“…Such large differences in productivity, particularly when water is limited, are game changers, especially when considering cultivating biomass crops on marginal land to achieve carbon sequestration, phyto-remediation, soil stabilization, and providing new business opportunities for rural economies. A recent EU project entited 'Miscomar' (Miscanthus for contaminated and marginal land) showed that novel Miscanthus hybrids, with similar water conservation traits to GNT-10, when grown on metal contaminated land excluded heavy metals over a period of three years [31] suggesting Miscanthus could be used to bring contaminated land back in to useful production. The approach taken thus far in domesticating Miscanthus reflects the early days of domesticating a crop that had attracted relatively little research funding.…”

Miscanthus, a C4 perennial grass native to Eastern Asia, is being bred to provide biomass for bioenergy and biorenewable products. Commercial expansion with the clonal hybrid M. × giganteus is limited by low multiplication rates, high establishment costs and drought sensitivity. These limitations can be overcome by breeding more resilient Miscanthus hybrids propagated by seed. Naturally occurring fast growing indigenous Miscanthus species are found in diverse environments across Eastern Asia. The natural diversity provides for plant breeders, the genetic resources to improve yield, quality, and resilience for a wide range of climates and adverse abiotic stresses. The challenge for Miscanthus breeding is to harness the diversity through selections of outstanding wild types, parents, and progenies over a short time frame to deploy hybrids that make a significant contribution to a world less dependent on fossil resources. Here are described the strategies taken by the Miscanthus breeding programme at Aberystwyth, UK and its partners. The programme built up one of the largest Miscanthus germplasm collections outside Asia. We describe the initial strategies to exploit the available genetic diversity to develop varieties. We illustrate the success of combining diverse Miscanthus germplasm and the selection criteria applied across different environments to identify promising hybrids and to develop these into commercial varieties. We discuss the potential for molecular selections to streamline the breeding process.

“…It has high photosynthetic efficiency (Beale & Long, 1997;Davey et al, 2017), and fertilizer, herbicide and pesticide demands are low due to its high nutrient recycling capacity, competitiveness against weeds after the establishment phase and absence of pests and diseases (Jones, 2020). To minimize competition with other land uses, miscanthus cultivation methods are being developed for marginal and/or contaminated lands (Pogrzeba et al, 2017) because miscanthus tolerates drought, heavy metals and salinity (Chen et al, 2017;Hastings, Clifton-Brown, Wattenbach, Mitchel, Stampfel, et al, 2009, Hastings et al, 2014Lewandowski et al, 2016;Rusinowski et al, 2019). It offers different habitats compared to annual arable crops and improves landscape biodiversity by enriching structural heterogeneity within intensively used agricultural areas.…”

“…Oxidative damage due to the formation of ROS under heavy metal stress such as Pb and Cd is one of the important toxic characteristics (Rusinowski et al, 2019). An increase in H 2 O 2 concentration in grape leaves under Pb stress and in maize and rice under Cd stress is revealed in earlier studies (Anjum et al, 2015; Huihui et al, 2020; Irshad et al, 2020; Wang et al, 2014).…”

Contaminations of heavy metals such as lead (Pb) and cadmium (Cd) in medicinal plants (MPs) not only restrict their safe consumption due to health hazards but also lower their productivity. Biochar amendments in the soil are supposed to immobilize the toxic metals, improve the soil quality, and agricultural productivity. However, the impact of biochar on growth attributes, metal accumulation, pharmacologically active compounds of MPs, and health risk is less explored. An experiment was performed on three medicinal plants [Bacopa monnieri (L.), Andrographis paniculata (Burmf.) Nees, and Withania somnifera (L.)] grown in a greenhouse in soil co‐contaminated with Pb and Cd (at two concentrations) without and with biochar amendments (2% and 4% application rates). The fractionation of Pb and Cd, plant growth parameters, stress enzymes, photosynthetic capacity, pharmacologically active compounds, nutrient content, uptake and translocation of metals, antioxidant activities, and metabolite content were examined in the three MPs. The accumulation of Pb and Cd varied from 3.25–228 and 1.29–20.2 mg kg−1, respectively, in the three MPs, while it was reduced to 0.08–18 and 0.03–6.05 mg kg−1upon biochar treatments. Plants grown in Pb and Cd co‐contaminated soil had reduced plant biomass (5%–50% depending on the species) compared to control and a deleterious effect on photosynthetic attributes and protein content. However, biochar amendments significantly improved plant biomass (21%–175%), as well as photosynthesis attributes, chlorophyll, and protein contents. Biochar amendments in Pb and Cd co‐contaminated soil significantly reduced the health hazard quotient (HQ) estimated for the consumption of these medicinal herbs grown on metal‐rich soil. An enhancement in secondary metabolite content and antioxidant properties was also observed upon biochar treatments. These multiple beneficial effects of biochar supplementation in Pb and Cd co‐contaminated soil suggested that a biochar amendment is a sustainable approach for the safe cultivation of MPs.
