Tillering and panicle branching are important determinants of plant architecture yield potential in rice (Oryza sativa). IDEAL PLANT ARCHITECTURE1 (IPA1) encodesSQUAMOSA PROMOTER BINDING PROTEIN-LIKE14, which acts as a key transcription factor regulating tiller outgrowth by directly activating the expression O. sativa TEOSINTE BRANCHED1 (OsTB1) DENSE AND ERECT PANICLE1 (OsDEP1), thereby influencing grain rice. Here, we report identification mutant named shi1 that is characterized...
Decreased PFPase activity in rice perturbs the equilibration of carbon metabolism during grain filling but has no visible phenotypic effects vegetative and reproductive growth stages. Starch is a primary energy reserve for various metabolic processes plant. Despite much advance been achieved pathways involved starch biosynthesis, information was still lacked precise regulation related to seed (Oryza sativa). The objective this study identify characterize new gene associated with filling. By...
Thioredoxins (TRXs) occur in plant chloroplasts as complex disulphide oxidoreductases. Although many biological processes are regulated by thioredoxins, the regulatory mechanism of chloroplast TRXs largely unknown. Here we report a rice white panicle2 mutant caused mutation thioredoxin z gene, an orthologue AtTRX Arabidopsis. (wp2) seedlings exhibited high-temperature-sensitive albinic phenotype. We found that plastid multiple organellar RNA editing factors (MORFs) were targets z. showed...
Starch accounts for over 80% of the total dry weight in cereal endosperm and determines kernel texture nutritional quality. Amyloplasts, terminally differentiated plastids, are responsible starch biosynthesis storage. We screened a series rice mutants with floury to clarify mechanism underlying amyloplast development synthesis. identified endosperm19 (flo19) mutant which shows opaque interior endosperm. Abnormal compound grains (SGs) were present cells mutant. Molecular cloning revealed that...
Meiosis is essential for gametogenesis in sexual reproduction rice (Oryza sativa L.). We identified a MutS-homolog (MSH) family gene OsMSH4 trisomic plant. Cytological analysis showed that developments of both pollen and embryo sacs an Osmsh4 mutant were blocked due to defective chromosome pairing. Compared with the wild type, displayed significant ~21.9% reduction chiasma frequency, which followed Poisson distribution, suggesting class I crossover formation was impaired. Temporal spatial...
Abstract Plants have evolved sophisticated mechanisms to coordinate their growth and stress responses via integrating various phytohormone signaling pathways. However, the precise molecular orchestrating integration of pathways remain largely obscure. In this study, we found that rice (Oryza sativa) short internodes1 (shi1) mutant exhibits typical auxin-deficient root development gravitropic response, brassinosteroid (BR)-deficient plant architecture grain size as well enhanced abscisic acid...
Abstract Floral organ identity is fundamental to species diversity and reproductive success in plants mainly determined by the combinatorial action of MADS homeotic factors. However, despite their conserved roles specifying floral identity, regulation transcription factors remains elusive. Here, we show that rice (Oryza sativa L.) short internode1 (shi1) mutant displays pleiotropic defects development, resulting severe penalties yield grain quality. OsSHI1 mRNA accumulates each whorl,...
As the major storage protein in rice seeds, glutelins are synthesized at endoplasmic reticulum (ER) as proglutelins and transported to vacuoles (PSVs) called PBIIs (Protein body IIs), where they cleaved into mature forms by vacuolar processing enzymes. However, molecular mechanisms underlying glutelin trafficking largely unknown. In this study, we report a mutant, named precursor accumulation6 (gpa6), which abnormally accumulates massive proglutelins. Cytological analyses revealed that gpa6...
Dense vesicles (DVs) are Golgi-derived plant-specific carriers that mediate post-Golgi transport of seed storage proteins in angiosperms. How this process is regulated remains elusive. Here, we report a rice (Oryza sativa) mutant, named glutelin precursor accumulation8 (gpa8) abnormally accumulates 57-kDa proglutelins the mature endosperm. Cytological analyses gpa8 mutant revealed proglutelin-containing DVs were mistargeted to apoplast forming electron-dense aggregates and paramural bodies...
