    “…The transgenic plants showed no marked changes in abundances of other photosynthetic proteins or chlorophyll content. The steady‐state rates of electron transport and CO(2) assimilation did not differ between the plants with increased Rieske abundance and control plants, suggesting that Cytochrome b (6) f is not the only factor limiting electron transport in sorghum at high light and high CO(2) . …”

    “…The yellowing of duckweed leaves under Cd stress could be alleviated by an exogenous DA (10/20/50/100/200 μM) supplement, and 50 μM was the optimal concentration to resist Cd stress by reducing root breakage, restoring photosynthesis and chlorophyll content. In addition, 24 h DA treatment increased Cd content by 1.3 times in duckweed under Cd stress through promoting the influx of Cd(2+). …”

    “…Additionally, the leaf color of the Wuci 1 and Wuci 2 tetraploids changed from light to dark, with an initial decrease in chlorophyll content followed by an increase. In summary, this study established an effective method for inducing polyploids in R. roxburghii f. eseiosa, which could provide a foundation for the breeding and development of new genetic resources for R. roxburghii f. eseiosa and other R. roxburghii varieties in the future.…”
