Cell wall invertase-deficient miniature1 kernels have altered phytohormone levels

Kernels of the Zea mays cell wall invertase (INCW)-deficient miniature1 seed mutant display dramatic decreases in indole-3-acetic acid (IAA) levels and alterations in salicylic acid (SA), jasmonic acid (JA) and abscisic acid (ABA) levels, indicating that alterations in INCW-mediated sucrose cleavage affect downstream hormone homeostasis.
