*3.6. Interaction Networks Analysis of PebHLHs*

The protein interactions of PebHLHs were predicted using an orthogonal approach to further understand their biological functions. The results showed that 45 PebHLHs had an orthologous relationship with *Arabidopsis*, and 24 interacting proteins had been found. Most of the proteins that interacted with *PebHLHs* were WAKY, JAZ (Jasmonate ZIM-domain), COl (CONSTANS-Like), NINJA (Novel interactor of JA ZIM-domain), EPF (Early Pregnancy Factor), AOS (Allene Oxide Synthase), PFT (Pore-forming Toxin-like), CRY (Crystal protein gene), RBR (Retinoblastoma-related gene), ARF (Auxin response factor) TRY (Tryptophan) and so on (Figure 5). The function of the interacting proteins was related to the stress resistance and development of plants, which indicated that the function of PebHLH was also related to these aspects.
