PIN1 — Cucumis sativus

Summary

CsPIN1 (CSA_5G472100) on cucumber chromosome 5 encodes a peptidyl-prolyl cis-trans isomerase (EC 5.2.1.8) with cis-trans proline isomerase activity, DNA binding and protein binding functions, and belongs to the PPIase_PpiC_CS and PIN4 domain families. The gene is associated with auxin polar transport, auxin signaling, auxin anabolism, response to gravity, geotropism, regulation of flower development, cell division, cell cycle modulation, rRNA processing, and regulation of protein localization. It localizes to the endoplasmic reticulum, plasmodesmata, mitochondria, cytosol, and nucleus. CsPIN1 has been connected to fruit length, phyllotaxis, adventitious root formation, root gravitropism, iron deficiency tolerance, low temperature tolerance, flowering time, and plant morphogenesis. Studies of related genes in other species link the family to leaf initiation, strigolactone signaling, and insect defense.
