- Abstract:
We report the cloning and DNA sequence of a cDNA from Nicotiana tabacum,
NTGLO, as well as the pattern of expression of the NTGLO gene in wild-type
tobacco plants. The NTGLO cDNA encodes a protein of 209 amino acids, which
shows 73% identity with the GLO protein encoded by the GLO gene of
Antirrhinum majus, a homeotic gene involved in the genetic control of
flower development. Northern blot analysis shows that the NTGLO gene is
expressed mainly in floral organs and, within the flower, expression is
restricted to petals and stamens. The NTGLO gene most probably represents
a true homologue of the GLO gene because: i) the MADS boxes, of the two
genes are highly homologous (56 out of 58 amino acids are identical): ii)
at the carboxy-terminal a block of 19 amino acids is perfectly conserved
between the NTGLO and GLO proteins and iii) their expression patterns in
floral organs are identical.
