A member of the KNOTTED class of homeodomain proteins encoded by the STM gene of Arabidopsis

Article Abstract:

The Arabidopsis shootmeristemless (STM) gene, necessary for the development of shoot apical meristem (SAM) during embryogenesis, encodes a Knotted-like class I protein. A study of the expression of the gene in wild-type plants indicates that the STM gene is necessary for the initiation of the SAM domain. The expression of STM mRNA continues in the seedlings and adult plants, indicating that the gene is also necessary for the maintenance of SAM.

LEAFY blooms in aspen

Article Abstract:

The ectopic expression of LEAFY (LFY) and APETALA1 (AP1) genes in Arabidopsis cause premature flowering in transgenic aspen trees. The LFY and AP1 gene products are present only in floral cells and their expression makes the primordia floral. The LFY and AP1 genes initiate flowering only after a certain a mount of vegetative growth. This may be due to the inability of the primordia of young plants to respond to LFY and AP1 genes.
