Hypothetical regulatory model for vascular tissue differentiation in Chinese cabbage leaves.

Caption

Hypothetical regulatory model for vascular tissue differentiation in Chinese cabbage leaves. Auxin and ethylene were involved in the differentiation process from procambium to xylem. Xylem is involved in water and mineral element transport. The TFs MYBs and VNDs, as well as IRXs genes regulate and participate in TE formation. Phloem (including SE and CC) is mainly involved in flowering, organic transport, and stress response. TF encoding genes PEAR, HAN, TMO6, and APL are involved in the differentiation process from the procambium to the phloem, whereas many NAC TFs regulate SE formation. EC, epidermis; GC, guard cell; PMC, palisade mesophyll cell; SMC, spongy mesophyll cell; BS, bundle sheath; XP, xylem parenchyma; TE, tracheary elements; PC, procambium cell; PP, phloem parenchyma; SE, sieve elements; CC, companion cells.
