Analysis of the expression of the SlMYB gene during the reproductive development of tomato
(
Solanum lycopersicum
)

Statement of the Problem:
In tomato, the development of the fruit is a highly regulated process at the genetic level that
can be negatively affected by changes in environmental conditions, mainly humidity and temperature. The knowledge of the
molecular mechanisms that control the setting and development of the fruit is very important to identify improvement targets
for this crop. Plant development processes are often controlled by networks of regulatory genes that encode transcription
factors. In a previous work of the laboratory, a transcription factor type MYB (SlMYB) was identified whose expression is
induced in androsterile tomato plants whose ovaries develop in the absence of pollination, giving rise to fruits without seeds
(parthenocarpic). By expression analysis, it was determined that this gene is expressed only in developing flowers.
Methodology & Theoretical Orientation:
The
in situ
hybridization technique is very suitable to obtain information about
the expression patterns of genes in plants, also, express promotor of SlMYB with GUS gene in
Arabidopsis
could reveal the
potential of these genes as a biotechnological tool.
Findings:
Involved primary research with the expression pattern of a gene on the floral structure of
Solanum lycopersicum
and
Arabidopsis thaliana
in the laboratory of Dr Concha Gómez-Mena. Our results show that the messenger of this gene is located
in the sporogenic tissue of the anther, in the developing titles and in the transmission tissue of the pistil. On the other hand,
transgenic
Arabidopsis
pSlMYB::GUS lines have been obtained that show a 2kb sequence of the SlMYB gene promoter capable
of directing the expression of the GUS reporter gene to anther and style tissues.
Conclusion & Significance:
One important conclusion of this research is this gene could regulate male and female meiosis.
