Abstract
Leading crops such as cotton, maize, rice and wheat were the first to be studied using omics technologies (genomics, transcriptomics, proteomics and metabolomics). Those crops that are considered less significant, such as okra (Abelmoschus esculentus (L.) Moench), are yet to follow. Okra, grown in tropical and subtropical regions, is an economically important vegetable crop with high nutritional qualities and health-related benefits. In this review, the justification for okra to benefit from omics technologies is highlighted and the discussion is limited to the influence of heat stress, aluminium toxicity and exposure to Bacillus subtilis as environmental factors, which can be studied to enhance our understanding of okra growth and adaptation. The implications of okra benefiting from the potential of omics technologies are also briefly discussed.
