Leaf rolling (LR) is one of the defensive mechanisms that plants have developed against adverse environmental conditions. LR is a typical drought response, promoting drought resistance in various gramineae species, including wheat, maize, and rice. Rice cultivation faces the formidable challenge of water deprivation because of its high water requirements, which leads to drought-related symptoms in rice. LR is an important morphological characteristic that plays a key role in controlling water loss during water insufficiency, thereby regulating leaf area and stature, which are crucial agronomic traits determining yield criteria. Bulliform, sclerenchyma, mesophyll, and vascular bundles are the cells that engage in LR and commonly exhibit adaxial or abaxial types of rolling in rice. The specific genes linked to rolling, either adaxially or abaxially, are discussed here. In addition to the factors influencing LR, here is a short review of the morphological, physiological and molecular responses of this adaptation under drought stress. Moreover, this review highlights how LR combats the consequences of drought stress. The eco-physiological and molecular mechanisms underlying this morphological adaptation in rice should be further explored, as they might be useful in dealing with various degrees of drought tolerance.
