Glutathione S-transferases (GSTs) are well-known enzymes due to their role in detoxification of xenobiotic compounds. However, their biochemical action is still not so clear in imparting tolerance to several abiotic stresses in crop plants. In our previous study, we observed that rice tau class OsGSTU30 plays a significant role in the detoxification of Cr(vi). Interestingly, q-RT PCR analysis also revealed higher expression of OsGSTU30 under drought conditions. In this study, we characterize OsGSTU30 in response to drought as well as heavy metal [Cr(vi)] stresses through overexpression in Arabidopsis thaliana...

BACKGROUND: The glycogen synthase kinase 3/shaggy kinase (GSK3) is a serine/threonine kinase with important roles in animals. Although GSK3 genes have been studied for more than 30 years, plant GSK genes have been studied only since the last decade. Previous research has confirmed that plant GSK genes are involved in diverse processes, including floral development, brassinosteroid signaling, and responses to abiotic stresses. RESULT: In this study, 20, 15 (including 5 different transcripts) and 10 GSK genes were identified in G...

Ricefield flatsedge ( Cyperus iria L.), a troublesome weed in rice production, actively adapts to ecological niches. In this study, terpenoids were identified as the dominant compounds from organic extracts of C. iria leaves. To understand the role of terpenoid production in plant development and resistance to abiotic and biotic stresses, the dynamics of terpenoid production at different developmental stages, and the regulation of these compounds by stresses were determined. Terpenoid production exhibited temporal and spatial specificity...

Khao Dawk Mali 105 (KDML105) rice is one of the most important crops of Thailand. It is a challenging task to identify the genes responding to salinity in KDML105 rice. The analysis of the gene co-expression network has been widely performed to prioritize significant genes, in order to select the key genes in a specific condition. In this work, we analyzed the two-state co-expression networks of KDML105 rice under salt-stress and normal grown conditions. The clustering coefficient was applied to both networks and exhibited significantly different structures between the salt-stress state network and the original (normal-grown) network...

The plant-specific TCP transcription factors, which play critical roles in diverse aspects of biological processes, have been identified and analyzed in various plant species. However, no systematical study of TCP family genes in potato (Solanum tuberosum L.) has been undertaken. In this study, a total of 31 non-redundant TCP transcription factors of potato were identified and divided into two subfamilies including three distinct subclades. The various orthologous TCP genes in Arabidopsis, rice, potato and tomato were identified using synteny and phylogenetic analysis...

Abiotic stresses like drought are detrimental for growth and development and lead to loss in crop production. To be able to adapt and survive under such adverse conditions, synchronous regulation of a rather large number of genes is required. Here, we have used a bioinformatics approach to identify gene groups and associated pathways from microarray and RNA-seq experiments that are restricted in their gene expression amplitude within fold change intervals (FCIs) under drought stress conditions. We find that the expression of genes as functional groups is coordinated quantitatively, in a fold change specific manner, and differs among three rice cultivars distinct in their drought stress response...

Silicon (Si) enhances the resistance of rice to biotic and abiotic stress. In rice, the accumulation of Si is controlled by the low silicon rice 1 (Lsi1) gene; overexpression of Lsi1 (Lsi1-OX) increases Si uptake and accumulation, while the reverse is observed in Lsi1-RNA interference (Lsi1-RNAi) transgenic rice. When the two transgenic rice lines and wild-type (WT) rice were exposed to ultraviolet (UV)-B radiation, the Lsi1-OX or Lsi1-RNAi rice showed differential microRNA (miRNA) expression, compared to WT rice...

Environmental stresses are the major factors that limit the geographical distribution of plants. As a consequence, plants have developed different strategies to adapt to these environmental changes among which can be outlined the maintenance of membranes' integrity and fluidity. Lipids are key molecules for this environmental adaptation and a comprehensive understand of the molecular mechanisms underlying is still required. Here, lipidome changes in Japanese rice (Oryza sativa var. Japonica) upon heat and hydric stresses are assessed using an untargeted approach based on liquid chromatography coupled with mass spectrometry (LC-MS)...

In cereal crops, ABA deficiency during seed maturation phase causes pre-harvest sprouting (PHS), and molybdenum cofactor (MoCo) is required for ABA biosynthesis. Here, two rice PHS mutants F254 and F5-1 were characterized. In addition to the PHS, these mutants showed pleiotropic phenotypes such as twisting and slender leaves, and then died when the seedling developed to four or five leaves. Map-based cloning showed that OsCNX6 and OsCNX1 encoding homologs of MoaE and MoeA were responsible for F254 and F5-1 mutants, respectively...

OsMADS27 is one of the ANR1-like homologues in rice, whreas its functions in plant growth and development as well as the abiotic stress responses remain unclear. Here we investigated the roles of OsMADS27 in the root development in response to NO3 - availability. Constitutive expression of OsMADS27 significantly inhibited the elongation of primary root (PR), but enhanced lateral root (LR) formation in a NO3 --dependent manner. Furthermore, OsMADS27 overexpression promoted NO3 - accumulation as well as the expression of NO3 - transporter genes...

