Isopentenyl transferase sequences and Methods of Use thereof in Plants

摘要

Methods and compositions for modulating the level of cytokinins in Plant Development. Polynucleotide sequences and amino acid sequences encoding polypeptides of isopentenyl transferase (IPT) as well as the sequence of amino acids.The sequences can be used in different methods which include Modulation of root Development, Modulation of floral Development, Modulation of Leaf Development and / or outbreaks of Senescence, Modulation, Modulation of the development of the size and / or Weight of Seeds and Modulation of t A type of olerancia plants to abiotic stress.Also provided are polynucleotides comprising an IPT Promoter. The promoter can be used to regulate the expression of a sequence of interest. There are also plants, plant cells and tissues and processed SEED.
