Transcripts:

• AT5G22090.1     AT5G22090.2

Germplasm Phenotype:

• ear1-1  — Primary root growth inhibited by ABA as compared to wild type, seed germination greening ratio significantly reduced by ABA compared to the wild type. More drought tolerant (higher leaf temperature, less water loss, lower transpiration rate) as compared to wild type. ABA-reduced stomatal aperture was greater as compared to wild type. ABA-inhibited light-induced opening of stomata that had closed in the dark was greater as compared to wild type. PP2C activity was lower and OST1 activity was slightly higher as compared to wild type. Expression of marker genes that are positively regulated by ABA signaling was higher as compared to wild type.
• ear1-1/abi1-2/abi2-2/hab1-1  — Germination inhibited, root growth arrested by ABA, tolerant to drought stress, ABA treatment resulted in lower PP2C and higher OST1 activity.
• ear1-1/snrk2.2/snrk2.3  — Less sensitive to ABA during seed germination as compared to wild type.
• ear1-c  — Primary root growth inhibited by ABA as compared to wild type.
