Contemporary climatic stress seriously affects rice production. Unfortunately, long-term domestication and improvement modified the phytohormones network to achieve production needs of cultivated rice, thus leading a decrease in adaptation. Here, we identify 14-3-3 protein-coding gene OsGF14h weedy that confers anaerobic germination seedling development tolerance. acts as signal switch balance ABA signaling GA biosynthesis by interacting with transcription factors OsHOX3 OsVP1, thereby...
Abstract Flowering time is one of the most important agronomic traits affecting adaptation and yield rice (Oryza sativa). Heading date 1 (Hd1) a key factor in photoperiodic control flowering time. In this study, two basic helix-loop-helix (bHLH) transcription factors, Hd1 Binding Protein (HBP1) Partner HBP1 (POH1) were identified as transcriptional regulators Hd1. We generated knockout mutants ectopically expressed transgenic lines bHLH factors used these to investigate roles regulating...
Although recent studies have suggested that the microfilament (MF) cytoskeleton of plant cells participates in response to salt stress, it remains unclear as whether MF actually plays an active role a plant's ability withstand stress. In present study, we report for first time MFs tolerance Arabidopsis thaliana. Our experiments revealed seedlings treated with 150 mm NaCl maintained assembly and bundle formation, whereas treatment 250 initially induced but subsequently caused disassembly. A...
Similar to other eukaryotes, splicing is emerging as an important process affecting development and stress tolerance in plants. Ski-interacting protein (SKIP), a factor, essential for circadian clock function abiotic tolerance; however, the mechanisms whereby it regulates flowering time are unknown. In this study, we found that SKIP required of serrated leaves early (SEF) pre-messenger RNA (mRNA), which encodes component ATP-dependent SWR1 chromatin remodeling complex (SWR1-C). Defects SEF...
Abstract Tiller angle is a key factor determining rice plant architecture, planting density, light interception, photosynthetic efficiency, disease resistance and grain yield. However, the mechanisms underlying tiller control are far from clear. In this study, we identified mutant, termed bta1-1, with an enlarged throughout its life cycle. A detailed analysis reveals that BTA1 has multiple functions because angle, shoot gravitropism tolerance to drought stress changed in bta1-1 plants....
The prevalence of soluble aluminum (Al) ions is one the major limitations to crop production worldwide on acid soils. Therefore, understanding Al tolerance mechanism rice and applying functional genes in sensitive plants can significantly improve stress resistance. In this study, transcriptomics metabolomics analyses were performed reveal differences between two landraces (Al-tolerant genotype Shibanzhan (KR) Al-sensitive Hekedanuo (MR) with different tolerance. results showed that DEG...
Abscisic acid (ABA) plays key roles in plant development and responses to abiotic stresses. A wide number of transcriptional posttranslational regulatory mechanisms ABA signaling are known; however, less is known about the alternative splicing. In this work, we found that SKIP, a splicing factor, positively regulates signaling. SKIP binds pre-mRNA signaling-related genes, such as PYL7, PYL8, ABI1, HAB1 ABI5, regulate their The precursor mRNA several PYL receptors, PP2C phosphatases ABF...
Rice breeders are now developing new varieties with semi-high or even high plant height to further increase the grain yield, and problem of lodging has re-appeared. We identified a major quantitative trait locus (QTL), qSCM4, for resistance by using an F2 segregant population recombinant self-incompatible line from cross between Shennong265 (SN265) Lijiangxintuanheigu (LTH) after multiple years environments. Then, residual heterozygous derived which consisted 1781 individual plants, BC3F2...
Abstract Rice (Oryza sativa L.) is a cold-sensitive species that often faces cold stress, which adversely affects yield productivity and quality. However, the genetic basis for low-temperature adaptation in rice remains unclear. Here, we demonstrate 2 functional polymorphisms O. SEC13 Homolog 1 (OsSEH1), encoding WD40-repeat nucleoporin, between subspecies japonica indica rice, may have facilitated rice. We show OsSEH1 of variety expressed OsSEH1MSD plants (transgenic line overexpressing...
Cold stress (CS) significantly impacts rice (Oryza sativa L.) growth during seedling and heading stages. Based on two-year field observations, this study identified two lines, L9 (cold stress-sensitive) LD18 stress-tolerant), showing contrasting CS responses. exhibited a 38% reduction in photosynthetic efficiency, whereas remained unchanged, correlating with seed rates. Transcriptome analysis differentially expressed genes (DEGs) enriched pathways (carbon fixation, starch/sucrose metabolism,...
The development of efficient non-precious metal electrocatalysts for the oxygen evolution reaction (OER) is crucial addressing pressing challenges energy and environmental sustainability. In this study, we employed...
Grain filling influences grain size and quality in cereal crops. The molecular mechanisms that regulate endosperm development remain elusive. In this study, we characterized a filling-defective width mutant, fgw1, whose mutation increased rice seed mainly via cell division expansion grains. Sucrose contents were higher but starch lower the fgw1 mutant during grain-filling stage, resulting inferior of opaque, white appearance with loosely packed granules. Map-based cloning revealed FGW1...
Mesocotyl elongation in rice is essential for seedling emergence. Our previous screening identified two weedy accessions (Oryza sativa f. spontanea L.) (WR04-6 and WR04-43) were with unusually long mesocotyl. In this study, using cultivar (Nipponbare, Oryza L., subspecies temperate japonica) as a control, we found that at the middle end of mesocotyl elongation, predominant cortical microtubules (CMTs) are transversely oriented related to cell while, cultivated had oblique MT arrays....
The production of japonica rice in northern China plays an important role food security for the world. Agrobacterium-mediated gene transfer is becoming a powerful approach to generate germplasm and develop varieties. However, transgenic efficiency varieties has been completely unknown, which obstructs development breeding exploration functions. In this study, efficiencies six developed are evaluated. rates primary secondary callus induction similar. regeneration ability greatly different....
Sheath blight (ShB) caused by Rhizoctonia solani is a major disease of rice, seriously affecting yield; however, the molecular defense mechanism against ShB remains unclear. A previous transcriptome analysis rice identified that R. inoculation significantly induced MDPK. Genetic studies using MDPK RNAi and overexpressing plants positively regulates resistance. This protein was found localized in endoplasmic reticulum (ER) Golgi apparatus. Yeast one-hybrid assay, electrophoresis mobility...
Tillering is an important agronomic trait of rice (Oryza sativa) that affect the number seffective panicle, thereby affecting yields. The phytohormone auxin plays a key role in tillering. Here we identified high tillering and semi-dwarf 1 (htsd1) mutant, whose roots exhibit auxin-deficiency characteristics, such as shortened lateral roots, reduced root density, enlarged angles. htsd1 showed sensitivity to auxin, but external application inhibited its We mutated gene AUXIN1 (OsAUX1,...
The trichomes of rice leaves are formed by the differentiation and development epidermal cells. Plant play an important role in stress resistance protection against direct ultraviolet irradiation. However, remains poorly understood. In this study, we conducted ethylmethane sulfonate (EMS)-mediated mutagenesis on wild-type (WT) indica 'Xida 1B'. Phenotypic analysis led to screening a mutant that is defective trichome development, designated lhl1 (less hairy leaf 1). We performed map-based...

Abstract Grain filling is a crucial trait that influences grain size and quality in cereal crops. However, the molecular mechanisms regulate endosperm development remain elusive. In this study, we characterize filling-defective width mutant fgw1 , which increased rice seed mainly by influencing cell division expansion glumes. Sucrose contents were higher, whereas starch lower, during grain-filling stage, resulted inferior of opaque, white appearance with loosely packed granules. Map-based...