Expression of the Galactinol synthase genes in rice is regulated through post-transcriptional intron retention in response to abiotic stress and may be linked to Raffinose Family Oligosaccharide synthesis in osmotic perturbation. Galactinol synthase (GolS) is the first committed enzyme in raffinose family oligosaccharide (RFO) synthesis pathway and synthesizes galactinol from UDP-galactose and inositol. Expression of GolS genes has long been implicated in abiotic stress, especially drought and salinity. A non-canonical regulation mechanism controlling the splicing and maturation of rice GolS genes was identified in rice photosynthetic tissue...

Cultivated rice (Oryza sativa) originated from common wild rice (Oryza rufipogon) and inherited its advantages. However, during the rice domestication process, some valuable features of wild rice, such as tolerance to biotic and abiotic stress, were lost. To fully utilize wild rice germplasm resources, we constructed a set of introgression lines (ILs) using a common wild rice material from Lingshui, China. A set of high-resolution InDel molecular markers with an average interval of 2.39 Mb were designed to carry out marker-assisted selection and identification of segment characteristics...

The protein elicitor PeaT1 was found in Alternaria tenuissima and exerted broad spectrum resistance in wheat, cotton, and rice. Recently, we found that overexpressing PeaT1 rice (OE) could enhance plant drought tolerance. Elucidating some elevated drought stress-related proteins and associated mechanisms is inevitable for improving drought tolerance in rice. In this study, combining a label-free quantitative proteomic method, multiple proteins were differentially accumulated in OE plants. Among these, a total of 57 significant changed proteins (including 32 up-regulated and 25 down-regulated) were mainly involved in metabolic, cellular, biological progress, and stress response...

Drought is a major abiotic stress that reduces rice development and yield. miRNAs (microRNAs) are known to mediate posttranscriptional regulation under drought stress. Although the importance of individual miRNAs has been established, the crosstalks between miRNAs and mRNAs remain unearthed. Here we performed microarray analysis of miRNAs and matched mRNA expression profiles of drought-treated rice cultivar Nipponbare. Drought-responsive miRNA-mRNA regulations were identified by a combination of a partial least square (PLS) regression approach and sequence-based target prediction...

Weedy rice is an important germplasm resource for rice improvement because it has useful genes for many abiotic stresses including cold tolerance. We identified the cold tolerance and cold sensitivity of two weedy rice lines (WR 03-35 and WR 03-26) and two cultivated rice lines (Kongyu 131 and 9311). During the seedling stage of these lines, we used RNA-seq to measure changes in weedy rice and cultivated rice whole-genome transcriptome before and after cold treatment. We identified 14,213 and 14,730 differentially expressed genes (DEGs) in cold-tolerant genotypes (WR 03-35, Kongyu 131), and 9219 and 720 DEGs were observed in two cold-sensitive genotypes (WR 03-26, 9311)...

Mitogen-activated protein kinase (MAPK) cascades are fundamental signal transduction modules in all eukaryotic organisms, controlling cell division, growth, development, and hormone signaling. Additionally, they can be activated in response to a variety of biotic and abiotic stressors. Although the evolution and expression patterns of MAPK cascade families have been systematically investigated in several model plants (e.g., Arabidopsis, rice, and poplar), we still know very little about MAPK, MAPKK, and MAPKKK families in Jatropha curcas, an economically important species...

BACKGROUND: WRKY proteins are one of the largest gene families and are well-known for their regulatory roles in many aspects of plant development, including plant response to both biotic and abiotic stresses. Although the roles of WRKY proteins in leaf blast resistance have been well-documented in rice, their functions in panicle blast, the most destructive type of blast disease, are still largely unknown. RESULTS: Here, we identified that the transcription of OsWRKY67 was strongly activated by leaf and panicle blast infection...

In India, rice is the principal crop and is the staple diet of majority of the population. Widespread use of hexavalent chromium [Cr(VI)] in leather processing, wood preservatives, stainless-steel manufacture, and electroplating industries has resulted in contamination of paddy fields and poses a great challenge to the society be it crops, animals, or human beings. Cr(VI) toxicity results in growth inhibition and leading to changes in components of antioxidant systems as well as secondary metabolites. We evaluated the comparative short and long term effects of Cr(VI) stress on rice plants to explore the plant defense responses against Cr stress...

Leaf rolling is one of the most significant symptoms of drought stress in plant. Previously, we identified a dominant negative mutant, termed rolled and erect 1 (hereafter referred to rel1-D), regulating leaf rolling and erectness in rice. However, the role of REL1 in drought response is still poorly understood. Here, our results indicated that rel1-D displayed higher tolerance to drought relative to wild type, and the activity of superoxide dismutase (SOD) and drought responsive genes were significantly up-regulated in rel1-D...
