Spatial-Related Community Structure and Dynamics in Phytoplankton of the Ross Sea, Antarctica

Frontiers in Marine Science, 2020
The Ross Sea exhibits the largest continental shelf and it is considered to be the most productive region in Antarctica, with phytoplankton communities that have so far been considered to be driven by the seasonal dynamics of the polynya, producing the ...

Exogenous ascorbic acid scarcely ameliorates inhibition of photosynthesis in rice leaves by O3

Plant Production Science, 2017
The role of ascorbic acid on acute O3-induced inhibition of photosynthesis in solution-cultured paddy rice was evaluated. As pre-treatment, ascorbic acid (0, 5, and 10 mM) was added to the culture solution for 5 d before 5 h of O3 exposure (0, .1, and .3
