    Also known as
    ATCTL1; CHITINASE-LIKE PROTEIN 1; CTL1; ECTOPIC DEPOSITION OF LIGNIN IN PITH; ECTOPIC DEPOSITION OF LIGNIN IN PITH 1; ECTOPIC ROOT HAIR 2; ELP; ELP1; ERH2; HOT2; POM-POM1; SENSITIVE TO HOT TEMPERATURES 2; T20M3.12; T20M3_12
    Summary
    Encodes an endo chitinase-like protein AtCTL1. Essential for tolerance to heat, salt and drought stresses. Also involved in root hair development, cell expansion and response to cytokinin. Allelic to erh2. 11 alleles described in Hauser (1995). Mutant is defective in acquired thermotolerance, appears semidwarf throughout its life cycle and has extra lateral branches. There are two EMS alleles. Expression of AtHSP101 is not affected in the mutants.
