Running head : MFS 1 regulates spikelet development in rice Corresponding
The spikelet is a unique inflorescence structure of grass. The molecular mechanism that controls the development of spikelet remains unclear. In this study, we identified a rice spikelet mutant, multi-floret spikelet1 (mfs1), which showed delayed transformation of spikelet meristems to floral meristems, this resulted in an extra hull-like organ and an elongated rachilla. In addition, the steril...
متن کاملRice plant development: from zygote to spikelet.
Rice is becoming a model plant in monocotyledons and a model cereal crop. For better understanding of the rice plant, it is essential to elucidate the developmental programs of the life cycle. To date, several attempts have been made in rice to categorize the developmental processes of some organs into substages. These studies are based exclusively on the morphological and anatomical viewpoints...
متن کاملA putative lipase gene EXTRA GLUME1 regulates both empty-glume fate and spikelet development in rice
Recent studies have shown that molecular control of inner floral organ identity appears to be largely conserved between monocots and dicots, but little is known regarding the molecular mechanism underlying development of the monocot outer floral organ, a unique floral structure in grasses. In this study, we report the cloning of the rice EXTRA GLUME1 (EG1) gene, a putative lipase gene that spec...
متن کاملTHIS1 is a putative lipase that regulates tillering, plant height, and spikelet fertility in rice.
Proper branching and successful reproductive growth is of great importance for rice productivity. Substantial progress has been made in uncovering the molecular mechanisms underlying tillering control and spikelet sterility. However, rice tillering is developmentally controlled, and how it is regulated coordinately with reproductive growth remains unclear. This study characterized a rice mutant...
متن کاملGibberellic Acid: A Key Phytohormone for Spikelet Fertility in Rice Grain Production
The phytohormone gibberellic acid (GA) has essential signaling functions in multiple processes during plant development. In the "Green Revolution", breeders developed high-yield rice cultivars that exhibited both semi-dwarfism and altered GA responses, thus improving grain production. Most studies of GA have concentrated on germination and cell elongation, but GA also has a pivotal role in flor...
