FERONIA receptor kinase interacts with phosphatidylinositol-anchored proteins LORELEI and LLG1 to ensure its proper functional location in the cell membrane and engages them as co-receptors on the cell surface to mediate a broad spectrum of growth and signaling processes.

Two copies of a Polycomb target gene in the same cell can be maintained in independently heritable expression states, demonstrating that long-term memory of gene expression is stored locally.

The adaptation of Arabidopsis plants to the local environment is linked to DNA methylation.

The expression of small RNAs (or sRNAs) is regulated not only by mRNA expression, but also by their own regulatory elements and by sRNA biogenesis genes.

Both the frequency of sesquiterpene-emitting individuals and the defense capacity of individual plants determine the consequences of sesquiterpene volatile emission for individuals and their neighbors in populations of the wild tobacco Nicotiana attenuata.

Genomic evidence suggests that L-gulonolactone oxidase-the terminal enzyme in vitamin C synthesis, which has been repeatedly lost throughout animal evolution-was lost in plants and other photosynthetic eukaryotes following plastid acquisition.

Environmental heterogeneity may contribute to the high levels of genetic variation in glucosinolate genes found in Arabidopsis thaliana.

The mosses and angiosperms have independently evolved mechanisms that use the same hormones-auxin, cytokinin and strigolactone-to regulate lateral shoot branching.
