“…Climate warming may affect the metabolism of plants, increase the defense substances and promote the invasion of weeds ( Rice et al., 2021 ). In the present study, increased content of defensive substances was present in the roots of toxic plants in a degraded alpine grassland on the Qinghai-Tibetan Plateau.…”

“…[ 1‐2 ] According to the National Oceanic and Atmospheric Administration (NOAA) monitoring data, the concentration of CO 2 in the atmosphere has reached 419 ppm. [ 3 ] Therefore, there is an urgent need to solve the environmental problems caused by CO 2 . The reduction of CO 2 using natural energy sources can not only solve the above problems in a sustainable manner, but produce available chemicals or fuels.…”

Comprehensive SummaryPhotocatalytic CO2 reduction to fuels and chemicals has been considered as the promising avenue to realize carbon resource recycling. Covalent organic frameworks (COFs) with pre‐designed and tailorable structures are promising platforms for studying the influence of the microenvironment of catalysts on photocatalytic CO2 reduction. Herein, we report three isomorphic COFs (TPHH‐COF, TPPD‐COF and TPBD‐COF) as heterogeneous photocatalysts for CO2 reduction and investigate the different levels of conjugation and planarity of COFs effect on the catalytic activity. Photoelectrochemical measurements show that TPPD‐COF has a narrower band gap and faster photocurrent response compared to TPHH‐COF and TPBD‐COF, probably due to the moderate conjugation and planarity. As the photocatalyst, TPPD‐COF showed the most outstanding photocatalytic activity with the production rates of 951 and 157 μmol·g–1·h–1 for CO and H2, respectively. This study illustrates the close relation between microenvironment and photocatalytic activity and provides new insights for designing high‐performance photocatalysts.

“…One key signal that affects stomatal movement and development is the concentratio n of atmospheric CO2 (reviewed in Zhang et al, 2018;Engineer et al, 2014). The concentration of CO2 in the atmosphere is continuing to rise and there has been considerable effort made to understand the impact of this increase on plant growth and productivity (Rice et al, 2021;Danielle et al, 2021). In the context of the work described here, one of the consequences of an increase in atmospheric CO2 concentration is a decrease in the accumulation of mineral micronutrients in the aerial parts of the plant, including the seed (Myers et al, 2014;Hepworth et al, 2015).…”

Countering elevated CO₂ induced Fe and Zn reduction in Arabidopsis seeds

Growth at increased concentrations of CO 2 induces a reduction in seed zinc (Zn) and iron (Fe). Using Arabidopsis thaliana, we investigated whether this could be mitigated by reducing the elevated CO 2 -induced decrease in transpiration.We used an infrared imaging-based screen to isolate mutants in At1g08080 that encodes ALPHA CARBONIC ANHYDRASE 7 (ACA7). aca7 mutant alleles display wild-type (WT) responses to abscisic acid (ABA) and light but are compromised in their response to elevated CO 2 .ACA7 is expressed in guard cells. When aca7 mutants are grown at 1000 ppm CO 2 they exhibit higher transpiration and higher seed Fe and Zn content than WT grown under the same conditions.Our data show that by increasing transpiration it is possible to partially mitigate the reduction in seed Fe and Zn content when Arabidopsis is grown at elevated CO 2 .
