I remember when I joined my PhD lab, the first article I was recommanded was a review by Jones and Dangl (2006) titled “The plant immune system”. Even today it remains the first article given to newbies in the lab. But the field has progressed way ahead in the more than fifteen years since that article…

Angiosperm seed formation is an incredibly complex process, considering that it requires coordinating the development of three distinct structures –the embryo, the endosperm and the seed coat– in a small space. However, Doll and Ingram show us that angiosperms faced this challenge by evolving a complex…

Plants must adjust to varying levels of light in order to optimize photosynthetic rates; too little electron transport and plants will incur an energetic penalty, while excessive excitation of photosystem I leads to photodamage. During high light conditions, the increase in DpH acts as a brake on electron…

Cell-to-cell communication is crucial for coordinating plant immunity, development, and environmental adaptations. The main players in sensing signaling molecules are membrane receptor kinases such as Leucine Rich Repeat Receptor Kinases (LRR-RKs). In some cases these receptors detect peptide signals.…

Water loss during photosynthesis is limited by specialized plant cells such as stomata, as well as cuticle formation on the epidermis. In Arabidopsis thaliana, stomata lineage is a good system in which to elucidate the interplay between biochemical signals and mechanical properties during leaf development.…

Leaf features have undergone significant changes during the course of evolution and domestication owing to ecological adaptations and changes in source-sink dynamics. Therefore, wild relatives of crop plants are important resources for exploring the genetic regulation of leaf features that might not…

Plants have a plethora of oxygen requiring enzymes that are essential for survival. Mitochondria require oxygen to create ATP, yet during hypoxia they can alter gene expression in the nucleus through retrograde signaling, which may promote stress tolerance. Barreto et al. recently delineated a novel…

Breeding for flavor in fruits and vegetables is a dauting task. For several years, scientists have relied on consumer panels and instrumental analysis to make judgment calls on the flavor phenotype to select for during a breeding process. While these methods are often accurate and reliable, they are…
