Genetic control of floral size and proportions.
Floral size is an ecologically important trait related to pollination success and genetic fitness. Independently of the sexual reproduction strategy, in many plants, floral size seems to be controlled by several genetic programs that are to some extent independent of vegetative growth. Flower size seems to be governed by at least two independent mechanisms, one controlling floral architecture t...
متن کاملControl of Organ Size in Plants
The size of plant organs, such as leaves and flowers, is determined by an interaction of genotype and environmental influences. Organ growth occurs through the two successive processes of cell proliferation followed by cell expansion. A number of genes influencing either or both of these processes and thus contributing to the control of final organ size have been identified in the last decade. ...
متن کاملOrgan size control via hydraulically gated oscillations.
Hollow vesicular tissues of various sizes and shapes arise in biological organs such as ears, guts, hearts, brains and even entire organisms. Regulating their size and shape is crucial for their function. Although chemical signaling has been thought to play a role in the regulation of cellular processes that feed into larger scales, it is increasingly recognized that mechanical forces are invol...
متن کاملHAWAIIAN SKIRT controls size and floral organ number by modulating CUC1 and CUC2 expression
The Arabidopsis thaliana F-box gene HAWAIIAN SKIRT (HWS) affects organ growth and the timing of floral organ abscission. The loss-of-function hws-1 mutant exhibits fused sepals and increased organ size. To understand the molecular mechanisms of HWS during plant development, we mutagenized hws-1 seeds with ethylmethylsulphonate (EMS) and screened for mutations suppressing hws-1 associated phenot...
متن کاملMADS Monsters: Controlling Floral Organ Identity
Homeotic genes, which specify the identities of organs or body parts, have been the subject of intensive research in genetics for more than 100 years. William Bateson, in his treatise on genetic variation (Bateson, 1894), coined the term “homeosis” to describe variations in form that resulted in the abnormal patterning or positioning of normal body parts or organs—for example, “modification of ...
