Abstract The indica and japonica rice ( Oryza sativa ) subspecies differ in nitrate (NO 3 − assimilation capacity nitrogen (N) use efficiency (NUE). Here, we show that a major component of this difference is conferred by allelic variation at OsNR2 , gene encoding NADH/NADPH-dependent NO reductase (NR). Selection-driven divergence has resulted variant alleles structurally distinct proteins, with exhibiting greater NR activity. Indica also promotes uptake via feed-forward interaction OsNRT1.1B...
Abstract As an important agronomic trait, rice (Oryza sativa L.) leaf rolling has attracted much attention from plant biologists and breeders. Moderate increases the photosynthesis of cultivars hence raises grain yield. However, relevant molecular mechanism remains unclear. Here, we show isolation functional characterization SHALLOT-LIKE1 (SLL1), a key gene controlling rolling. sll1 mutant plants have extremely incurved leaves due to defective development sclerenchymatous cells on abaxial...
Significance Hybrid rice developed in China has been contributing greatly to the world’s food production. The pioneer super hybrid by crossing 93–11 and Peiai 64s , Liang–You–Pei–Jiu widely grown other Asia-Pacific regions for its high yield. Here, quality genome sequences both parental lines were presented updated, a high-resolution map of genome-wide graphic genotypes was constructed deep resequencing core population 132 recombinant inbred lines. A series yield-associated loci fine-mapped,...
The basic premise of high yield in rice is to improve leaf photosynthetic efficiency and coordinate the source–sink relationship plants. Quantitative trait loci (QTLs) related morphological traits chlorophyll content leaves were detected at stages heading maturity, a major QTL (qLSCHL4) flag shape was both recombinant inbred lines constructed using indica cultivar 93-11 japonica Nipponbare. Map-based cloning expression analysis showed that LSCHL4 allelic NAL1, gene previously reported narrow...
Abstract Leaf rolling is an important agronomic trait in rice (Oryza sativa) breeding and moderate leaf maintains the erectness of leaves minimizes shadowing between leaves, leading to improved photosynthetic efficiency grain yields. Although a few rolled-leaf mutants have been identified some genes controlling isolated, molecular mechanisms still need be elucidated. Here we report isolation characterization SEMI-ROLLED LEAF1 (SRL1), gene involved regulation rolling. Mutants srl1-1 (point...
Chlorophyll (Chl) b is a ubiquitous accessory pigment in land plants, green algae, and prochlorophytes. This synthesized from Chl by chlorophyllide oxygenase plays key role adaptation to various environments. study characterizes rice mutant, pale leaf (pgl), isolates the gene PGL using map-based cloning approach. PGL, encoding 1, mainly expressed chlorenchyma activated light-dependent synthesis process. Compared with wild-type pgl exhibits lower content reduced disorderly thylakoid...
Understanding the genetic basis of natural variation in grain size among diverse rice varieties can help breeders develop high-yielding cultivars. Here, we report discovery qTGW2, a new semidominant quantitative trait locus for width and weight. The corresponding gene, TGW2, encodes CELL NUMBER REGULATOR 1 (OsCNR1) localized to plasma membrane. A single nucleotide polymorphism (SNP) 1818 bp upstream TGW2 is responsible its different expression, leading alteration weight by influencing cell...
Summary Lesion‐mimic mutants (LMMs) provide a valuable tool to reveal the molecular mechanisms determining programmed cell death (PCD) in plants. Despite intensive research, behind PCD and formation of lesions various LMMs still remain be elucidated. Here, we identified rice ( Oryza sativa ) LMM, early lesion leaf 1 ell1 ), cloned causal gene by map‐based cloning, verified this complementation. ELL1 encodes cytochrome P450 monooxygenase, protein was located endoplasmic reticulum. The mutant...
Abstract Background Abscisic acid (ABA) acts as a signaling hormone in plants against abiotic stress, but its function energy homeostasis under heat stress is unclear. Results Two rice genotypes, Nipponbare (wild-type, WT) with flat leaves and mutant high temperature susceptibility ( hts ) plant semi-rolled leaves, were subjected to stress. We found significantly higher tissue temperature, respiration rate, ABA H 2 O contents well lower transpiration rate stomatal conductance than WT plants....
Increasing tiller number is a target of high-yield rice breeding. Identification tiller-defect mutants and their corresponding genes helpful for clarifying the molecular mechanism tillering. Summarizing research progress on two processes formation, namely formation growth axillary meristem, this paper reviews effects genetic factors, endogenous hormones, exogenous environment tillering, finding that multiple mechanisms signal pathways regulating tillering cooperate discusses future...
Summary Plant architecture and stress tolerance play important roles in rice breeding. Specific leaf morphologies ideal plant can effectively improve both abiotic resistance grain yield. However, the mechanism by which plants simultaneously regulate morphogenesis remains elusive. Here, we report that SRL10 , encodes a double‐stranded RNA‐binding protein, regulates morphology thermotolerance through alteration of microRNA biogenesis. The srl10 mutant had semi‐rolled phenotype elevated...
Carotenoid isomerase activity and carotenoid content maintain the appropriate tiller number, photosynthesis, grain yield. Interactions between strigolactone abscisic acid pathways regulates formation. Tillers are unique inflorescence-like branches in grasses, their number determines panicle plant architecture, yield (Shang et al., 2021). Tiller formation mainly undergoes axillary meristem (AM) initiation bud outgrowth (Wang 2018; Yan 2023). The rice (Oryza sativa) KNOX gene OSH1 is expressed...
To better understand the molecular mechanisms behind plant growth and leaf senescence in monocot plants, we identified a mutant exhibiting dwarfism an early-senescence phenotype, termed dwarf leaf1 (del1). Histological analysis showed that abnormal was caused by reduction cell number. Further investigation revealed decline number del1 affected cycle. Physiological analysis, transmission electron microscopy, TUNEL assays triggered accumulation of reactive oxygen species. The DEL1 gene cloned...
Flag leaf is the most essential organ for photosynthesis in rice and its size plays an important role breeding ideal plant-type. affect to a certain extent, thereby influencing production. Several genes controlling shape have been identified with mutants. Although number of quantitative trait loci (QTLs) detected on 12 chromosomes different populations rice, few them were cloned.The pair-wise correlation analysis was conducted length, width length-width ratio flag leaf, yield per plant core...

The development of rice cultivars with improved nitrogen use efficiency (NUE) is desirable for sustainable agriculture. Achieving this goal depends in part on understanding how responds to low soil (N) and identifying causative genes underlying trait. To identify quantitative trait loci (QTL) or associated N response, we conducted a genome-wide association study (GWAS) using diverse panel 230 accessions performed transcriptomic investigation differential responses stress at two levels. We...
