Plants respond to the changing seasons to initiate developmental programmes precisely at
particular times of year. Flowering is the best characterized of these seasonal responses …

Polycomb Repressive Complex 2 (PRC2) is a multiprotein complex that catalyzes the
methylation of lysine 27 on histone H3 (H3K27me). This histone modification is a feature of …

Acclimation to high temperature increases plants' tolerance of subsequent lethal high
temperatures. Although epigenetic regulation of plant gene expression is well studied, how …

Plant cells are totipotent and competent to regenerate from differentiated organs. It has been
known for six decades that cytokinin-rich medium induces shoot regeneration from callus …

Members of the MADS-box transcription factor family play essential roles in almost every
developmental process in plants. Many MADS-box genes have conserved functions across …

Disruption of gene silencing by Polycomb protein complexes leads to homeotic
transformations and altered developmental-phase identity in plants,,,,. Here we define short …

Plant microRNAs (miRNAs) show a high degree of sequence complementarity to, and are
believed to guide the cleavage of, their target messenger RNAs. Here, Ishow that …

Polycomb group (PcG) proteins maintain transcriptional repression during development,
likely by creating repressive chromatin states. The Extra Sex Combs (ESC) and Enhancer of …

Histone methylation plays a fundamental role in regulating diverse developmental
processes and is also involved in silencing repetitive sequences in order to maintain …

Drought, salinity, extreme temperature variations, pathogen and herbivory attacks are
recurring environmental stresses experienced by plants throughout their life. To survive …
