Claim 1comparative observationsupports2015Source 1DOI

Similar changes in auxin-related genes occur in tomato flower and leaf abscission zones after flower or leaf removal, suggesting similar regulation of abscission in these organs.

Claim 2mechanismsupports2015Source 1DOI

Abscission is a programmed developmental process initiated by auxin depletion.

Claim 3mechanismsupports2015Source 1DOI

Auxin depletion occurs during natural developmental processes, stress-induced abscission, and after artificial organ removal in the tomato model system.

Claim 4mechanismsupports2015Source 1DOI

Auxin depletion results from decreased indole-3-acetic acid biosynthesis and transport and from enhanced IAA transport autoinhibition, conjugation, and oxidative IAA catabolism.

Claim 5mechanismsupports2015Source 1DOI

Stress-induced auxin depletion is mediated by increased ethylene and reactive oxygen species production and carbohydrate starvation.
