Nitrogen stock and farmer behaviour under rice policy change in Japan.

Mitigating the environmental impact of nitrogen (N) derived from agricultural production is a significant issue in our progression towards a sustainable society. This study aims to estimate the N stock (i.e.

Developmental changes in peanut root structure during root growth and root-structure modification by nodulation.

Background And Aims: Basic information about the root and root nodule structure of leguminous crop plants is incomplete, with many aspects remaining unresolved. Peanut (Arachis hypogaea) forms root nodules in a unique process. Structures of various peanut root types were studied with emphasis on insufficiently characterized lateral roots, changes in roots during their ontogenesis and root modification by nodule formation.

An improved method for clearing and staining free-hand sections and whole-mount samples.

Background And Aims: Free-hand sectioning of living plant tissues allows fast microscopic observation of internal structures. The aim of this study was to improve the quality of preparations from roots with suberized cell walls. A whole-mount procedure that enables visualization of exo- and endodermal cells along the root axis was also established.
