The rice genes G1 and TH1 are ALOG family members that are expressed in the lemma, palea, and floral organs and control their identity and development (23, 26). On the other hand, the Arabidopsis ALOG family genes LSH3OBO1 and LSH4 are expressed in shoot organ boundary cells ( 24, 25 ). Rice cultivars BJ1 and Juma, which are traditional cultivar sources for xa13, and IRBB13, which is a xa13containing nearisogenic line derived from the recurrent susceptible parent lines IR24 and BJ1, all failed to show increased levels of Os8N3 expression after inoculation with PXO99 A (Fig. Wheat grain, showing different aspects and cross section to illustrate the depth of the crease The double ridge stage is sometimes considered to be the beginning of floral differentiation, but it occurs when from 40 to 80 percent of the spikelets have been initiated.

Flowering: In a bearing palm, every leaf axil can produce a Spadix or infloresence which under normal conditions various from 12 to 15 annually. The petals of the cotton flower are a creamy white to yellow when the flower first opens. They are narrow at the base and broad at the tip. The petals darken, usually to a dark pink at the end of the first day.

Classification and Botanical Description of Legumes Legumes, or pulses, are flowering plants in the Leguminosae family. The word legume is rice bean (umbellatta), and cowpea (unguiculata) under which label both blackeyed pea and yard long bean fall. Family: Poaceae (Graminae) (The grass family) It is one of the largest families in monocots consisting of 620 genera and about 6000 species. Members are cosmopolitan in distribution.

Rice is a very flexibleadaptable plant that grows well under both flooded and rainfed conditions. The plant comprises vegetative organs: roots, stems, leaves, and reproductive organs; the latter is the panicle made up of spikelets.

Taxonomy To dissect and describe the floral parts of the given parts in the following families. Simultaneously, the number of floral buds (stages 8 to 12) decreased under drought, suggesting that initiation of floral buds was sensitive to water deficit. This supports the idea that stressful environments could limit cell division in the meristem and the transport. Evolution of Plant Homeobox Genes.

From rachis some filaments arise terminated by the glumes that enclose flower until they begins to mature. Flower are protected by two bracts: the inner is called palea and outer is called lemma.

Theme 1 Developmental Biology of Plants leaves, and with the transition to flowering, floral organs. In addition to the genetic information carried by the meristematic cells, internal signal molecules such as growth regulators, and external factors such as light, temperature and availability of nutrients also contribute to the embryonic. The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction, a flower. Study of floral biology and aforesaid mechanisms is essential for determining the mode of pollination of various crop species. Moreover, if selfing has adverse effects on seed setting and general vigour, it indicates that the species is cross pollinated. 1 Whitehead Institute for Biomedical Research, and Department of Biology, Massachusetts Institute of Technology, Cambridge, Massachusetts, USA; 2 Department of Biochemistry and Cell Biology, Rice University, Houston, Texas, USA.
