    Simulated seawater flooding reduces oilseed rape growth, yield and progeny performance

    Of the many threats to global food security, one of the most pressing is the increased incidence of extreme weather events. In addition to extreme rainfall, a combination of global sea level rise and storm surge is likely to result in frequent episodes of seawater flooding in arable systems along low-lying coasts. Hanley et al. […] More

    Plants and flood risk in Annals of Botany

    Annals of Botany will have a Special Issue on Vulnerability to, and management of, plant communities in the face of increased flood risk. The increased likelihood of extreme weather events globally poses a major flood risk. As a result, many coastal and riparian habitats, and the plant communities they contain are now valued for their […] More

  • Correlation between the expression ratio (flooded/unflooded) of ZmPgb1.1 and ZmPgb1.2 in relation to the ability of the genotypes to retain photosynthetic rates after 10 d of flooding.

    Elevating expression of phytoglobins enhances photosynthetic response of root-flooded maize

    Decreased crop photosynthetic rates are a major consequence of root flooding as severe perturbations of the photosynthetic machinery result from elevated levels of reactive oxygen species (ROS). Phytoglobins (Pgbs) are ubiquitous proteins induced by several types of stress that affect plant response by modulating nitric oxide. Youssef et al. demonstrate that elevating the expression of […] More

    SPECIAL ISSUE: Plant Responses to Low-Oxygen Environments

    AoB PLANTS is pleased to announce the publication of a Special Issue entitled Plant Responses to Low-Oxygen Environments, edited by Michael Jackson (University of Bristol, UK) and Abdelbagi Ismail (International Rice Research Institute, Philippines). Flooding and submergence impose widespread and unpredictable environmental stresses on plants and depress the yield of most food crops. The problem is increasing, […] More

  • Effects of submergence and de-submergence on a clonal plant

    Effects of submergence and de-submergence on a clonal plant

    Submergence and de-submergence are common phenomena encountered by riparian plants as water levels fluctuate, but little is known about the role of physiological integration in the adaptation of clonal plants to such conditions. Luo et al. study Alternanthera philoxeroides (alligator weed) after 30 days of submergence and find that connections between submerged and non-submerged ramets […] More

    Flooding and fragment size interact to determine survival and regrowth after fragmentation in two stoloniferous Trifolium species

    Clonal plants are common in frequently flooded habitats because of their resilience to disturbance. In a new study published in AoB PLANTS, Huber et al. investigated whether submergence prior to fragmentation of clones of two clover species reduced survival and regrowth of clonal fragments, and whether these fitness parameters differed between genotypes from highly disturbed […] More

  • Contrasting flooding tolerance strategies in Rorippa

    Contrasting flooding tolerance strategies in Rorippa

    Differential responses of closely related species to submergence can provide insights into the evolution and mechanisms of submergence tolerance. Akman et al. study two species of yellow cress, Rorippa amphibia and R. sylvestris, that can survive months of submergence and determine that R. amphibia elongates its stem to reach the water surface at the expense of […] More

    What happens now to agriculture in Japan?

    There’s an interesting post on Alex Tiller’s Blog on Agriculture and Farming that I missed earlier. Alex asks Will Agriculture in Japan Survive? It’s a timely question as the recent tsunami hit over 10% of rice-producing areas in Japan. As Alex points out there really isn’t a lot of room to expand agriculture because Japan […] More

  • Post-submergence recovery dynamics of wetland plants

    Post-submergence recovery dynamics of wetland plants

    Post-submergence recovery dynamics of wetland plants Fast growth recovery post-submergence is important for establishment of riparian species in zones where water level fluctuates. Luo et al. investigate recovery patterns of two wetland plants, Alternanthera philoxeroides and Hemarthria altissima, characterized by ‘escape’ and ‘quiescence’ strategies of flood tolerance, respectively. They find that a stem-elongation escape strategy […] More

    Oxygen transport via aerenchyma in soybean

    When in flooded soil, soybean, Glycine max, produces aerenchyma and hypertrophic stem lenticels. Shimamura et al. (pp. 277–284) investigate the oxygen dynamics in these tissues and find that hypertrophic lenticels on the stem of soybean, just above the water surface, are entry points for O2, and these connect to aerenchyma and enable O2 transport into […] More
