Radial Oxygen Loss from Plant Roots-Methods.

Plants (Basel) 2021 Oct 28;10(11). Epub 2021 Oct 28.

Laboratory of Plant Genetics and Breeding, Graduate School of Bioagricultural Sciences, Nagoya University, Furo-cho, Chikusa, Nagoya 464-8601, Japan.

In flooded soils, an efficient internal aeration system is essential for root growth and plant survival. Roots of many wetland species form barriers to restrict radial O loss (ROL) to the rhizosphere. The formation of such barriers greatly enhances longitudinal O diffusion from basal parts towards the root tip, and the barrier also impedes the entry of phytotoxic compounds produced in flooded soils into the root.

Plant-environment microscopy tracks interactions of with plant roots across the entire rhizosphere.

Proc Natl Acad Sci U S A 2021 Nov;118(48)

Ecological Sciences, The James Hutton Institute, Dundee DD2 5DA, United Kingdom;

Our understanding of plant-microbe interactions in soil is limited by the difficulty of observing processes at the microscopic scale throughout plants' large volume of influence. Here, we present the development of three-dimensional live microscopy for resolving plant-microbe interactions across the environment of an entire seedling growing in a transparent soil in tailor-made mesocosms, maintaining physical conditions for the culture of both plants and microorganisms. A tailor-made, dual-illumination light sheet system acquired photons scattered from the plant while fluorescence emissions were simultaneously captured from transparent soil particles and labeled microorganisms, allowing the generation of quantitative data on samples ∼3,600 mm in size, with as good as 5 µm resolution at a rate of up to one scan every 30 min.
