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 کاملMULTI-FLORET SPIKELET1, which encodes an AP2/ERF protein, determines spikelet meristem fate and sterile lemma identity in rice.
The spikelet is a unique inflorescence structure of grass. The molecular mechanism that controls the development of the spikelet remains unclear. In this study, we identified a rice (Oryza sativa) spikelet mutant, multi-floret spikelet1 (mfs1), that showed delayed transformation of spikelet meristems to floral meristems, which resulted in an extra hull-like organ and an elongated rachilla. In a...
متن کاملMethyl jasmonate reduces grain yield by mediating stress signals to alter spikelet development in rice.
Jasmonic acid (JA) is involved in plant development and the defense response. Transgenic overexpression of the Arabidopsis (Arabidopsis thaliana) jasmonic acid carboxyl methyltransferase gene (AtJMT) linked to the Ubi1 promoter increased levels of methyl jasmonate (MeJA) by 6-fold in young panicles. Grain yield was greatly reduced in Ubi1:AtJMT plants due to a lower numbers of spikelets and low...
متن کاملHeterochronic development of the floret meristem determines grain number per spikelet in diploid, tetraploid and hexaploid wheats.
BACKGROUND AND AIMS The inflorescence of grass species such as wheat, rice and maize consists of a unique reproductive structure called the spikelet, which is comprised of one, a few, or several florets (individual flowers). When reproductive growth is initiated, the inflorescence meristem differentiates a spikelet meristem as a lateral branch; the spikelet meristem then produces a floret meris...
