DNA methylation is a major epigenetic modification of the genome that regulates crucial
aspects of its function. Genomic methylation patterns in somatic differentiated cells are …

Under appropriate in vivo or in vitro conditions, certain somatic plant cells have the
capability to initiate embryogenic development (somatic embryogenesis). Somatic …

DNA methylation can cause heritable phenotypic modifications in the absence of changes in
DNA sequence. Environmental stresses can trigger methylation changes and this may have …

In angiosperms, double fertilization triggers the concomitant development of two closely
juxtaposed tissues, the embryo and the endosperm. Successful seed development and …

Maternal effects can play an important role in a diversity of ecological and evolutionary
processes such as population dynamics, phenotypic plasticity, niche construction, life-history …

that the mutant produced roots that were indistinguishable from wild-type roots when grown
in soil, in a different brand of agar, or in extensively washed Bacto agar, suggesting that the …

Polycomb-group (PcG) genes encode chromatin proteins involved in stable and heritable
transcriptional silencing. PcG proteins participate in distinct multimeric complexes that …

The term apomixis encompasses a suite of processes whereby seeds form asexually in
plants. In contrast to sexual reproduction, seedlings arising from apomixis retain the …

Insect Symbiosis summarizes the current knowledge of the relationship between symbiotic
organisms and their insect hosts and provides an unparalleled analysis of cutting-edge …

Seed development in angiosperms initiates after double fertilization, leading to the formation
of a diploid embryo and a triploid endosperm. The active repression of precocious initiation …
