Electrical conductivity and hypocotyl length of p35S::rHTT2 plants after high-temperature and heat-shock treatments. (a, b) Leaf electrical conductivity of HTT2–2 (a) and HTT2–4 (b) plants. (c) Hypocotyls of HTT2–2 plants. (d) Hypocotyl length of HTT2–2 plants subjected to heat treatment at different temperatures. Error bars represent SD. More than 20 leaves were measured for each plant of each genotype. The hypocotyl lengths of more than 20 HTT2–2 and Bre seedlings were obtained. Differences between genotypes were considered significant (*) if p < 0.05 (Student’s t-test) and highly significant (**) if p < 0.01 (Student’s t-test)
