So far we know that light inhibits hypocotyl cell elongation and that the master regulatory plant hormone auxin induces hypocotyl elongation. Light signal depends on cryptochrome (CRY1) and phytochrome (PhyB). Auxin signal follows the traditional TIR1/AFB receptor-mediated degradation of AUX/IAA repressor.…

A Commentary by Jaffé et al. introduces a New Phytologist Virtual Issue on the curious and fascinating plants that hyperaccumulate metals. These diverse species have shed light on metal transporter proteins and mechanisms of metal tolerance, on the ecological function of metal hyperaccumulation (possibly…

Using a traditional breeding approach, introducing a single gene into a desirable cultivar requires repeated backcrossing. This lengthy process can be circumvented through genetic engineering (making transgenic plants), but consumer concerns and extensive, expensive regulatory hurdles have stifled many…

Land plants evolved from freshwater charophyte algae over 450 million years ago and have since diverged into the multitude of plant lineages observed today. The extent to which prominent plant hormones and cognate receptor proteins, which play essential roles in evolutionarily young angiosperms, are…

The cell cycle of plants is regulated by signals that integrate endogenous and environmental cues to allow for adaptation to varying conditions. When a plant is under drought stress, cell division in young leaves is stopped by an active mechanism to conserve resources. Cyclin-dependent kinase-inhibitory…

Phytopathogens secrete effector proteins that enter and manipulate plant cells to facilitate microbial growth in planta. This is often achieved by exerting specific activity onto key host proteins to divert host cellular functions towards supporting pathogen growth. In a recently published article in…

Many fungi are pathogens that kill or weaken their plant hosts. However, there are also many species that form beneficial relationships with plants, algae, and cyanobacteria. One of these mutualisms is the mycorrhizal association between a fungus and a plant root, where the fungus provides the plant…

Are you curious about why and how angiosperms, flowering plants, are the youngest lineage of land plants and have become the most abundant group of plants? You are not alone. Generations of botanists and evolutionary biologists have wondered about this same thing. Many questions have been answered, such…
