Abstract
The present disclosure teaches the generation of drought tolerant plants. The present disclosure enables manipulation of a phenotypic characteristic referred to as “stay-green” to facilitate drought adaptation in plants by recombinant, mutagenic and/or breeding and selection methods. Plant management practice systems to increase crop yield and harvest efficiency in water-limited environments are also taught herein.
Claims3
A method for increasing water use efficiency in a sorghum plant, said method comprising:
- introducing into a sorghum plant by recombinant DNA technology a recombinant nucleic acid molecule comprising a nucleic acid sequence that encodes a Sorghum bicolor member of the auxin efflux carrier component 2 family (SbPIN2 ) protein
- wherein said nucleic acid sequence encoding the SbPIN2 protein consists essentially of a nucleic acid sequence corresponding to base pair 57449784 to base pair 57453744 of Sorghum Gene ID SBO3g029320 (SbPIN2 ), and
- wherein expression of the nucleic acid molecule confers increased water use efficiency in the sorghum plant compared to a sorghum plant lacking the recombinant nucleic acid molecule.
