How do legumes know when to start fixing nitrogen? 🌱 Check out this exciting study from the @ssinhar group revealing RSD as the key transcriptional repressor controlling the shift from symbiosome development to nitrogen fixation! #LegumeBiology #Symbiosis
RSD joins the NIN network! Our latest @NewPhyt article from the @ssinhar group from @NIPGRsocial reveals how RSD-mediated suppression of NIN and NLP is the key for symbiotic nitrogen fixation in legumes 🌿

@annusingh1206 @Carbon_Explorer @aditidwivedi_11 3/ 🧪 Wild rice had stronger source strength: ✅ Higher photosynthesis ✅ More primary metabolites in leaves 🌾 Cultivated rice had more efficient sink: ✅ Bigger grains ✅ Higher accumulation of sugars, amino acids, fatty acids

@annusingh1206 @Carbon_Explorer @aditidwivedi_11 1/ To boost rice yield, we need to understand the source (photosynthetic leaves) & sink (developing grains) systems at both genetic & metabolic levels. 2/ We compared 2 cultivated (IR64, Nipponbare) & 2 wild (O. rufipogon, O. australiensis) rice accessions for flag leaf & grain.
