Lipid metabolism in green leaves of developing monocotyledons.

abstract：:We have screened a cDNA library prepared from tomato (Lycopersicon esculentum Mill. cv. VFNT Cherry) shoot tips for homeobox-containing clones. The isolated cDNA clone THOM1 (tomato homeobox gene 1) contains a homeobox, a leucine zipper motif and and an acidic region. These features support the hypothesis that the THO...
