Abstract

Biobanking (also known as germplasm banking) of genetic material is a well-established concept for preserving plant genetic diversity and also contributes to food security, conservation and restoration. Macroalgae currently represent a very small percentage of the strains in publicly accessible European germplasm banks, despite the increasing recognition of their contribution to achieving several of the United Nations Sustainable Development Goals. There is no strategic coordination of existing macroalgal strains, which could have severe ecological and economic implications as species and their genetic diversity disappear rapidly due to local and global environmental stressors. In this opinion paper, we stress the importance of a coordinated European effort for preserving macroalgal genetic diversity and suggest the development of a three-pillared system to safeguard European macroalgal genetic material consisting of (1) a European Board of Macroalgal Genetic Resources (EBMGR) to provide supervision, support and coordination, (2) a network of germplasm banks consisting of currently existing and newly established infrastructures and (3) an interoperable databank integrating existing databanks. While it will be the task of the EBMGR to identify and coordinate priorities, we offer initial recommendations for preserving macroalgal genetic material, discuss the risks of inaction, and highlight the challenges that must be overcome. Highlights • A coordinated European effort is crucial to preserve macroalgal genetic diversity, addressing rapid species and genetic loss due to environmental stressors. • The initiative should include a European Board of Macroalgal Genetic Resources for oversight, a network of existing and new germplasm banks and an interoperable databank integrating current resources. • The effort supports the United Nations Sustainable Development Goals.

Abstract

Butyric acid and its derivatives are widely applied in aquaculture as an alternative to antibiotics, which are beneficial for the growth and health of aquatic animals. However, these products have some disadvantages including poor stability, a bitter taste, and low bioavailability. In this study, a novel butyric acid, namely pentabutyryl glucose ester (PGE), was synthesized, and the effects of PGE on the growth, liver and intestinal health, and gut microbiota of zebrafish were evaluated. We found that the supplementation of PGE at a level of 0.05% promoted the growth performance of zebrafish, decreased the level of serum LPS, ALT, and AST, and improved liver health. The expression levels of pro-inflammatory factors (NF-κBp65 and IL-6) were notably downregulated, while those of anti-inflammatory factors (TGF-β and IL-10) were upregulated, in the intestines of zebrafish fed 0.05% PGE compared with the control group. Additionally, inclusion of PGE in the diet of zebrafish increased the relative abundance of probiotic bacteria such as Bacillus and Lentilactobacillus. Overall, this study demonstrated that PGE is beneficial for the growth, liver and intestinal health, and the gut microbiota of zebrafish, providing a novel pathway to improve the application of butyric acid as a feed additive in aquaculture.

Abstract

No-till systems grounded in the principles of conservation agriculture can restore the soil organic carbon (SOC) stock and environmental sustainability. Here, we assessed the SOC stocks to 1-m depth for three land-uses (i.e., native vegetation - NV, no-till system – NTS, and plow-based tillage - PBT) across 26 sites in the Cerrado and 37 sites in the Atlantic Forest biomes of Brazil for 3402 soil samples. The depletion of SOC stocks under PBT compared to NV was equivalent to a loss of 38.1 % and 45.8 % of the original NV SOC stock for Cerrado and Atlantic Forest biomes, respectively. The SOC stocks of 16 NTS sites exhibited levels that exceeded those under NV, and SOC stock was restored from 80 to 100 % of its NV levels in 27 other NTS sites across the Brazilian biomes. The SOC stock at seven of 13 edaphoclimatic zones (Clusters) was comparable to or more than that under NV. The duration of NTS to restore SOC stock to that under NV ranged from 36.4 to 55.0 years for the Cerrado and Atlantic Forest biomes, respectively. The NTS/NV SOC stock ratio indicated that one hectare of land under NTS has the potential to avert deforestation for food production of 0.81 ± 0.18 to 1.01 ± 0.15 ha of NV in the Brazilian biomes. In essence, NTS has been demonstrated to effectively restore SOC stocks in Brazil's biomes and play a pivotal role in integrating agriculture as a part of the solution for mitigation strategies for climate change.
