“…Pigment contents, ROS, REC, MDA, CAT and POD were observed in the same quadrant, and ANOVA results showed an increasing trend under upwelling stress suggesting some homogeneity in the regulatory mechanism of these traits in the face of upwelling stress for three mangrove species (Behrooz Sarabi, 2022). Previous studies showed that plants respond differently to different temperatures under chilling stress (Ok et al, 2020;Wang et al, 2021). In our research, none of the mangrove species exhibited markedly different responses to variations in upwelling water temperatures, indicating that mangroves are not sensitive to temperature variations in upwelling stress compared to low air or water temperatures.…”

Mangroves are unique forest communities with an abundance of species, high productivity and high ecological, social and economic value. Evaluation of the stress resistance of mangrove plants has mainly focused on the effects of high salinity, heavy metals and flooding, with fewer studies evaluating resistance to upwelling stress. Mangrove species of Avicennia marina, Aegiceras corniculatum and Kandelia obovata were submitted to three temperature upwelling (5, 10 and 15°C) and several physiological and biochemical parameters were measured at six time points (0, 6, 12, 24, 72 and 168 h). The data demonstrated: a certain amount of damage occurred to mangrove plants in the face of prolonged upwelling; different mangrove plants have different response strategies to upwelling; mangrove plants are not sensitive to different upwelling temperatures; the resistance of mangrove plants to upwelling stress was in the following order: A. marina< K. obovata< A. corniculatum. Markers of damage such as relative electrical conductivity (REC), malondialdehyde (MDA) and reactive oxygen species (ROS) among all mangrove species were significantly higher with prolonged upwelling stress. The contents of photosynthetic pigments in all three mangrove species also increased. Superoxide dismutase activity (SOD) was maintained at a high level in both control and treatment groupss. By contrary, the change of peroxidase activity (POD) of A. marina and K. obovata was larger than that of A. corniculatum. Catalase activity (CAT) in A. marina and K. obovata significantly increased under upwelling at both 5 and 10°C while there was no obvious variation of CAT in A. corniculatum. Soluble protein and Soluble sugar contents showed no clear variation but stayed at fairly high levels. However, proline content in A. corniculatum significantly increased under long-term upwelling stress while this was not the case in the other two species. High correlation could be observed between A. marina and MDA, O2- and POD in PCA while A. corniculatum showed association with proline and soluble sugar. In conclusion, the ability of A. corniculatum to tolerate upwelling stress might be due mainly to increases in the activities of SOD and the inducing of proline biosynthesis, while, A marina and K. obovata tolerated upwelling stress by adjusting activity levels of SOD, POD and CAT. Segregation in both principal component analysis (PCA) and hierarchical cluster analysis (HCA) further indicated different tolerances and resistances to upwelling between the three species. Our study provides new insights into the stress response of mangroves to upwelling.

“…Potato (Solanum tuberosum L) is a crucial staple food in numerous countries, ranking fourth after rice, wheat, and corn. Globally, more than 2.1 × 10 8 ha are dedicated to potato cultivation (Volkogon et al, 2021;Wang et al, 2021). China, the world's largest potato producer, is followed by India and Russia.…”

IntroductionThe contamination of farmland soil with the heavy metal cadmium (Cd) has consistently been a globally recognized environmental issue, especially with the rapid development of the central part of the Hanjiang River basin. The Cd contamination has become increasingly serious, and the accumulation and translocation of Cd in the soil-crop system warrant further research.MethodsIn this study, representative yellowish-brown soil and limestone soil from Hubei Province in China, as well as five varieties of potato (Solanum tuberosum L), were selected to investigate Cd accumulation and transfer regulation from soil to plants using pot tests at varying Cd concentration levels.Results and discussionFor Eshu-12, Favorita, Huashu-6, Mira, and Zhongshu-5, the accumulation capacity of Cd in different parts exhibits a consistent pattern: Cdroot > Cdstem > Cdleaf > Cdtuber. The potato varieties exhibited distinct differences in Cd concentration, as follows: CdFavorita > CdMira > CdEshu-12 > CdHuashu-6 > CdZhongshu-5. The yellowish-brown soil demonstrated a higher accumulation and lower transport capacity to the plants of Cd, while limestone soil exhibited the opposite trend. The bio-concentration factor and transfer coefficients in yellowish-brown soil revealed significant (p < 0.05) accumulation and transformation of Cd in potatoes.Conclusion and recommendationsThis significant accumulation of Cd posed a higher risk of transfer through the food chain. Therefore, in the Hanjiang River basin, where Cd contamination is a concern, the cultivation of potatoes in limestone soil is more advisable than yellowish-brown soil to mitigate food safety risks.
