The photosynthetic system of maize (Zea mays) leaves is sensitive to low temperatures and suffers from irreversible damage induced by cold exposure, making stress a major factor limiting yield. Identifying genes that improve the recovery photosynthesis in will help enhance tolerance this crop ensure stable yields. Here, we demonstrate role starch phosphorylase 2 (ZmPHOH) promoting damage. Chlorotic leaf3 (chl3), null mutant ZmPHOH, which undergoes chlorophyll degradation chlorosis earlier...
Kernel size is an important factor determining grain yield. Although a number of genes affecting kernel development in maize (Zea mays) have been identified by analyzing mutants, most the corresponding mutants cannot be used breeding programs due to low germination or incomplete seed development. Here, we characterized small kernel7, recessive small-kernel mutant with mutation gene encoding second-largest subunit RNA polymerase III (RNAPΙΙΙ; NRPC2). A frame shift ZmNRPC2 leads premature stop...
Quality protein maize (QPM) (Zea mays L.) varieties contain enhanced levels of tryptophan and lysine, exhibiting improved nutritive value for humans livestock. However, breeding QPM remains challenging due to the complex process rebalancing storage protein. This study conducted transcriptome proteome analyses investigate proteins in opaque2 (o2) QPM. We found a weak correlation between proteome, suggesting significant modulating effect post-transcriptional events on non-zein abundances...
Carbohydrate partitioning is essential for plant growth and development, its hindrance will result in excess accumulation of carbohydrates source tissues. Most the related mutants maize (Zea mays L.) display impaired whole-plant sucrose transport, but other mechanisms affecting carbohydrate have seldom been reported. Here, we characterized chlorotic leaf3 (chl3), a recessive mutation causing leaf chlorosis with starch excessively bundle sheath chloroplasts, suggesting that chl3 defective...
RNA polymerase III (RNAPIII) contains 17 subunits forming 4 functional domains that control the different stages of RNAPIII transcription and are dedicated to synthesis small RNAs such as 5S rRNA tRNAs. Here, we identified 23 genes encoding these in Arabidopsis (Arabidopsis thaliana) further analyzed 5 (NRPC2, NRPC3, NRPC8, NRPABC1, NRPABC2) encoded by 6 with expression patterns belonging sub-complexes. The knockdown repressed tRNAs, causing seed developmental arrest at stages. Among...
