An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Abstract. To elucidate the genetic mechanism that regulates meristem maintenance in monocots, here we have examined the function of the gene FLORAL ORGAN NUMBER2 ( FON2) in Oryza sativa (rice). Seed production in rice (Oryza sativa L.) largely de-pends on the number of flowers, which is in turn regu-lated by the inflorescence architecture. Important Types. However, few studies and little detailed and accurate information of root characteristics were re Li K(1), Yu H(2), Li T(3), Chen G(1), Huang F(4). The OsJAZ1 degron modulates jasmonate signaling sensitivity during rice development. Japonica rice (O. sativa subsp. Mutations in FON2 cause enlargement of the floral meristem, resulting in an increase in the number of floral organs, although the vegetative and inflorescence meristems are largely normal. The importance of rice has been recognised for many centuries - in India it was once known as … RESEARCH ARTICLE. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed. There are two distinct types of domesticated rice, Oryza sativa, or Asian rice and Oryza glaberrima, African rice, both of which have unique domestication histories. Family: Poaceae Barnhart Genus: Oryza L. Oryza sativa L.; Rice is the most widely grown tropical cereal, and over 400 million tonnes of milled rice is produced each year. Characters of Poaceae 2. Oryza sativa is divided into two distinct groups: indica and japonica , which were distinguished as early as in records of the Chinese Han dynasty (approx. The develop-mental process of inflorescence and spikelet in grasses including rice differs considerably from that in other monocotyledonous and dicotyledonous species, and rice, EFFECTS ON INFLORESCENCE INITIATION AND EMERGENCE BY M. F. Department of Agriculture, Ceylon {Received 26 October 1953) (With 3 figures in the text) Although photoperiod eflFects in rice have been extensively studied, the information available is surprisingly meagre. Oryza sativa. The quantitative nature of the response in this plant Economic Importance 4. Affinities 5. Distribution of Poaceae 3. During Hindu festivals such as Deepavali, the Festival of Lights, rice grains are ground into powder, dyed in a variety of colours from blue to pink and used to create intricate designs on the ground called Rangoli. Oryza sativa, commonly known as Asian rice, is the plant species most commonly referred to in English as rice. Oryza sativa rice This plant can be weedy or invasive according to the authoritative sources noted below.This plant may be known by one or more common names in … Oryza sativa is a grass with a genome consisting of 430Mb across 12 chromosomes.It is renowned for being easy to genetically modify, and is a model organism for cereal biology. This root growth defect is caused by a mutation in ABNORMAL INFLORESCENCE MERISTEM1 ( AIM1 ), which encodes a 3-hydroxyacyl-CoA dehydrogenase, an enzyme involved in β-oxidation. {ORYZA SATIVA L.) I. The inflorescence in rice is a terminal ... New Plant Type (NPT) concept. In origin, it is a swamp grass. ... Rice (Oryza sativa) is a type of grain. 100 AD). Rice is a widely cultivated staple in Asia. RESEARCH REPORT. Type-B response regulators of rice play key roles in growth, development and cytokinin signaling ... including roles in inflorescence branching, flower development and fertilization. Here, we report the isolation and characterization of a short root mutant in rice (Oryza sativa) with reduced root meristem activity. ADVERTISEMENTS: In this article we will discuss about:- 1.
