Control of plant organ size and shape
WebJan 1, 2008 · Plant organs grow to highly reproducible sizes that are determined by the plant's genotype and by the identity of the organ. The strong heritability of size differences indicates that organ size is under tight genetic control. WebApr 21, 2011 · Progress has been made in elucidating the genetic basis of allometric growth and the role of tissue polarity in shaping organs. We are also beginning to understand how the mechanisms that determine organ identity influence local growth behaviour to generate organs with characteristic sizes and shapes.

WebAlthough plant growth is affected by environmental factors, the final size and shape of organs are species-specific. Understanding the mechanisms controlling organ size and shape in different plant species could shed light on the nature of plant diversity. Meanwhile, organ size and shape directly associate with crop yield and quality. WebJan 1, 2024 · Control of organ size and shape by cell proliferation and cell expansion is a fundamental process during plant development, but the molecular mechanisms that set the final size and shape of determinate organs in plants remain unclear, especially in legumes. In this study, we characterized several mutants including bigger organs (bio) …

WebWe utilised the Arabidopsis petal to study the genetic control of plant organ growth, and identify two closely related U-box E3 ligases PUB25 and PUB26 as important growth regulators by screening the targets of the petal-specific growth-promoting transcription factor RABBIT EARS (RBE). WebApr 21, 2011 · The GRF genes regulate leaf size largely by modulating cell proliferation, as shown by the reduced cell number and organ size in grf5 and grf1 grf2 grf3 triple mutants; by contrast, overexpression of GRF1, GRF2 or GRF5 increases leaf and cotyledon area ( Kim et al., 2003; Kim & Kende, 2004; Horiguchi et al., 2005 ). miR396 accumulates …
WebFigure 1. Main genetic factors controlling lateral organ growth in plants. The final size of a leaf is determined by the rate and duration of cell proliferation and the extent of postmitotic cell expansion. Both growth phases are controlled by a number of growth-promoting and growth-inhibiting factors.
WebSep 20, 2013 · Within one organism, lateral organs of the same type can change in size and shape during ontogeny, a feature called heteroblasty.
