Cold stress has an adverse effect on eggplant growth and is a yield-limiting
factor. Low temperatures are prevalent during early spring cultivation in
temperate climates, and they have a negative impact on eggplant growth and
development. Temperatures below the eggplant`s optimum growth
temperature (22-30ºC) are considered low and detrimental to growth and
development. In this review, we described how eggplants respond to
moderately low and cold temperatures at different scales. We compiled
literature on the current understanding of physiological, cellular responses to
cold stress in eggplant as well as the transcriptional regulation during cold
stress. Subsequently, we also highlight the genetic and molecular evidence,
particularly the function of cold-responsive genes in strengthening cold
tolerance in eggplant. Lastly, we covered the role of mineral nutrients and
useful microorganisms in alleviating the consequences of cold stress in
eggplant roots. Agronomic management practices such as the use of AMF
species may mitigate the detrimental effects of low temperature and the
enhancement of crop varieties with high yield throughout cold stress.
