Fig. 2From: Proanthocyanidin accumulation and transcriptional responses in the seed coat of cranberry beans (Phaseolus vulgaris L.) with different susceptibility to postharvest darkeningEffect of postharvest storage on seed coat quality of darkening and non-darkening cranberry bean RILs. For both RILs, mature cranberry beans were maintained under (a) greenhouse conditions for 22 d or (b) in a sealed plastic bag at 4 °C for 48 months (c) DMACA staining of aged seeds from both RILs as described under Methods.
