Light is an essential environmental factor for photosynthetic organisms, serving as a source of energy and signal information. To precisely perceive and respond to different wavelengths of the light spectrum, eukaryotic photosynthetic microorganisms and higher plants have developed different classes…

Water deficit (WD) is one of the main environmental stress factors affecting crops and global food security. Acclimation to WD, however, enables plants to maintain growth under unfavorable environmental conditions. To shed light on the molecular mechanisms underlying WD acclimation, Rymaszewski et al.…

Auxin regulates many aspects of growth and development in land plants, but the origin and evolution of auxin signaling and response mechanisms remain largely unknown. Genome analyses of the moss Physcomitrella patens revealed the presence of the principal gene families involved in auxin homeostasis and…

Root hairs are long tubular extensions of root epidermal cells that greatly increase the root surface area and thereby assist in water and nutrient absorption. Root hairs are found in nearly all vascular plants, including angiosperms, gymnosperms, and lycophytes, and they exhibit similar cellular features,…

The waxy cuticle, a key barrier to desiccation and pathogen entry, is a dynamic structure, the composition, area, permeability and thickness of which can change in response to environmental conditions.  For example, water deficit in Arabidopsis (Arabidopsis thaliana) triggers an increase in the accumulation…

Methionine is a nutritionally essential sulfur-containing amino acid found at low levels in plants and in their seeds. It often limits the nutritional value of crop plants as a source of dietary protein for humans and animals.  In plants, methionine plays key roles in protein synthesis and mRNA translation,…
