in the case of expression of the TPS-3 gene, drought resistant seedlings significantly increase during the first 30 min and again 2 h later to decrease to normal levels from 4 h until 72 h. In susceptible seedlings on the other hand, there was an upregulation in the expression of TPS-3 from 2 to 6 h, and then a downregulation of the expression to the 12 h after start of stress conditions
pathogen infection with Botrytis cinerea and Pseudomonas syringae upregulates isoform TPS5 expression. An isoform TPS5-interacting protein (multiprotein bridging factor 1c) is required for induced expression of isoform TPS5 during pathogen infections. The enzyme expression is upregulated by 0.1 mM methyl jasmonate and 2 mM salicylic acid treatments
the relative expression level of isoform TPS1 gradually increases from 0 h of 4th instar to the highest level at the adult stage. The relative expression level of isoform TPS2 increases obviously from the end of 4th instar and is higher in the whole 5th instar. The expression of isoform TPS3 is relatively higher at the end of the 5th instar and the early stage of adult
with the increase of the salt concentration in the medium, the expression of DvTPS has a slight decrease of 17% in 5 M NaCl compared with 0.5 M condition
