WHY1 — Solanum tuberosum

Summary

PGSC0003DMG400017627 (WHY1, also known as StPTAC11 or StWHY3) on potato chromosome 5 encodes a Whirly family protein with ssDNA-binding and transcription corepressor activity. The gene product is associated with telomere maintenance, plastid transcription, RNA stabilization and transport, chloroplast localization, systemic acquired resistance, antiviral responses, and regulation of gene expression. It localizes to the chloroplast nucleoid and stroma, mitochondria, nucleus, and extracellular regions. WHY1 is associated with thermotolerance, leaf senescence, photosynthetic efficiency, photosystem I activity, flowering time, light adaptation, germination, seed number, and stress tolerance. Related genes in other species are linked to plastid genome stability, telomerase activity, telomere length regulation, disease resistance, and salicylic acid-mediated defense, as well as salt and chilling tolerance.
