Resumen
The cDNA named Cap28 was isolated from an epicotyl cDNA library of Cicer arietinum stressed
seedlings as a clone whose transcript abundance decreased under the PEG-induced water stress.
Since under this condition epicotyl growth was inhibited, the involvement of the corresponding gene
in the growth process was studied. One feature of its encoded protein was the presence of a high
percentage of three amino acids, Glu, Pro and Ala, the first one appearing in pairs. The expression
pattern of the Cap28 corresponding gene suggests that it is associated with developing organs
undergoing cell division and cell elongation and that it may be involved in one of these processes.
Thus, the highest Cap28 expression was found in young epicotyls and decreased in older ones.
Cap28 expression was induced by auxins and brassinolides, suggesting that these hormones could
mediate the processes in which the Cap28-encoded protein is involved. Moreover, Cap28 seems to
be developmentally regulated in view of its higher expression in tissues whose cells undergo division
processes, such as meristematic hooks and apical internodes. High expression was also detected in
early stages of seed development.
