Emergence of robust patterns from local rules during plant development.

摘要: The formation of spatial and temporal patterns is an essential component organismal development. Patterns can be observed on every level from subcellular to may emerge local rules that correspond the interactions between molecules, cells, or tissues. emergence robust seem in contradiction with prominent heterogeneity at cellular scales, however it has become increasingly clear instrumental for pattern formation. Here we review recent examples plant development, involving genetic regulation, cell arrangement, growth signal gradient. We discuss how rules, whether stochastic patterned, noise amplified requires filtering achieved. also stress importance modelling investigating such questions.
