TSO1 functions in cell division during Arabidopsis flower development.
We describe an Arabidopsis mutant, tso1, which develops callus-like tissues in place of floral organs. The tso1 floral meristem lacks properly organized three cell layers, and the nuclei of these cells are irregular in size and shape. Further analyses reveal partially formed cell walls and increased DNA ploidy in tso1 floral meristem cells, indicating defects in mitosis and cytokinesis. Our fin...
متن کاملGenome-Wide Analysis of Gene Expression during Early Arabidopsis Flower Development
Detailed information about stage-specific changes in gene expression is crucial for the understanding of the gene regulatory networks underlying development. Here, we describe the global gene expression dynamics during early flower development, a key process in the life cycle of a plant, during which floral patterning and the specification of floral organs is established. We used a novel floral...
متن کاملRegulation of Arabidopsis flower development.
Plant development is governed by intrinsic and environmental factors that regulate the identity and activity of meristems, organized tissues of pluripotent "stem" cells, that together determine plant form and architecture. However, little is known about how these factors act at the molecular leve1 to affect meristem identity and function. Genetic studies in Arabidopsis and other plant species s...
متن کاملGlobal identification of DELLA target genes during Arabidopsis flower development.
Gibberellin (GA) plays important roles in regulating many aspects of plant development. GA derepresses its signaling pathway by promoting the degradation of DELLA proteins, a family of nuclear growth repressors. Although the floral organ identity is established in flowers of the GA-deficient mutant ga1-3, the growth of all floral organs is severely retarded. In particular, abortive anther devel...
متن کاملRegional expression of the rice KN1-type homeobox gene family during embryo, shoot, and flower development.
We report the isolation, sequence, and pattern of gene expression of members of the KNOTTED1 (KN1)-type class 1 homeobox gene family from rice. Phylogenetic analysis and mapping of the rice genome revealed that all of the rice homeobox genes that we have isolated have one or two direct homologs in maize. Of the homeobox genes that we tested, all exhibited expression in a restricted region of th...
