3.3 Expression Profiles of CssHSP Genes in Response to
Stress
The expression pattern of TEA033542 in the tea plant was investigated to
understand its response to heat, salt, drought, and MeJA stress and to
verify the genomic data. For the basic thermotolerance analysis (Figure4A ), the expression level of TEA033542 was observed to be
strongly upregulated after the 40 °C treatment. Protein expression was
relatively high in the leaves at 1 h and then was stable. The TEA033542
expression level was observed to be highest after 24 h MeJA treatment
(Figure 4B ). However, in the genomic data, the expression level
of TEA033542 was observed to be highest at 48 h. The difference may be
due to inconsistent processing conditions. After The expression level of
TEA33542 during both the 200 mM NaCl and the 25% PEG400 treatments was
highest at 36 h (Figure 4C and 4D ). Although the
expression pattern of TEA033542 was different from that of the genome,
analyses indicated that TEA033542 is involved in responses to heat,
salt, drought, and MeJA stress.
