摘要/Abstract

摘要：

中国原产完全甜柿（简称“中国甜柿”或“C-PCNA”）与日本原产完全甜柿（简称“日本甜柿”或“J-PCNA”）具有明显不同的自然脱涩特点。在综述中国甜柿单宁细胞发育特点、单宁成分和单宁含量变化规律的基础上，总结近年来通过转录组学、蛋白组学等手段筛选中国甜柿自然脱涩关键基因及其功能研究的最新进展，以期为中国甜柿自然脱涩机理研究及其遗传改良提供科学依据。

Abstract:

The mechanism of natural deastringency in Chinese pollination constant & non-astringency persimmon（C-PCNA）is distinct from that in the Japanese pollination constant & non-astringency persimmon（J-PCNA）. This review summarizes recent progresses on the developmental characteristics of the tannin cells，tannin components and change patterns in C-PCNA persimmon fruits. Development of the tannin cells in C-PCNA fruits was similar to those of J-PCNA and non-PCNA. Moreover，we highlight recent research progresses for identifying key genes involved in natural deastringency in C-PCNA through mRNA-Seq and iTRAQ-based quantitative proteomic analyses. The significant findings help us to establish a model for elucidating the molecular mechanisms underlying natural deastringency in C-PCNA fruits and promoting breeding of novel C-PCNA cultivars.

Key words: persimmon, Chinese PCNA, natural deastringency, molecular mechanism, genetic improvement
