“…Generally, most submerged leaves do not possess stomata, or, where they do exist but they are nonfunctional (Sculthorpe, 1967). However, floating leaves of aquatic plants, such as the aquatic pteridophyte Marsilea, water lilies, and Potamogeton octandrus have stomata on the upper surface (Lin and Yang, 1999;Rudall and Knowles, 2013;Li et al, 2019). The stomata of terrestrial plants generally distribute more on lower epidermis than upper epidermis in order to reduce water loss.…”

Acclimation to variable CO 2 was studied in floating leaves of the freshwater monocot Ottelia cordata grown in either low or high CO 2. The most striking anatomical variations responding to high CO 2 included the enlarged upper epidermal cells and the decreased area of epidermal chloroplasts. Stomata that distributed on the upper surface, and the stomatic chamber area, showed no significant response to high CO 2. pH-drift experiments indicated that floating leaves of O. cordata were able to use bicarbonate regardless of CO 2 concentrations. Photosynthetic enzyme activities and patterns of organic acids fluctuation confirmed that floating leaves of O. cordata can operate CAM only at low CO 2 , and perform C 4-like metabolism at both high and low CO 2. Overall, the present results imply that the floating leaves of O. cordata does not just rely on the atmospheric CO 2 for its inorganic carbon, but is also dependent on CO 2 and bicarbonate in the water. By showing these effects of CO 2 variation, we highlight the need for further experimental studies on the regulatory mechanisms in O. cordata floating leaves, that prevent futile cycling among the three CO 2 concentrating mechanisms (bicarbonate use, C 4 , and CAM metabolism) and the strategy for exploiting atmospheric CO 2 , as well as studies on the detailed biochemical pathway for C 4 and CAM metabolism in this species.

“…KEGG pathway enrichment analysis demonstrated that many of the DEGs could be classified in the “plant hormone signal transduction” category. Indeed, endogenous levels of hormones such as ABA, cytokinin, GA, and auxin changed between conditions, suggesting that phytohormones play important roles in regulating heterophylly [36,67]. In many heterophyllous plants, stomata and cuticle development are suppressed in submerged leaves.…”

“…One study found that sun leaves (near the top and on the southern sides of trees) of large oaks tend to be more dissected than shade leaves, as leaf dissection could regulate thermal exchanges between leaves and the surrounding environment [76,77]. However, few studies regarding the links between leaf morphology and functions have focused on aquatic plants [36,67]. In addition, the adaptive significance of heterophylly in response to environmental heterogeneity remains unclear.…”

“…Heterophylly is likely an adaptive feature for aquatic and water’s edge environments. The process has evolved multiple times during plant evolution, and it is perceived to be an adaptive mechanism that allows plants to respond to the changeable environment [3,26,27,28,29,36,46,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79]. Thus, heterophylly is a good example of convergent evolution.…”

Leaves show great diversity in shape, size, and color in nature. Interestingly, many plant species have the ability to alter their leaf shape in response to their surrounding environment. This phenomenon is termed heterophylly, and is thought to be an adaptive feature to environmental heterogeneity in many cases. Heterophylly is widespread among land plants, and is especially dominant in aquatic and amphibious plants. Revealing the mechanisms underlying heterophylly would provide valuable insight into the interaction between environmental conditions and plant development. Here, we review the history and recent progress of research on heterophylly in aquatic and amphibious plants.
