“…As one of the most carbon-rich ecosystems worldwide ( Senger et al., 2021 ), mangroves are mostly found in tropical and subtropical coastal regions. Carbon sequestration by mangroves also plays a vital role in mitigating global warming and reducing greenhouse gas emissions ( Gu et al., 2022 ). However, mangrove forests worldwide are declining at a rate of 1-2% per year due to continuous human disturbance ( Goldberg et al., 2020 ).…”

As an important mangrove species, Kandelia obovata plays an irreplaceable role in the coastal ecosystem. However, due to a lack of genetic technology, there is limited research on its functional genes. As such, establishing an efficient and rapid functional verification system is particularly important. In this study,tobacco rattle virus (TRV) and the phytoene desaturase gene KoPDS were used as the vector and target gene, respectively, to establish a virus-induced gene silencing system (VIGS) in K. obovata. Besides, the system was also used to verify the role of a Chlorophyll a/b binding protein (Cab) gene KoCAB in leaf carbon sequestration of K. obovata.RNA-Seq and qRT-PCR showed that the highest gene-silencing efficiency could reach 90% after 10 days of inoculation and maintain above 80% after 15 days, which was achieved with resuspension buffer at pH 5.8 and Agrobacterium culture at OD600 of 0.4-0.6. Taken together, the TRV-mediated VIGS system established herein is the first genetic analysis tool for mangroves, which may greatly impel functional genomics studies in mangrove plants.

“…Similar to south Florida analyses, we combined data for NPP from co-located sites of determination using sap flow techniques. NPP of the mangrove forests were measured using multiple procedures (including eddy flux) for improved accuracy 68 , 69 . The relationships of predicted NPP versus and observed NPP versus did not differ between Florida and China (t = 0.48, p = 0.643).…”

Abstract“Blue carbon” wetland vegetation has a limited freshwater requirement. One type, mangroves, utilizes less freshwater during transpiration than adjacent terrestrial ecoregions, equating to only 43% (average) to 57% (potential) of evapotranspiration ($$ET$$ ET ). Here, we demonstrate that comparative consumptive water use by mangrove vegetation is as much as 2905 kL H2O ha−1 year−1 less than adjacent ecoregions with $${E}_{c}$$ E c -to-$$ET$$ ET ratios of 47–70%. Lower porewater salinity would, however, increase mangrove $${E}_{c}$$ E c -to-$$ET$$ ET ratios by affecting leaf-, tree-, and stand-level eco-physiological controls on transpiration. Restricted water use is also additive to other ecosystem services provided by mangroves, such as high carbon sequestration, coastal protection and support of biodiversity within estuarine and marine environments. Low freshwater demand enables mangroves to sustain ecological values of connected estuarine ecosystems with future reductions in freshwater while not competing with the freshwater needs of humans. Conservative water use may also be a characteristic of other emergent blue carbon wetlands.

“…Net primary production (NPP) is the basis of all ecosystem services (Alcamo et al, 2003) and a comprehensive ecological indicator (Haberl, 1997;McNaughton et al, 1989;Zhou et al, 2015). In forests NPP can be assessed indirectly by field measurements (Clark et al, 2001) and modelled (Ruimy et al, 1999;Running et al, 2000;Cramer et al, 1999) but needs further improvement (Gu et al, 2022;Chaubey et al, 2022). Chambers et al (2001) showed that the loss of tree mass over time can lead to underestimates in above-ground net primary productivity of forests if not quantified properly.…”
