To better monitor and remediate environments contaminated by cadmium (Cd), plants are used as hyperaccumulators or biomonitors; however, few have been identified for aquatic Cd pollution. In our study, two aquatic ornamental plants, Microsorum pteropus (Blume) Copel. and Echinodorus grisebachii Small, were studied for their Cd accumulation capacity, morphological characteristics, and leaf physiological indexes. Microsorum pteropus (Blume) Copel. leaf has the potential to hyperaccumulate Cd (166 mg/kg dry weight for 1 mg/L exposure), with no significant physiological difference under exposure. Echinodorus grisebachii Small had sensitive diagnostic responses to Cd toxicity, such as significant decreases in Chl (a + b) and Chl-a/b, increased peroxidase (POD) activity, greater malondialdehyde (MDA) content, and increased soluble sugar content. These results suggest that Microsorum pteropus (Blume) Copel. could have the potential to be a Cd hyperaccumulator, while Echinodorus grisebachii Small could serve as a biomonitor for Cd-contaminated water bodies.

Grass-type architectural waterscapes (GAWs) utilize submerged plants to enhance self-purification ability and maintain a clear-water state. However, knowledge about their long-term water quality and microbial community dynamics remains limited. This study monitored the water quality, microbial community composition, and networks in two GAWs.

Article Synopsis
- Microsorum pteropus has shown potential as a hyperaccumulator of cadmium (Cd), capable of achieving over 1000 mg/kg in its roots and leaves after exposure to Cd.
- Non-invasive Micro-test Technology (NMT) demonstrated increased hydrogen ion fluxes in all tissues post-Cd exposure, particularly in the stems.
- The plant's response to Cd varies by tissue, with roots absorbing Cd at low levels and demonstrating regulatory mechanisms, while leaves showed direct absorption at low exposure but minimal transport of Cd under high exposure.

The newly defined fern genus Leptochilus contains about 50 species occurring in subtropical to tropical Asia and adjacent Pacific islands. The circumscription and phylogeny of the genus have been ambiguous and its species had been included in various genera such as Colysis, Dendroglossa, Kontumia, Microsorum, and Paraleptochilus. Previous molecular studies sampled only 2-4 molecular markers and 2-16 accessions of Leptochilus.