Most of the reported P-type pentatricopeptide repeat (PPR) proteins play roles in organelle RNA stabilization and splicing. However, PPRs involved both splicing editing have rarely been reported, their underlying mechanism remains largely unknown. Here, we report a rice floury endosperm22 (flo22) mutant with delayed amyloplast development endosperm cells. Map-based cloning complementation tests demonstrated that FLO22 encodes mitochondrion-localized PPR protein. Mutation resulting defective...
ABSTRACT Autophagy is a highly conserved cellular program in eukaryotic cells which mediates the degradation of cytoplasmic components through lysosome, also named vacuole plants. However, molecular mechanisms underlying fusion autophagosomes with remain unclear. Here, we report functional characterization rice ( Oryza sativa ) mutant defects storage protein transport endosperm and accumulation numerous root cells. Cytological immunocytochemical experiments showed that this exhibits defect...
Summary Soil salinity has negative impacts on food security and sustainable agriculture. Ion homeostasis, osmotic adjustment reactive oxygen species scavenging are the main approaches utilized by rice to resist salt stress. Breeding cultivars with high tolerance (ST) yield is a significant challenge due lack of elite alleles conferring ST. Here, we report that allele LEA12 OR , which encodes late embryogenesis abundant (LEA) protein from wild Oryza rufipogon Griff., improves increases under...
Abstract A series of nucleotide sugar interconversion enzymes (NSEs) generate the activated donors required for biosynthesis cell wall matrix polysaccharides and glycoproteins. UDP‐glucose 4‐epimerases (UGEs) are NSEs that function in (UDP‐Glc) UDP‐galactose (UDP‐Gal). The roles monocots remain unclear due to redundancy pathways. Here, we report a brittle plant ( bp1 ) rice mutant exhibits leaves culms at all growth stages. had reduced levels rhamnogalacturonan I, homogalacturonan,...
Heading date (or flowering time), an important agronomic trait in crop species, is closely associated with regional adaptation and yield. Members of the Pseudo-Response Regulator (PRR) family play key roles regulating flowering. However, their role molecular mechanism controlling heading rice not very clear. Here, we identified OsPRR protein, OsPRR59, which delayed under long-day conditions. OsPRR59 positively regulates yield by affecting plant height, secondary branches number per panicle,...
Abstract Coat protein complex II (COPII) vesicles play crucial roles in mediating the endoplasmic reticulum (ER) exit of newly synthesized proteins to Golgi eukaryotic cells. However, molecular functions COPII components and their functional diversifications plant seeds remain obscure. Here, we showed that rice (Oryza sativa) glutelin precursor accumulation12 (gpa12) mutant is defective storage export from ER, resulting formation aggregated bodies. Map-based cloning revealed GPA12 encodes a...
Metabolism of strigolactones (SLs) can improve the efficiency nutrient use by regulating development roots and shoots in crops, making them an important research focus for molecular breeding. However, as a very plant hormone, mechanism SL signal transduction still remains largely unknown. In this study, we isolated indica high-tillering dwarf mutant 4 (htd4), spontaneous rice, from restorer line Gui99. Mapping sequencing analysis showed that htd4 was novel allelic D14, which single base...
Plastid-to-nucleus retrograde signaling coordinates nuclear gene expression with chloroplast developmental status and is essential for the photoautotrophic lifestyle of plants. Previous studies have established that tetrapyrrole biosynthesis (TPB) plastid (PGE) play roles in during early biogenesis; however, their functional relationship remains unknown. In this study, we generated a series rice TPB-related gun (genome uncoupled) mutants systematically analyzed effects on under normal...
There is a close regulatory relationship between the circadian clock and abscisic acid (ABA) signaling pathway in regulating many developmental processes stress responses. However, exact feedback regulation mechanism them still poorly understood. Here, we identified rice (Oryza sativa) component PSEUDO-RESPONSE REGULATOR 95 (OsPRR95) as transcriptional regulator that accelerates seed germination seedling growth by inhibiting ABA signaling. We also found OsPRR95 binds to receptor gene...
