Abstract
Provided are methods and mRNA expression chips for identifying genes that are defined by certain nitrogen and water content relationships in soil. The genes can be up or down regulated under low nitrogen or arid conditions to increase the yield or biomass of crops.
Claims12
An mRNA expression chip containing one or more polynucleotides that are relevant for affecting plant biomass and whose expression is defined by N/W or N×W models.
A method of predicting plant biomass or yield in soil that contains low levels of nitrogen and/or is arid, comprising determining expression of in the plant of one or more genes listed in FIG. 8 and comparing the expression level to a control, wherein up or down regulated expression of the gene compared to control, when referenced to FIG. 8 is indicative of whether the yield or biomass will be higher than normal.
A method for increasing plant biomass or yield comprising altering the expression of a gene, wherein such alteration is shown in FIG. 8 to be correlated positively with an increase in biomass and yield.
