EXB1 — Cucumis sativus

Summary

CSA_6G522650, also known as EXB1 or WRKY46, encodes a WRKY domain-containing protein that is a DNA-binding transcription factor. This cucumber gene on chromosome 6 is associated with diverse biological processes including abscisic acid-mediated signaling in stomatal movement, gibberellin metabolism, lignin anabolism, and both positive and negative regulation of leaf senescence. It is linked to cellular responses to hydrogen peroxide, sodium and potassium ion homeostasis, and inhibition of salinity response. The gene is associated with numerous traits including plant height, flowering time, leaf morphology, soluble protein and sugar content, auxin and jasmonic acid content, brassinosteroid sensitivity, nitrate sensitivity, and drought tolerance. It is also associated with disease resistance, including responses to bacterial and fungal pathogens, viral defense, and nematode tolerance. The protein localizes to both the cytoplasm and nucleus.
