TCTP — Solanum tuberosum

Summary

PGSC0003DMG400024716 (TCTP) on potato chromosome 1 encodes a translationally controlled tumour protein (TCTP) family member. The product exhibits calcium ion, microtubule, mRNA, siRNA, miRNA and protein binding activities, plus RNA endonuclease and transmembrane receptor protein serine/threonine kinase activities. TCTP is associated with skin development, wound healing, drought recovery, pigmentation, auxin metabolism, root hair tip growth, adventitious root development, asexual reproduction, sporulation, leaf pattern formation, cell cycle modulation, gene silencing by miRNA, and glycan biosynthesis. It localises to the pollen tube, thylakoid, stress granule, apoplast, chloroplast stroma, vacuole, Golgi, plasmodesma, plasma membrane and cytosol. The gene is linked to tuber morphology, leaf vein morphology, viral disease response, aphid response, flowering time, photosynthetic rate, leaf senescence, disease tolerance, root morphology, and brassinosteroid sensitivity. Related genes in other species connect the family to plant regeneration, miRNA activity, and resistance to fungal pathogens.
