Photosynthetic organisms must protect themselves from damage during high-light conditions. This Review shows how cyanobacteria trigger such photoprotection using the orange carotenoid protein.
A Review discusses the currently known non-canonical RNA-directed DNA methylation mechanisms, their diversity and interconnections, and puts forward the key unanswered questions in this field.
This Review summarizes current understanding of the non-self- and self-recognition systems of self-incompatibility and their evolution. The non-self-recognition model suggests that the transition from self-compatibility to self-incompatibility could be more common than previously thought.
Dioecious species (those that have distinct male and female plants) are particularly vulnerable to climate change because male and female plants may be spatially segregated and specialized. Female plants will be more impacted by increasing aridity, especially in long-lived species in regions experiencing dramatic climate change. This could lead to an overabundance of male plants at the expense of females in a large number of populations.
