You can change the display of the base map and layers by clicking on the layer control box in the upper right-hand corner. Rachis - The central supporting structure around which flowers are borne . Oryza sativa L. Family. The primary branch of the ancestral wild rice (Oryza rufipogon Griff.) Inflorescence architecture is diverse in angiosperms, and is mainly determined by the arrangement of the branches and flowers, known as phyllotaxy. TOP TEN tissues for Q67UX7 (Oryza sativa) Organism: Oryza sativa Gene: Q67UX7 Selected probe(set): Os.11634.1.S1_at Platform: Affymetrix Rice Genome Array Expression of Q67UX7 (Os.11634.1.S1_at) across 44 tissues tested by GENEVESTIGATOR: In rice (Oryza sativa), the first morphological change is a rapid increase in meristem size (Hoshikawa, 1989). Poaceae. Indeterminate. In the rice (Oryza sativa) inflorescence or panicle, branch meristems initially produce secondary branch meristems. Oryza sativa L. Rice is the most widely grown tropical cereal, and over 400 million tonnes of milled rice is produced each year. {ORYZA SATIVA L.) I. sativa' complex of rice species, sharing both the AA genome and chromosome number (2n = 24) with the cultivated species, O. sativa and O. glaberrima (Khush, 1997).The African cultigen O. glaberrima was domesticated from the annual wild rice O. barthii in the basin of the upper Niger river in West Africa. 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. Inflorescence branching is a key agronomic trait determining rice yield. Takeoka used the name O. barthii for O. longistaminata, but that name now refers to … Ligule an eciliate membrane; 15–30 mm long; entire, or lacerate; acute. Red rice, weedy rice. Oryza sativa subsp. TOP TEN tissues for Q7XTS4 (Oryza sativa) Organism: Oryza sativa Gene: Q7XTS4 Selected probe(set): Os.50333.1.S1_at Platform: Affymetrix Rice Genome Array Expression of Q7XTS4 (Os.50333.1.S1_at) across 44 tissues tested by GENEVESTIGATOR: Oryza sativa . Varieties differ greatly in the length, shape, and weight … Seed production in rice (Oryza sativa L.) largely depends on the number of flowers, which is in turn regulated by the inflorescence architecture.The developmental process of inflorescence and spikelet in grasses including rice differs considerably from that in other monocotyledonous and dicotyledonous species, and rice, an important crop plant, is often used as a model monocot plant. There are two geographical races of Oryza sativa var. The IM starts to initiate inflorescence branch meristem ( BM ) primordia. These spikelets are variously arranged. The change from distichous vegetative to spiral floral phyllotaxis is often accompanied by a change in the aspect ratio (height:width) of the inflorescence apex. Grains are surrounded by a brown coloured husk. 3. Inflorescence of domesticated rice (Oryza sativa). Inflorescence of sessile disc florets forming the capitulum. HABIT Annual. Flowers&Fruit-----Floral Anatomy-----Fruit Anatomy. The small wind-pollinated flowers are produced in a branched arching to pendulous inflorescence 30–50 cm (12–20 in) long. Oryza includes rice, O. sativa, the staple cereal crop throughout most of S China and tropical Asia. Rice was an obvious choice for the first whole genome sequencing of a cereal crop. The narrow scales at the base of the fertile floret are sometimes regarded as glumes rather than sterile lemmas, the shallow frill at the pedicel apex being then regarded simply as pedicel tissue. Here we demonstrated that SNB and Oryza sativa INDETERMINATE SPIKELET 1 (OsIDS1) together play important roles in inflorescence architecture and the establishment of floral meristems. Leaf-blades 12–65 cm long; 4–18 mm wide. The importance of rice has been recognised for many centuries - in India it was once known as 'dhanya' meaning 'the sustainer of the human race'. 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 cymose inflorescence are of three types – (a) Uniparous or Monochasium Cyme:- In this type the main axis ends in a flower and it produces only one lateral branch at a time ending in a flower and thus the process continues.
