Abstract In rice (Oryza sativa) and other plants, plant architecture seed size are closely related to yield. Brassinosteroid (BR) signaling the mitogen-activated protein kinase (MAPK) pathway (MAPK 10 [MAPKKK10]–MAPK 4 [MAPKK4]–MAPK6) two major regulatory pathways that control size. However, their possible relationship crosstalk remain elusive. Here, we show WRKY53 mediated between BR MAPK pathway. Biochemical genetic assays demonstrated glycogen synthase kinase-2 (GSK2) phosphorylates...

Abstract Cold tolerance at the booting (CTB) stage is a major factor limiting rice (Oryza sativa L.) productivity and geographical distribution. A few cold-tolerance genes have been identified, but they either need to be overexpressed result in CTB or cause yield penalties, their utility for breeding. Here, we characterize function of cold-induced transcription WRKY53 rice. The wrky53 mutant displays increased CTB, as determined by higher seed setting. Low temperature associated with lower...

Salinity is a major abiotic stress that seriously affects crop growth worldwide. In this work, we aimed to isolate potential halotolerant plant growth-promoting rhizobacteria (PGPR) mitigate the adverse impacts of salt in rice. An isolate, D2, with multiple (PGP) characteristics was identified as Enterobacter asburiae D2. Strain D2 could produce indole-3-acetic acid and siderophore. It also exhibited phosphate solubilization 1-aminocyclopropane-1-carboxylic deaminase activity. Genome...

The 636-bp-long cDNA sequence of OsCu/Zn-SOD (AK059841) was cloned from Oryza sativa var. Longjing11 via reverse transcription polymerase chain reaction (RT-PCR). encoded protein comprised 211 amino acids is highly homologous to Cu/Zn-SOD proteins tuscacera rice and millet. Quantitative RT-PCR revealed that in rice, the level gene expression lowest roots highest petals during S5 leaf stage. Moreover, decreased L5 stage maturity. expression, however, increased under saline–sodic stress NaHCO3...

Grain size and leaf angle are key agronomic traits that determine final yields in rice. However, the underlying molecular mechanisms not well understood. Here we demonstrate Oryza sativa Mitogen Activated Protein Kinase OsMKKK70 regulates grain Overexpressing caused plants to produce longer seeds. The osmkkk62/70 double mutant osmkkk55/62/70 triple displayed significantly smaller seeds a more erect compared wild type, indicating functions redundantly with its homologs OsMKKK62 OsMKKK55....

ABSTRACT Panicle exsertion is one of the crucial agronomic traits in rice ( Oryza sativa ). Shortening panicle often leads to enclosure and severely reduces seed production. Gibberellin (GA) plays important roles regulating exsertion. However, underlying mechanism relative regulatory network remain elusive. Here, we characterized oswrky78 mutant showing severe enclosure, found that defect caused by decreased bioactive GA contents. Biochemical analysis demonstrates OsWRKY78 can directly...

Drought and soil salinization significantly constrain agricultural productivity, driving the need for molecular breeding strategies to enhance stress resistance. Zinc finger proteins play a critical role in plant response abiotic stress. In this study, gene encoding C2H2-type zinc protein (AfZFP5) was cloned from Amorpha fruticosa, species known its strong adaptability. qRT-PCR analysis revealed that AfZFP5 expression is regulated by sorbitol, H2O2, NaCl, NaHCO3. And all four treatments can...
