摘要： BACKGROUNDSpine grapes are widely cultivated in southern China because of their strong adaptability to hot and humid climates. As a wild species native to China, spine grape (Vitis davidii Fo & euml;x) was studied as a resource of proanthocyanidins (PAs). PA composition, biosynthesis, and histochemistry in different tissues (skins, seeds, and stems) during berry development were analyzed in this study.RESULTSThe findings revealed that PA accumulation occurred in concurrence with flowering and was completed by veraison. High-performance liquid chromatographic results showed that the epicatechin type was the most dominant. The skins were more likely to accumulate PA polymers. Reverse transcription-quantitative polymerase chain reaction analysis revealed that the expression levels of structural genes (flavonoid-3 '-hydroxylase, flavonoid-3 ' 5 '-hydroxylase, dihydroflavonol 4-reductase, leucoanthocyanidin reductase, and leucoanthocyanidin dioxygenase) were positively associated with PA dynamic changes. Histochemical results revealed that PAs in skins were mainly found in the hypodermis of the exocarp, PAs in seeds were mainly found in the middle layer of the outer integument of the testa, and PAs in stems were mainly found in the phloem.CONCLUSIONThis study provides a clear understanding of the spatial and temporal accumulation of PAs in spine grape, and forms a basis for the analysis of structural profiles and synthesis of PAs and their biological effects.
