Plant genetic sequences associated with vacuolar PH and uses thereof

摘要

Disclosed are genetic and proteinaceous agents capable of modulating or altering the level of acidity or alkalinity in a plant cell, group of cells, organelle, part or reproductive portion of a plant. Further disclosed are methods and agents for modulating or altering pH levels in the vacuole of a plant cell, group of cells, organelle, part or reproductive portion of a plant. Further provided are genetically altered plants, plant parts, progeny, subsequent generations and reproductive material including flowers or flowering parts having cells exhibiting an altered vacuolar pH compared to a non-genetically altered plant. Further provided are methods for modulating or altering flower colour in a plant by the down- regulation of pH in a plant which results in a bluer colour - especially in the flower
