Expression of sHSP genes as affected by heat shock and cold acclimation in relation to chilling tolerance in plum fruit

摘要: Abstract Three full-length cytosol small heat shock protein (sHSP) genes, including two class I sHSP (CI sHSP) and one II (CII cDNAs, termed Ps-CI sHSP1 , sHSP2 Ps-CII respectively, were isolated characterized from plum fruit at harvest. Their expression in relation to cold acclimation-induced chilling tolerance investigated. Heat treatment by dipping the water 55 °C hot for 2 min acclimation conditioning 8 °C 5 d prior storage 2 °C could effectively reduce malondialdehyde (MDA) content alleviate injury. Furthermore, accumulation of mRNA transcripts during subsequent was remarkably enhanced treatments. These data suggest that treatments induced which may be involved caused these
