The QTL GNP1 Encodes GA20ox1, Which Increases Grain Number and Yield by Increasing Cytokinin Activity in Rice Panicle Meristems
Cytokinins and gibberellins (GAs) play antagonistic roles in regulating reproductive meristem activity. Cytokinins have positive effects on meristem activity and maintenance. During inflorescence meristem development, cytokinin biosynthesis is activated via a KNOX-mediated pathway. Increased cytokinin activity leads to higher grain number, whereas GAs negatively affect meristem activity. The GA...
متن کاملEnhanced Sucrose Loading Improves Rice Yield by Increasing Grain Size.
Yield in cereals is a function of grain number and size. Sucrose (Suc), the main carbohydrate product of photosynthesis in higher plants, is transported long distances from source leaves to sink organs such as seeds and roots. Here, we report that transgenic rice plants (Oryza sativa) expressing the Arabidopsis (Arabidopsis thaliana) phloem-specific Suc transporter (AtSUC2), which loads Suc int...
متن کاملActivation of Big Grain1 significantly improves grain size by regulating auxin transport in rice.
Grain size is one of the key factors determining grain yield. However, it remains largely unknown how grain size is regulated by developmental signals. Here, we report the identification and characterization of a dominant mutant big grain1 (Bg1-D) that shows an extra-large grain phenotype from our rice T-DNA insertion population. Overexpression of BG1 leads to significantly increased grain size...
متن کاملEffect of seed priming and application of cytokinin and auxin on growth and grain yield of wheat (Triticum aestivum L.) under Ahvaz climatic conditions
In order to evaluate the effect of seed priming and application of cytokinin and auxin on grain yield of wheat cv. Chamran, an experiment was carried out in Agriculture Faculty of Shahid Chamran University of Ahvaz, Iran, during 2015-2016 and 2016-2017 growing seasons. Experiment was carried out in a factorial arrangement based on randomized complete block design with three replications. Treatm...
