Characterization of germination-specific lipid transfer proteins from Euphorbia lagascae.

abstract：:Abscisic acid (ABA) is an important stress phytohormone that plays an essential role in mediating the signaling networks associated with plant responses to various abiotic stresses. In the present study, we isolated a gene CrNCED1 encoding the rate-limiting enzyme of ABA synthesis, 9-cis-epoxycarotenoid dioxygenase (N...

abstract：:The transport of [14C]glycyl-glycine (Gly-Gly) across the tonoplast of isolated barley vacuoles has been characterized. Uptake of the dipeptide Gly-Gly into barley mesophyll vacuoles was strongly increased by the addition of ATP, while Mg2+ inhibited the ATP-dependent fluxes. Inhibition of the vacuolar proton pump by ...

The course of senescence in leaves of corn seedlings, as measured by the loss of chlorophyll, is shown to be controlled by two correlative influences: a) In the isolated leaf, the base tends to enhance yellowing of the tip region. b) In the leaf attached to the intact plant, correlative aging is delayed by interact...
