transcription factors. Among them, PIF4 and MYC2 were known to be related to phytohormone metabolism, whereas AP2/ERF113 was involved in meristem activity. PIF4 regulates auxin biosynthesis at high temperature ( Franklin et al., 2011 ) and positively

plant morphology were related to changes in the phytohormone balance. Therefore, the NS158-treated plants produced a wider and more circular spathe could be attributed to the N-related phytohormone balance. The nitrogen requirement and nutrient uptake of
