Understanding the mechanism by which patterned gene activity leads to mechanical
deformation of cells and tissues to create complex forms is a major challenge for …

Brassinosteroids are plant steroid hormones that regulate diverse processes, such as cell
division and cell elongation, through gene regulatory networks that vary in space and time …

Many organisms evolved strategies to survive desiccation. Plant seeds protect dehydrated
embryos from various stressors and can lay dormant for millennia. Hydration is the key …

INTRODUCTION In plants, vascular tissues serve a dual function by providing both structural
support and transport of water, nutrients, hormones, and other signaling molecules …

Higher plant function is contingent upon the complex three‐dimensional (3D) architecture of
plant tissues, yet severe light scattering renders deep, 3D tissue imaging very problematic …

Plants are capable of altering root growth direction to curtail exposure to a saline
environment (termed halotropism). The root cap that surrounds root tip meristematic stem …

Imaging techniques for visualizing and analyzing precise morphology and gene expression
patterns are essential for understanding biological processes during development in all …

Plants transport fixed carbon predominantly as sucrose, which is produced in mesophyll
cells and imported into phloem cells for translocation throughout the plant. It is not known …

Abstract Hydrogen peroxide (H2O2) is an important signaling molecule in plant
developmental processes and stress responses. However, whether H2O2-mediated …
