Abstract
Described are methods for promoting increase in plant biomass and yield. This increase has its visible effects in organs such as leaf, stem, root and production of fruits and seeds. Further described is the increase in tolerance of those plants to drought, generating plants better adapted to the environmental changes, improving their growth, biomass and yield.
Claims18
A cultivated crop plant having a reduced level of functional wild-type AIP10 protein in comparison to wild-type cultivated crop plant, wherein the reduced level of functional wild-type AIP10 protein is reduced by utilization of:
- a silencing RNA construct directed to AIP10 mRNA in the cultivated crop plant,
- an artificial microRNA directed to AIP10 mRNA in the cultivated crop plant, or
- a genome editing construct directed to an AIP10 gene in the cultivated crop plant.
A recombinant vector comprising:
- a silencing RNA construct directed to AIP10 mRNA,
- an artificial microRNA directed to AIP10 mRNA, or
- a gene editing construct directed to AIP10 gene.
A method for increasing biomass, yield, and/or tolerance to drought in a plant, the method comprising:
- reducing expression of a polynucleotide in the plant that encodes a polypeptide comprising SEQ ID NO:
- 39 and SEQ ID NO:
- 40, or a polynucleotide that encodes a polypeptide having at least 90% sequence identity with SEQ ID NO:
- 39 and SEQ ID NO:
- 40, or
- reducing expression of a functional wild-type AIP10 polypeptide wherein the polypeptide comprises SEQ ID NO:
- 39 and SEQ ID NO:
- 40, or the polypeptide has at least 90% sequence identity with SEQ ID NO:
- 39 and SEQ ID NO:
- 40 so as to increase biomass, yield, and/or tolerance to drought in the plant.
