Stem transcriptome reveals mechanisms to reduce the energetic cost of shade-avoidance responses in tomato.
While the most conspicuous response to low red/far-red ratios (R:FR) of shade light perceived by phytochrome is the promotion of stem growth, additional, less obvious effects may be discovered by studying changes in the stem transcriptome. Here, we report rapid and reversible stem transcriptome responses to R:FR in tomato (Solanum lycopersicum). As expected, low R:FR promoted the expression of ...
متن کاملInteractions between ethylene and gibberellins in phytochrome-mediated shade avoidance responses in tobacco.
Plants respond to proximate neighbors with a suite of responses that comprise the shade avoidance syndrome. These phytochrome-mediated responses include hyponasty (i.e. a more vertical orientation of leaves) and enhanced stem and petiole elongation. We showed recently that ethylene-insensitive tobacco (Nicotiana tabacum) plants (Tetr) have reduced responses to neighbors, showing an important ro...
متن کاملThe adaptive evolution of plasticity: phytochrome-mediated shade avoidance responses.
Many plants display a characteristic suite of developmental "shade avoidance" responses, such as stem elongation and accelerated reproduction, to the low ratio of red to far-red wavelengths (R:FR) reflected or transmitted from green vegetation. This R:FR cue of crowding and vegetation shade is perceived by the phytochrome family of photoreceptors. Phytochrome-mediated responses provide an ideal...
متن کاملThe Adaptive Evolution of Plasticity: Phytochrome-Mediated Shade Avoidance Responses1
SYNOPSIS. Many plants display a characteristic suite of developmental ‘‘shade avoidance’’ responses, such as stem elongation and accelerated reproduction, to the low ratio of red to far-red wavelengths (R:FR) reflected or transmitted from green vegetation. This R:FR cue of crowding and vegetation shade is perceived by the phytochrome family of photoreceptors. Phytochrome-mediated responses prov...
