Leaf senescence is the final stage of leaf development. During leaf senescence, nutrients accumulated in mature leaves are broken down and transported to reproductive organs or actively growing young tissues. This process causes reduced photosynthesis, which impacts yield to most
Zhang et al. investigated the molecular features of nine SbPht1 genes that are expressed in response to phosphorus deficiency in sorghum and found that some of these genes are specifically involved in phosphorus uptake and transport in response to low-phosphorus stress.
Grzybowski et al. employed a global, genetically diverse sorghum association panel to explore the variability in metabolic, physiological, and morphological responses to nitrogen deficits and the effect on yield.
When comparing grain to sweet sorghum lines, Osman et al. identified differences in the lectin homologs in the presence/absence of certain other joint domains.They also identified significant overrepresentation of lectins in certain QTLs related to cold and drought tolerance.
