Rice belongs to monocotyledon which is characterized by having a so-called fibrous root system. Such root system is built up with seminal and nodal roots with numerous lateral roots. Morphology and anatomy of rice roots which is fundamentally the same as other cereal crops, has been relatively by: Domenico De Martinis, in Developments in Plant Genetics and Breeding, Plant development. Ethylene does act to slow growth of many plant tissues. This can be easily seen in transgenic tobacco in which auxin overproduction and its concomitant ethylene overproduction causes a strong apical dominance and a large reduction in internode elongation. Stages of development of a monocot embryo, such as in rice. (a) The fertilized egg cell (zygote) undergoes (b) mitosis to form an axial (A) and a basal (B) cell.   Self-maintenance of the shoot apical meristem (SAM), from which aerial organs are formed throughout the life cycle, is crucial in plant development. Class I Knotted1-like homeobox (KNOX) genes restrict cell differentiation and play an indispensable role in maintaining the SAM. However, the mechanism that positively regulates their expression is Cited by:

  The tip of the root is covered by a thimble-shaped root cap that is the site of perception and transduction for many environmental stimuli. Until now, little was known about how the root cap of rice (Oryza sativa) develops and functions to regulate the adaptive behavior of the root. To address this, we examined the formation of the rice root cap during Cited by:   Abstract. Rice evolved a diversified determinate inflorescence (also called panicle), and rice panicle development includes high orderly and complex biological events including the formation of lateral branches and spikelet organs. Morphology, Plant (also phytomorphology), the study of the structure and form development of plants in their individual and evolutionary-historical development. It is one of the most important branches of botany. As plant morphology developed, the following independent sciences were established: plant anatomy, which studies the tissue and cell structure. Formation, Maintenance and Function of the Shoot Apical Meristem in Rice Article Literature Review in Plant Molecular Biology 60(6) May with .

  Poaceae, one of the largest flowering plant families in angiosperms, evolved distinct inflorescence and flower morphology diverging from eudicots and other monocots. However, the mechanism underlying the specification of flower morphology in grasses remains unclear. Here we show that floral zygomorphy along the lemma-palea axis in rice (Oryza . Plant development is the result of meristem production (organogenesis) that creates new organs such as leaves, internodes, fruits, rings inside branches, or roots. Although the structures of inflorescence show regular patterns (Figure 1), which have been described already long ago, the development of shrubs and trees looks more complicated and was not carefully studied before . Plant morphology "represents a study of the development, form, and structure of plants, and, by implication, an attempt to interpret these on the basis of similarity of plan and origin". There are four major areas of investigation in plant morphology, and each overlaps with another field of the biological sciences.. First of all, morphology is comparative, meaning that the morphologist.   During vegetative development in all grasses, including rice, each apical meristem produces a module that consists of a series of metamers (Room et al., ). Each metamer is comprised of an internode with, at the distal end, an axillary meristem and a leaf sheath connected to a leaf by:
