Kaempferol rhamnoside catabolism in rosette leaves of senescing Arabidopsis and postharvest stored radish.

Flavonol rhamnosides including kaempferitrin (i.e., kaempferol 3-O-α-rhamnoside-7-O-α-rhamnoside) occur throughout the plant kingdom.

An Apoplastic β-Glucosidase is Essential for the Degradation of Flavonol 3-O-β-Glucoside-7-O-α-Rhamnosides in Arabidopsis.

Flavonol bisglycosides accumulate in plant vegetative tissues in response to abiotic stress, including simultaneous environmental perturbations (i.e. nitrogen deficiency and low temperature, NDLT), but disappear with recovery from NDLT.
