A mutational analysis of leaf morphogenesis in Arabidopsis thaliana.
As a contribution to a better understanding of the developmental processes that are specific to plants, we have begun a genetic analysis of leaf ontogeny in the model system Arabidopsis thaliana by performing a large-scale screening for mutants with abnormal leaves. After screening 46,159 M2 individuals, arising from 5770 M1 parental seeds exposed to EMS, we isolated 1926 M2 putative leaf mutan...
متن کاملHormonal regulation of tomato gibberellin 20-oxidase1 expressed in Arabidopsis.
Gibberellin 20-oxidases, enzymes of gibberellin (GA) biosynthesis, play an important role in (GA) homeostasis. To investigate the regulation of tomato SlGA20ox1 expression, a genomic clone was isolated, its promoter transcriptionally fused to the GUS reporter gene, and the construct used to transform Arabidopsis. Expression was found in diverse vegetative (leaves and roots) and reproductive (fl...
متن کاملRegulation of Meristem Morphogenesis by Cell Wall Synthases in Arabidopsis
The cell walls of the shoot apical meristem (SAM), containing the stem cell niche that gives rise to the above-ground tissues, are crucially involved in regulating differentiation. It is currently unknown how these walls are built and refined or their role, if any, in influencing meristem developmental dynamics. We have combined polysaccharide linkage analysis, immuno-labeling, and transcriptom...
متن کاملLeaf Morphogenesis in Flowering Plants
Leaves, or organs derived from leaves, are the most morphologically diverse structures in a plant (Gifford and Foster, 1989). They occur as prominent photosynthetic structures; as inconspicuous fragments of tissue in tubers, rhizomes, and the stems of many cacti; as nonphotosynthetic storage organs in bulbs; and, in carnivorous plants, as complex structures specialized for catching and digestin...
