Plant floral stem cells divide a limited number of times before they stop and terminally differentiate, but the mechanisms that control this timing remain unclear. The precise temporal induction of the Arabidopsis zinc finger repressor KNUCKLES (KNU) is essential for the coordinated growth and differentiation of floral stem cells. We identify an epigenetic(More)
As sessile organisms, plants have evolved multiple mechanisms to respond to environmental changes to improve survival. Arabidopsis plants show accelerated flowering at increased temperatures. Here we show that Jumonji-C domain-containing protein JMJ30 directly binds to the flowering-repressor FLOWERING LOCUS C (FLC) locus and removes the repressive histone(More)
Angiosperms produce flowers for reproduction. Flower development is a multistep developmental process, beginning with the initiation of the floral meristems, followed by floral meristem identity specification and maintenance, organ primordia initiation, floral organ identity specification, floral stem cell termination and finally floral organ maturation.(More)
Flowers are the reproductive units of angiosperms and originate from small number of stem cells maintained at the growing tips of shoots. Flower development is a multistep process starting from an environmental response, followed by the meristem identity change, termination of the stem cell activity, organ polarity control, organ identity determination, and(More)
Epigenetic gene regulation is important for proper development and gene expression in eukaryotes. Maize has a large and complex genome that includes abundant repetitive sequences which are frequently silenced by epigenetic mechanisms, making it an ideal organism to study epigenetic gene regulation. Epigenetic modifications are chromosome-bound, heritable(More)
This paper is a comprehensive review of chroma-tin biology and chemistry as seen in 1968, or eight years after the beginning of this science. Chroma-tin consists of DNA complexed with proteins known as histones. It is shown that histones are comprised of five species which are very much the same in all eukaryotic creatures and conserved in amino acid(More)
