DEL1 — Phaseolus vulgaris

Summary

PHAVU_003G196600, designated DEL1 on chromosome 3 of French bean (Phaseolus vulgaris), encodes a protein with DNA-binding and protein-binding activity, containing an E2F winged-helix DNA-binding domain. The gene is associated with downregulation of DNA endoreduplication, upregulation of cell proliferation, secretion, DNA re-duplication, and response to auxin. DEL1 localises to both the cytoplasm and nucleus. Phenotypic associations link this gene to root growth, pathogen resistance, endoreduplication, cell wall biogenesis, lignification, cell proliferation, cell elongation, plant growth, resistance to root-knot nematode, and endocycle. Studies of related genes in other species connect the family to root-knot nematode resistance, cell size, cell expansion, nematode feeding site development, increased DNA content in abaxial epidermal cells, and salicylic acid accumulation, while sequence similarity links extend to leaf shape, cell elongation trait, leaf size, root thickness, disease tolerance, plant growth and development trait, root morphology trait, and other miscellaneous trait.
