Phenotypic characterization of Arabidopsis thaliana lines overexpressing AVP1 and MIOX4 in response to abiotic stresses.

ABSTRACT:

Premise

AVP1 (H⁺-pyrophosphatase) and MIOX4 (myo-inositol oxygenase) are genes that, when overexpressed individually, enhance the growth and abiotic stress tolerance of Arabidopsis thaliana plants. We propose that pyramiding AVP1 and MIOX4 genes will further improve stress tolerance under water-limited and salt-stress conditions.

Methods

MIOX4 and AVP1 reciprocal crosses were developed and phenomic approaches used to investigate the possible synergy between these genes.

Results

Under normal and stress conditions, the crosses had higher foliar ascorbate content than the wild-type and parental lines. Under water-limited conditions, the crosses also displayed an enhanced growth rate and biomass compared w
