Expression

Organism Comment Expression
Malpighia glabra under dark conditions, there is a sharp and significant decline in the total and reduced ascorbate contents, accompanied by a decrease in the level of transcripts and enzyme activities of the two genes in acerola leaves down
Malpighia glabra DHAR transcript and enzyme activity are significantly up-regulated in the leaves of acerola under cold and salt stress conditions up
