SUMMARYAbscisic acid (ABA) signaling interacts frequently with auxin signaling when it regulates plant development,affecting multiple physiological processes; however, to the best of our knowledge, their interaction duringtomato development has not yet been reported. Here, we found that type 2C protein phosphatase (SlPP2C2)interacts with both flavin monooxygenase FZY, an indole-3-acetic acid (IAA) biosynthetic enzyme, and smallauxin upregulated RNA (SAUR) of an IAA signaling protein and regulates their activity, thereby affecting theexpression of IAA-responsive genes. The expression level of SlPP2C2 was increased by exogenous ABA,IAA, NaCl, or dehydration treatment of fruits, leaves, and seeds, and it decreased in imbibed seeds. Manipu-lating SlPP2C2 with overexpression, RNA interference, and CRISPR/Cas9-mediated genome editing resultedin pleiotropic changes, such as morphological changes in leaves, stem trichomes, floral organs and fruits,accompanied by alterations in IAA and ABA levels. Furthermore, the RNA-seq analysis indicated thatSlPP2C2 regulates the expression of auxin-/IAA-responsive genes in different tissues of tomato. The resultsdemonstrate that SlPP2C2-mediated ABA signaling regulates the development of both vegetative and repro-ductive organs via interaction with FZY/SAUR, which integrates the cross-talk of ABA and auxin signals dur-ing development and affects the expressions of development-related genes in tomato
