Abstract
Methods for increasing or decreasing Nitrogen (N) uptake/assimilation and/or usage in plants comprising over-expressing or repressing one or more transcription factors that have been identified by evaluating temoporal transcription of the TFs in response to N signaling and validated based on TF perturbation studies in plant cells and plants. Combinations of TFs may be used, where each TF may be independently induced or repressed to achieve a desired increase or decrease in N uptake/assimilation.
Claims8
A method for modulating Nitrogen (N) uptake, assimilation and/or usage in plant cell or a plant comprising under-expressing transcription factor CRF4, wherein the under expressing comprises editing a segment of a CRF4 gene, or comprises RNA interference (RNAi)-mediated targeting of mRNA encoding CRF4, the method further comprising overexpressing transcription factor SNZ and/or CDF1 such that the plant or plant cell has increased N assimilation.
