A LEAFY link from outer space
Article Abstract:
Parcy and colleagues have shown that the LEAFY (LFY) protein has direct involvement in the activation of transcription of homeotic genes, along with UNUSUAL FLORAL ORGANS (UFO), a co-regulator. Their study used Arabidopsis thaliana, whose flowers are formed on the flanks of inflorescence meristems. They made a constitutively active LFY variant with fusion of a transcriptional-activator domain to the LFY gene. The transgenic plants expressed AG genes outside the flowers and early expression of A-gene function APETALA1 was raised.

Analysis of 1.9 Mb of contiguous sequence from chromosome 4 of Arabidopsis thaliana
Article Abstract:
It has been possible to use the yeast artificial chromosome-based physical map of chromosome 4 to construct a sequence-ready map of cosmid and bacterial artificial chromosome clones covering a 1.9-megabase (Mb) contiguous region of the plant Arabidopsis thaliana. A region between markers COP9 and G3845 on the long arm of chromosome 4 from the ecotype Columbia was chosen for sequencing. It was found that there is a consistently high gene density over an extended contiguous region, with 389 predicted genes in 1.87 Mb.
