There is large diversity among glutathione peroxidase (GPx) enzymes regarding their function, structure, presence of the highly reactive selenocysteine (SeCys) residue, substrate usage, and reducing agent preference. Moreover, most vertebrate GPxs are very distinct from non-animal GPxs, it still unclear if they came a common GPx ancestor. In this study, we aimed to unveil how evolved throughout different phyla. Based on our phylogenetic trees sequence analyses, propose that all encoding...
Iron (Fe) and zinc (Zn) are essential micronutrients required for proper development in both humans plants. Rice (Oryza sativa L.) grains the staple food nearly half of world's population, but a poor source metals such as Fe Zn. Populations that rely on milled cereals especially prone to Zn deficiencies, most prevalent nutritional deficiencies humans. Biofortification is cost-effective solution improvement quality crops. However, better understanding mechanisms underlying grain accumulation...
Anther development is a complex process essential for plant reproduction and crop yields. In recent years, significant progress has been made in the identification characterization of bHLH transcription factor family involved anther regulation rice Arabidopsis, two extensively studied model plants. Research on factors unveiled their crucial function controlling tapetum development, pollen wall formation, other anther-specific processes. By exploring deeper into regulatory mechanisms...
Background Triacylglycerols (TAGs) are the main seed storage lipids of plants. TAGs chemichal properties largely dependent on their fatty acid composition. Diacylglycerol Acyltransferase (DGAT) genes encode enzymes needed for TAG biosynthesis. Different types DGAT (named DGAT1, DGAT2, DGAT3 and DAcT) have been identified in DGAT1 DGAT2 well characterized, but little is known about DAcT most plant species. The understanding biosynthesis enzymatic steps its transcriptional regulation plants...
The diversity of diacylglycerol acyltransferases (DGATs) indicates alternative roles for these enzymes in plant metabolism besides triacylglycerol (TAG) biosynthesis. In this work, we functionally characterized castor bean (Ricinus communis L.) DGATs assessing their subcellular localization, expression seeds, capacity to restore biosynthesis mutant yeast and evaluating whether they provide tolerance over free fatty acids (FFA) sensitive yeast. RcDGAT3 displayed a distinct located vesicles...
