Overexpression of MaABI5-like in ‘Fenjiao’ banana improves tolerance to cold stress. a, b Transcript (a) and protein (b) levels of MaABI5-like in ‘Fenjiao’ fruit pulp of empty vector and MaABI5-like-overexpressing fruits was determined by RT–qPCR and western blotting. c ‘Fenjiao’ fruit cold stress storage and ripening process of empty vector and MaABI5-like-overexpressing line. d–h Changes in CI (d), color index (e), firmness of whole fruit (f) and pulp (g), and ethylene production (h) during cold stress storage and fruit ripening. i–k Changes in REC (i), MDA content (j), and proline content (k) during cold stress storage. ^**P < .01, ^***P < .001. l–q Changes in contents of saturated fatty acids (l), unsaturated fatty acids (m), C18:3 (n), C18:2 (o), C18:1 (p), and flavonoids (q) in OE-MaABI5-like and empty control vector ‘Fenjiao’ fruit pulp during storage at 7°C. Different letters indicate significantly different values (P < .05).
