SummaryPhototropism is an adaptive response allowing plants to optimize photosynthetic light capture [1–7]. This is achieved by asymmetric growth between the shaded and lit sides of the stimulated organ [8, 9]. In grass seedlings, the site of photo

Higher plants possess multiple members of the phytochrome family of red, far-red light sensors to modulate plant growth and development according to competition from neighbors. The phytochrome family is composed of the light-labile phyA and several l

Phototropism allows plants to orient their photosynthetic organs towards the light. In Arabidopsis, phototropins 1 and 2 sense directional blue light such that phot1 triggers phototropism in response to low fluence rates, while both phot1 and phot2 m

PIF3 is a repressor of chloroplast development

The phytochrome-interacting factor PIF3 has been proposed to act as a positive regulator of chloroplast development. Here, we show that the pif3 mutant has a phenotype that is similar to the pif1 mutant, lacking the repressor of chloroplast developme

Phytochrome interacting factors 4 and 5 redundantly limit seedling de-etiolation in continuous far-red light

Autor: Christian Fankhauser, Séverine Lorrain, Martine Trevisan, Sylvain Pradervand

Publikováno v: The Plant Journal, vol. 60, no. 3, pp. 449-461
The Plant journal : for cell and molecular biology

Phytochromes are red/far-red photosensors that regulate numerous developmental programs in plants. Among them, phytochrome A (phyA) is essential to enable seedling de-etiolation under continuous far-red (FR) light, a condition that mimics the environ
