… synthesis of procyanidins of higher molecular weights (15, 16, 19). The decrease in catechin
concentration observed in the present study, however, was not associated with synthesis of …

… Rapid synthesis of proanthocyanidins and catechins, as … increase in 2,4-D concentration
resulted in progressive lowering of the biosynthesis of both catechins and proanthocyanidins…

… of proanthocyanidins reported over the past 12 years in the context of biosynthesis, and …

… SA and BTH enhanced rust resistance by increasing catechin and PA accumulation via
transcriptional activation of PA biosynthesis in poplars. ABA, on the other hand, increased poplar …

… the biosynthesis of the building blocks of proanthocyanidins, the flavan-3-ols (+)-catechin and
… confirmed in the case of proanthocyanidins, where increased levels have been associated …

… procyanidins through the condensation reactions of leucocyanidin with either (+)-catechin or

… Poplar responds to a range of biotic and abiotic stresses by increased biosynthesis and
accumulation of flavan-3-ols in a spatially localized and time-dependent manner. In this study, …

… At least 2–3 times higher levels of catechin and PAs were observed in the leaves of poplar
genotype with moderate resistance against rust infection compared to the ones sensitive to …
