(Submitter supplied) Plants have evolved shoot elongation mechanisms to escape from diverse environmental stresses such as flooding and vegetative shade. The apparent similarity in growth responses suggests possible convergence of the signalling pathways. Shoot elongation is mediated by passive ethylene accumulating in flooded plant organs and by changes in light quality and quantity under vegetation shade. Here we study hypocotyl elongation as a proxy for shoot elongation and delineated Arabidopsis hypocotyl length kinetics in response to ethylene and shade. more...

(Submitter supplied) Unlike the situation in animals, the final morphology of the plant body is highly modulated by the environment. During Arabidopsis development, intrinsic factors provide the framework for basic patterning processes. CLASS III HOMEODOMAIN LEUCINE ZIPPER (HD‐ZIPIII) transcription factors are involved in embryo, shoot and root patterning and during vegetative growth regulate several polarity set‐up processes such as in leaves and the vascular system. more...

(Submitter supplied) Growth of a complex multicellular organism requires coordinated changes in diverse cell types. These cellular changes generate organs of the correct size, shape and functionality. During plant development, the growth hormone auxin induces stem elongation; however, which cell types of the stem perceive the auxin signal and contribute to organ growth is poorly understood. Here, we show that auxin signalling is required in many cell types for correct hypocotyl stem growth, with a key role for the epidermis. more...

(Submitter supplied) To understand which genes acts downstream AtHB1 affecting hypocotyl growth in Arabidopsis thaliana, we performed transcriptional profiles of 4-day-old seedlings grown in a short-day regime comparing wild-type with athb1-1 mutant plants. These results show that some of the AtHB1-regulated genes modulate cell elongation, particularly cell wall composition and elongation, or encode proteins that serve as a source of carbon, nitrogen, and sulfur for early seedling growth.

(Submitter supplied) To identify and characterize genes required for tissue-specific phytochrome responses during hypocotyl development in far-red-light grown bvr lines, we performed gene transcriptional profiling using bvr lines with mesophyll-specific phytochrome inactivation (cab3: :pBVR2). We identified several candidate genes whose expression is significantly altered in lines with mesophyll tissue-specific BVR expression (Cab3::pBVR2), compared to constitutive phytochrome inactivation lines, i.e. more...

(Submitter supplied) The goal of this study is to obtain genome-wide shade-responsive genes in adult plant. We grew plants under long-day condition with high R/FR ratio (simulated "sun" condition) for two weeks. Plants were treated with shade starting at ZT 4 or left in the sun. We prepared two replicates of each sample at 1 hour and 4 hours after sun and shade treatment and five plants were pooled for each replicate. Cotyledons, hypocotyls, and roots were removed from the samples, leaving leaves and apical tissue.
