Root gravitropism relies on gravity perception by the root cap and requires tightly regulated phytohormone signaling. Here, we isolate a rice mutant that displays coiling in hydroponics but normal gravitropic growth soil. We identify COILING ROOT IN WATER 1 (CRW1) encoding an ETHYLENE-INSENSITIVE3 (EIN3)-BINDING F-BOX PROTEIN (OsEBF1) as causative gene for phenotype. show OsCRW1-EIN3 LIKE 2 (OsEIL1/2)-ETHYLENE RESPONSE FACTOR 82 (OsERF82) module controls production of reactive oxygen species tip, subsequently impacting stability, polar localization PIN-FORMED (OsPIN2), symmetric distribution auxin, ultimately roots. The OsEIL1/2-OsERF82 ethylene signaling is effectively impeded applying gentle mechanical resistance to tips, including growing water-saturated paddy further mechanosensing-induced calcium required sufficient antagonizing pathway. This study has revealed previously unanticipated interplay among ethylene, mechanosensing control plant gravitropism.

Background Amino acids are not only the main form of N in rice, but also vital for its growth and development. These processes facilitated by amino acid transporters within plant. Despite their significance, a few AAP have been reported. Results In this study, we observed that there were differences expression transporter OsAAP7 among 521 wild cultivated rice varieties, it directly negatively correlated with tillering grain yield per We revealed protein was localized to endoplasmic reticulum had absorption transport affinity such as phenylalanine (Phe), lysine (Lys), leucine (Leu), arginine (Arg) using subcellular localization, yeast substrate testing, fluorescent uptake, content determination. Further hydroponic studies showed exogenous application Phe, Lys Arg inhibited axillary buds overexpression lines, promoted elongation mutant lines. Finally, RNA-seq analysis patterns genes related nitrogen, auxin cytokinin pathways changed transgenic plants. Conclusions This study gene function , found blocking CRISPR/Cas9 technology determining basic neutral accumulation rice.

Ethylene regulates plant growth, development, and stress adaptation. However, the early signaling events following ethylene perception, particularly in regulation of receptor/CTRs (CONSTITUTIVE TRIPLE RESPONSE) complex, remains less understood. Here, utilizing rapid phospho-shift rice OsCTR2 response to as a sensitive readout for signal activation, we revealed that MHZ3, previously identified stabilizer ETHYLENE INSENSITIVE 2 (OsEIN2), is crucial maintaining phosphorylation. Genetically, both functional MHZ3 receptors prove essential physically interacts with subfamily I II receptors, e.g., OsERS2 OsETR2 respectively, stabilizing their association thereby activity. treatment disrupts interactions within protein complex MHZ3/receptors/OsCTR2, reducing phosphorylation initiating downstream signaling. Our study unveils dual role fine-tuning providing insights into initial stages cascade.

High night-time temperatures (HNT) pose a threat to the sustainability of crop production, including rice. HNT can affect productivity and quality by influencing plant physiology, morphology, phenology. The ethylene perception inhibitor, 1-methylcyclopropene (1-MCP), minimize HNT-induced damage membranes, thereby preventing decrease in rice yield. In this study, we employed transcriptome approach investigate effects HNT, 1-MCP, their interaction on two Texas varieties, Antonio Colorado. plants were exposed 25°C (ambient temperature, ANT) 30°C using an infrared heating system from booting stage until harvest, while 1-MCP was applied at development. Several physiological agronomical traits evaluated under each condition assess responses. Leaf tissues collected grown ANT conditions after heat stress treatments. Based agronomic performance, Colorado less negatively affected than showing slight reduction spikelet fertility leaf photosynthetic rate but no significant application significantly mitigated adverse Antonio. However, differences observed yield Furthermore, transcriptomic data revealed distinct responsive mechanisms response both 1-MCP. senescence-related transcription factors (TFs) identified only Antonio, suggesting that signaling pathway not These findings contribute our understanding between varieties exhibiting susceptible tolerant responses high temperatures, as well regulation
