Although seemingly desperate, many of the cold acclimation-associated processes ultimately contribute to the increase in cryostability of the plasma membrane, destabilization of which is the primary cause of freezing injury. To understand cold acclimation process comprehensively, we need to characterize the freeze-induced lesions that determine the freezing tolerance and then the mechanism of minimization of these freeze-induced lesions during cold acclimation. In this review, we describe the specific freeze-induced lesions in isolated protoplasts and then several important changes occurring during cold acclimation, which are associated with the minimization of the freeze-induced lesions and, hence, the increase in freezing tolerance. This approach allows us to make strategic plans for molecular breeding of cold-tolerant agricultural plants efficiently. 低温生物工学会 2004-08-30 jpn journal article VoR https://iwate-u.repo.nii.ac.jp/records/9243 1340-7902 低温生物工学会誌 50 1 15 20 https://iwate-u.repo.nii.ac.jp/record/9243/files/cc-v50n1p15-20.pdf application/pdf 443.7 kB 2016-11-14
