PAP10 — Solanum lycopersicum

Summary

SlPAP10 (SOLYC01G096480.2) on tomato chromosome 1 encodes a thioredoxin-domain protein with protein-disulfide reductase (NAD(P)) activity, disulfide oxidoreductase activity, and enzyme activator activity. It is associated with numerous biological processes including plastid transcription, etioplast organization, hydrogen sulfide metabolism, cytokinin breakdown, and the mevalonate pathway. The gene has been linked to agronomically important traits such as fruit color, carotene and lycopene content, seed weight, fruit size, photosynthetic rate, chlorophyll content, drought tolerance, and salt tolerance. It localizes to the thylakoid, chloroplast nucleoid, and plastid-encoded RNA polymerase complex. Studies of related genes in other species connect the family to chloroplast development and plastid-encoded RNA polymerase-dependent gene transcription.
