Webprimordia (Smith and Murashige, 1970; Riv-iere, 1973; Shabde and Murashige, 1977; Baput and Rao, 1977). The possibility of culturing the excised apical meristem of herbaceous angio-sperms enables investigation of some funda-mental questions concerning morphogenetic phenomena associated with the shoot apex. In the case of Coleus blumei … Weboptic primordia appear 13: By the end of the fourth week the optic vesicle lies close to the surface ectoderm. The surface ectoderm overlying the optic vesicle, in response to this contact, has thickened to form the lense placode. 14 (about 32 days) the lens placode is indented by the lens pit. 15 (about 33 days) the lens pit is closed.

WebMar 19, 2024 · Morphogenetic processes are the basis of new organ formation. Lateral roots (LRs) are the building blocks of the root system. After LR initiation and before LR emergence, a new lateral root primordium (LRP) forms. During this period, the organization and functionality of the prospective LR is defined. Thus, proper LRP morphogenesis is a … WebJun 1, 1995 · The expression pattern of the gene in lateral root primordia was confirmed by in situ hybridization with LRP1 cDNA probes. The LRP1 gene encodes a novel protein. LRP1 expression is activated during the early stages of root primordium development and is turned off prior to the emergence of lateral roots from the parent root.
