Editorial: Amaranthus: naturally stress-resistant resources for improved agriculture and human health, volume II

Abstract

In this edition of the Research Topic, we discuss advantages of the genus Amaranthus, which is a group of dicotyledonous plants with adaptation traits to abiotic and climate stresses. Some are used as sources of grain, flours, leafy vegetables, fodders and industrial products. As a C4 photosynthetic group, Amaranthus have more efficient carbon fixation than C3 photosynthetic plants especially at high temperatures and under drought (Das, 2016). As carbon dioxide in the atmosphere has increased some of this advantage may diminish but their drought, salt and heat tolerance strategies are valuable (see articles discussed in previous Research Topic issues editorial of Riggins et al. (2021).
