Journal ArticleDOI
Reduced DNA methylation in Arabidopsis thaliana results in abnormal plant development
TL;DR: Observations suggest that DNA methylation plays an important role in regulating many developmental pathways in plants and that the developmental abnormalities seen in the methyltransferase antisense plants may be due to dysregulation of gene expression.
Journal ArticleDOI
The molecular basis of vernalization: The central role of FLOWERING LOCUS C (FLC)
TL;DR: It is concluded that FLC is the central regulator of the induction of flowering by vernalization and there is a quantitative relationship between the duration of cold treatment and the extent of down-regulation of FLC activity.
Journal ArticleDOI
Fertilization-independent seed development in Arabidopsis thaliana
TL;DR: This article reported mutants in Arabidopsis thaliana (fertilization independent seed: fis) in which certain processes of seed development are uncoupled from the double fertilization event that occurs after pollination.
Journal ArticleDOI
MINISEED3 (MINI3), a WRKY family gene, and HAIKU2 (IKU2), a leucine-rich repeat (LRR) KINASE gene, are regulators of seed size in Arabidopsis.
TL;DR: The discovery of mutant alleles of two sporophytically acting genes, HAIKU2 and MINISEED3, and the found that both MINI3 and IKU2 showed decreased expression in the iku1-1 mutant, suggest the successive action of the three genes IKu1, IkU2, and MINI 3 in the same pathway of seed development.
Journal ArticleDOI
Expression and parent-of-origin effects for FIS2, MEA, and FIE in the endosperm and embryo of developing Arabidopsis seeds
TL;DR: The promoters of MEA, FIS2, and FIE genes, genes that repress seed development in the absence of pollination, were fused to beta-glucuronidase (GUS) to study their activity pattern, suggesting that these proteins operate in the same system of control of seed development.
