Characterization of PcLEA14, a Group 5 Late Embryogenesis Abundant Protein Gene from Pear (Pyrus communis).

ABSTRACT: Fruit trees need to overcome harsh winter climates to ensure perennially; therefore, they are strongly influenced by environmental stress. In the present study, we focused on the pear homolog PcLEA14 belonging to the unique 5C late embryogenesis abundant (LEA) protein group for which information is limited on fruit trees. PcLEA14 was confirmed to belong to this protein group using phylogenetic tree analysis, and its expression was induced by low-temperature stress. The seasonal fluctuation in its expression was considered to be related to its role in enduring overwinter temperatures, which is particularly important in perennially. Moreover, the function of PcLEA14 in low-temperature stress tolerance was revealed in transgenic Arabidopsis. Subsequently, the pear homolog
