in rice. Koshihikari (KO), an elite japonica cultivar, and ARC7013 (AR), an indica cultivar, are both susceptible to Xoo. Their phenotypic characteristics reveal that KO has shorter lesion length than that of AR. The F2 population from KO × AR results in continuous distribution of lesion length by inoculation of an Xoo race (T7147). Consequently, quantitative trait loci (QTL) mapping of the F2 population is conducted, covering 12 chromosomes with 107 simple sequence repeat (SSR) and insertion/deletion (InDel) genetic markers. Three QTLs are identified on chromosomes 2, 5, and 10. Of them, qXAR5 has the strongest resistance variance effect of 20.5%, whereas qXAR2 and qXAR10 have minor QTL effects on resistance variance, with 3.9% and 2.3%, respectively, for a total resistance variance of 26.7%. The QTLs we examine for this study differ from the loci of BB resistance genes from earlier studies. Our results can help to facilitate understanding of genetic and morphological fundamentals for use in rice breeding programs that are more durable against evolving Xoo pathogens and uncertain climatic temperature.

“…Differential dynamics of the regulatory network topology showed that ERFs (e.g., ERF104, ERF83, ERF91, ERF118, and ERF47) play a crucial role during signal crosstalk in rice plants responding to Xanthomonas oryzae pv. oryzae , the causal agent of bacterial leaf blight disease, under high or low temperature [ 54 ]. OsEREBP1, phosphorylated by OsMPK12, exhibited enhanced binding to the GCC box element of defense gene promoters [ 55 ], and overexpression of OsEREBP1 enhanced resistance against X. oryzae pv.…”

“…OsEREBP1 and OsEREBP2 negatively regulate the expression of OsRMC , encoding a receptor-like kinase that is a negative regulator of salt stress responses in rice [ 88 ]. Some rice OsERF genes, such as OsDREB1s , OsEREBP1 , OsSTAP1 and OsAP25 , were reported to be induced under low temperature or cold stress conditions [ 46 , 54 , 64 , 86 , 88 , 89 , 90 , 91 ], and overexpression of OsDREB1A , OsDREB1F or OsDREB1G in transgenic rice increased tolerance to cold or low-temperature stress [ 66 , 90 , 92 ]. Recently, it was found that the overexpression of OsERF115 conferred enhanced heat tolerance in transgenic rice plants [ 78 ].…”

We previously showed that overexpression of the rice ERF transcription factor gene OsBIERF3 in tobacco increased resistance against different pathogens. Here, we report the function of OsBIERF3 in rice immunity and abiotic stress tolerance. Expression of OsBIERF3 was induced by Xanthomonas oryzae pv. oryzae, hormones (e.g., salicylic acid, methyl jasmonate, 1-aminocyclopropane-1-carboxylic acid, and abscisic acid), and abiotic stress (e.g., drought, salt and cold stress). OsBIERF3 has transcriptional activation activity that depends on its C-terminal region. The OsBIERF3-overexpressing (OsBIERF3-OE) plants exhibited increased resistance while OsBIERF3-suppressed (OsBIERF3-Ri) plants displayed decreased resistance to Magnaporthe oryzae and X. oryzae pv. oryzae. A set of genes including those for PRs and MAPK kinases were up-regulated in OsBIERF3-OE plants. Cell wall biosynthetic enzyme genes were up-regulated in OsBIERF3-OE plants but down-regulated in OsBIERF3-Ri plants; accordingly, cell walls became thicker in OsBIERF3-OE plants but thinner in OsBIERF3-Ri plants than WT plants. The OsBIERF3-OE plants attenuated while OsBIERF3-Ri plants enhanced cold tolerance, accompanied by altered expression of cold-responsive genes and proline accumulation. Exogenous abscisic acid and 1-aminocyclopropane-1-carboxylic acid, a precursor of ethylene biosynthesis, restored the attenuated cold tolerance in OsBIERF3-OE plants while exogenous AgNO3, an inhibitor of ethylene action, significantly suppressed the enhanced cold tolerance in OsBIERF3-Ri plants. These data demonstrate that OsBIERF3 positively contributes to immunity against M. oryzae and X. oryzae pv. oryzae but negatively regulates cold stress tolerance in rice.

“…Since the past decade, along with experimental analysis, scientists have been using high-throughput omic approaches to understand the systemic complexity and gain mechanistic insights of plants during stress conditions [ 13 ]. The transcriptomic approach for studying the expression and regulation of coding regions of the plant genome in response to different stress conditions has aided in capturing significant information on stress resistance genes and transcription factors [ 14 , 15 ]. Transcriptomic study of maize during single heat stress has identified 167 putative transcription factors belonging to different TF families like myeloblastosis (MYB), apetala2-ethylene responsive element binding protein (AP2-EREBP), basic leucine zipper (b-ZIP), basic helix loop helix (bHLH), NAC , and WRKY (a TF family renamed with singlet codes of tryptophan, arginine, lysine, and tyrosine) [ 16 ].…”

Combined stress has been seen as a major threat to world agriculture production. Maize is one of the leading cereal crops of the world due to its wide spectrum of growth conditions and is moderately sensitive to salt stress. A saline soil environment is a major factor that hinders its growth and overall yield and causes an increase in the concentration of micronutrients like boron, leading to excess over the requirement of the plant. Boron toxicity combined with salinity has been reported to be a serious threat to the yield and quality of maize. The response signatures of the maize plants to the combined effect of salinity and boron stress have not been studied well. We carried out an integrative systems-level analysis of the publicly available transcriptomic data generated on tolerant maize (Lluteño maize from the Atacama Desert, Chile) landrace under combined salt and boron stress. We identified significant biological processes that are differentially regulated in combined salt and boron stress in the leaves and roots of maize, respectively. Protein-protein interaction network analysis identified important roles of aldehyde dehydrogenase (ALDH), galactinol synthase 2 (GOLS2) proteins of leaf and proteolipid membrane potential regulator (pmpm4), metallothionein lea protein group 3 (mlg3), and cold regulated 410 (COR410) proteins of root in salt tolerance and regulating boron toxicity in maize. Identification of transcription factors coupled with regulatory network analysis using machine learning approach identified a few heat shock factors (HSFs) and NAC (NAM (no apical meristem, Petunia), ATAF1–2 (Arabidopsis thaliana activating factor), and CUC2 (cup-shaped cotyledon, Arabidopsis)) family transcription factors (TFs) to play crucial roles in salt tolerance, maintaining reactive oxygen species (ROS) levels and minimizing oxidative damage to the cells. These findings will provide new ways to design targeted functional validation experiments for developing multistress-resistant maize crops.
