“…Climate changes are also characterized by soilrelated waterlogging complications due to natural factors or by human activities such as excessive irrigation and low drainage (Smethurst et al 2005). Waterlogging leads to a decreased O 2 availability in the soil with possible accumulation of phytotoxins, leaf chlorosis, stomatal closure (Wei et al 2018) and restricted crop performance by decreasing soil mineral nutrient accessibility (Ashraf 2012). When Medicago sativa was exposed to flooding stress, a marked reduction in leaf and root nutrient accumulation (B, Cu and Zn) was observed.…”

Background Global climate is changing more rapidly than ever, threatening plant growth and productivity while exerting considerable direct and indirect effects on the quality and quantity of plant nutrients. Scope This review focuses on the global impact of climate change on the nutritional value of plant foods. It showcases the existing evidence linking the effects of climate change factors on crop nutrition and the concentration of nutrients in edible plant parts. It focuses on the effect of elevated CO 2 (eCO 2), elevated temperature (eT), salinity, waterlogging and drought stresses, and what is known regarding their direct and indirect influence on nutrient availability. Furthermore, it provides possible strategies to preserve the nutritional composition of plant foods under changing climates. Conclusions Climate change has an impact on the accumulation of minerals and protein in crop plants, with eCO 2 being the underlying factor of most of the reported changes. The effects are clearly dependent on the type, intensity and duration of the imposed stress, plant genotype and developmental stage. Strong interactions (both positive and negative) can be found between individual climatic factors and soil availability of nitrogen (N), potassium (K), iron (Fe) and phosphorous (P). The development of future interventions to ensure that the world's population has access to plentiful, safe and nutritious food may need to rely on breeding for nutrients under the context of climate change, including legumes in cropping systems, better farm management practices and utilization of microbial inoculants that enhance nutrient availability.

“…For example, research on seedlings of silver birch ( Betula pendula Roth) suggested that waterlogging caused by long-term extreme precipitation promoted the formation of thin roots and increased the high density of non-glandular trichomes and leaves, which suggests an adaptive mechanism with respect to excess soil water [ 5 ]. Similarly, due to impaired functions of root systems, waterlogging also reduced accumulation and remobilization of carbohydrates into grains, grain yield production, and grain quality of wheat [ 6 ]. Furthermore, in the wetland ecosystem of China, flooding not only affected the reproduction phenology of Sinojackia huangmeiensis but could also respond to extreme precipitation-induced waterlogging by changing both seed morphological traits and element concentrations [ 7 ].…”

Future climate is projected to increase in the intensity and frequency of extreme precipitation events, and the resulting ecological consequences are often more serious than those of normal precipitation events. In particular, in desert ecosystems, due to the low frequency and strong fluctuation of extreme precipitation, the destructive consequences for desert plants caused by extreme precipitation have not received enough attention for some time. Based on statistics of extreme precipitation events (1965–2018) in the Gurbantunggut Desert, we investigated the effects of extreme precipitation (+0%, CK; +50%, W1; +100%, W2; +200%, W3; maintenance of field capacity, W4) on the plant life-history of the spring-germinated (SG) and autumn-germinated (AG) ephemeral plant Erodium oxyrhynchum by monitoring seedling emergence, survival, phenology, organ size, biomass accumulation, and allocation. The results showed that extreme precipitation caused about 2.5% seedling emergence of E. oxyrhynchum in autumn 2018 and 3.0% seedling emergence in early spring 2019, which means that most seeds may be stored in the soil or have died. Meanwhile, extreme precipitation significantly improved the survival, organ size, and biomass accumulation of SG and AG plants, and W3 was close to the precipitation threshold of SG (326.70 mm) and AG (560.10 mm) plants corresponding to the maximum individual biomass; thus, AG plants with a longer life cycle need more water for growth. Conversely, W4 caused AG plants to enter the leaf stage in advance and led to death in winter, which indicates that extreme precipitation may not be good for AG plants. Root and reproduction biomass allocation of SG and AG plants showed a significantly opposite trend under extreme precipitation treatments, which might be related to their different life-history strategies. Therefore, when only taking into account the changing trend of extreme precipitation from the Coupled Model Intercomparison Project 6 (CMIP6) climate projections data, we speculate that extreme precipitation may promote the growth of SG and AG plants from the beginning to the middle of this century, but extreme precipitation in autumn exceeding a certain threshold may adversely affect the survival of AG plants at the end of the century.

“…The total number of individuals is less than 600 (Wang et al., 2018), and it is one of the 120 wild plant species with extremely small populations in China. Due to the extremely narrow distribution range and extensive human disturbances, it has a high risk of extinction (Wei et al., 2018). The flowering season is from March to April, and bisexual flowers are primarily visited by several fly and bee species (Zhang et al., 2008).…”

Ex situ conservation is an effective approach to prevent the extinction of endangered species. Biotic interactions (e.g. herbivory and pollination) are critical to ex situ conservation success, including plant establishment, survival and reproduction. However, shifts in biotic interactions between wild and ex situ populations are still poorly understood. We compared herbivory and pollination characteristics between the only wild population (WP) and three ex situ populations (LP, local population, nearby WP; NP, north population, ca. 850 km; and SP, south population, ca. 750 km) of a critically endangered tree species (Sinojackia huangmeiensis) to explore the latitudinal changes in plant‐invertebrate interactions. Larvae of the Limacodidae family were the dominant herbivores in WP, LP and NP, while the only herbivore observed in SP was snail. Compared to WP, the leaf herbivory rate was unchanged in LP but decreased in NP and SP. Leaf defence traits (total phenols, tannins, leaf thickness and leaf dry matter content) increased or remained unchanged in the three ex situ populations. A pollinator (Apis cerana) of S. huangmeiensis was present in the four populations. NP and SP lacked some pollinators that were found in both WP and LP, but they shared one pollinator that was not observed in WP and LP. The pollinator visiting frequency increased in SP, while it did not change significantly in LP and NP. Synthesis and applications. Our results suggested that both herbivory and pollination of Sinojackia huangmeiensis changed in ex situ populations, with complete or partial changes in herbivores, leaf herbivory rate, pollinators, pollinator visiting frequency and fruit set in the two distant ex situ populations. This work provides a unique empirical study of shifts in both antagonistic and mutualistic biotic interactions between wild and ex situ populations. We emphasized that it is essential to integrate herbivore and pollinator management in future ex situ conservation of plant species.
