ABSTRACT Grain size is a key determinant of 1,000‐grain weight, one three factors determining grain yield. However, the complete regulatory network controlling has not been fully clarified. Here, we identified rice mutant, named small and round ( srg ) that exhibits semi‐dwarf stature size. Cytological analysis showed cell length number spikelet epidermal cells mutant are reduced, indicating SRG controls by promoting elongation increasing number. encodes kinesin belonging to kinesin‐1...
Carbohydrate partitioning between the source and sink tissues plays an important role in regulating plant growth development. However, molecular mechanisms this process remain poorly understood. In study, we show that elevated auxin levels rice dao mutant cause increased accumulation of sucrose photosynthetic leaves but reduced content reproductive organs (particularly lodicules, anthers, ovaries), leading to closed spikelets, indehiscent parthenocarpic seeds. RNA sequencing analysis...
Abstract In cereal grains, starch is synthesized by the concerted actions of multiple enzymes on surface granules within amyloplast. However, little known about how starch-synthesizing access granules, especially for amylopectin biosynthesis. Here, we show that rice (Oryza sativa) floury endosperm9 (flo9) mutant defective in biosynthesis, leading to grains exhibiting a endosperm with hollow core. Molecular cloning revealed FLO9 encodes plant-specific protein homologous Arabidopsis...
CYP78A, a cytochrome P450 subfamily that includes rice (Oryza sativa L.) BIG GRAIN2 (BG2, CYP78A13) and Arabidopsis thaliana KLUH (KLU, CYP78A5), generate an unknown mobile growth signal (referred to as CYP78A-derived signal) increases grain (seed) size. However, the mechanism by which CYP78A pathway size remains elusive. Here, we characterized small mutant, grain4 (smg4), with smaller grains than its wild type due restricted cell expansion proliferation in spikelet hulls. SMG4 encodes...
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,...
Plants are subject to attack by diverse pests and pathogens. Few genes conferring broad-spectrum resistance both insects pathogens have been identified. Because of the growth-defense tradeoff, it is often challenging balance biotic stress yield for crops. Here, we report that OsWRKY36 suppresses via transcriptional repression Phenylalanine Ammonia Lyases (PALs), a key enzyme in phenylpropanoid pathway rice. Knocking out causes elevated lignin biosynthesis increased sclerenchyma thickness...
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...
Mongolian willow (Salix linearistipularis) is a naturally occurring woody dioecious plant in the saline soils of north-eastern China, which has high tolerance to alkaline salts. Although transcriptomics studies have identified large number salinity-responsive genes, mechanism salt not clear. Here, we found that response Na2CO3 stress, regulates osmotic homeostasis by accumulating proline and soluble sugars scavenges reactive oxygen species (ROS) antioxidant enzymes non-enzymatic...
