These proteins originated in green algae and expanded through multiple duplication events to help plants adapt to terrestrial life. Links to Hormone Networks
HD-Zip proteins are unique to the plant kingdom and are characterized by a linked to a leucine zipper (LZ) motif.
HD-Zip proteins serve as "master switches" that integrate internal hormone signals with external environmental cues. hormon.zip
Regulates responses to abiotic stress (drought, cold) and ABA signaling. Involved in light response and auxin-mediated development. HD-Zip III
Members of the HD-Zip II and III families are strictly linked to auxin machinery, helping adjust plant architecture (like leaf and root development). These proteins originated in green algae and expanded
Some HD-Zip genes are regulated by ethylene and methyl-jasmonic acid, signaling responses to biotic threats like insect herbivores. Functional Classification
Primarily involved in epidermal cell differentiation and lipid metabolism. Regulates responses to abiotic stress (drought, cold) and
HD-Zip proteins, particularly from the HD-Zip I family, regulate ABA homeostasis, which is vital for responding to abiotic stresses like drought and salinity.
