Lee et al. (2009) identified a new gene, DEG13, which
is associated with the microspore embryogenesis in
pepper and is highly expressed under high-temperature
stress. The sequence of nucleotides showed that DEG13 is
homologous with the POACT88 gene from potato (≈91%),
as well as with the alcohol dehydrogenase gene from
Arabidopsis (≈70%), both activated by stress. Two gene
sequences, PELTP and PEGST, which were expressed in
the early stages of microspore embryogenesis in pepper,
were identified. PELTP is highly homologous with the LTP
of pepper and PEGST with the GST gene of pepper (98%
and 99%, respectively). The authors presume that the two
genes may play an important role in the early stages of
pepper microspore embryogenesis (Zhang et al., 2008).
