Cadmium and arsenic affect root development in Oryza sativa L. negatively interacting with auxin [PDF]

, 2018
Cadmium (Cd) and arsenic (As), non essential, but toxic, elements for animals and plants are frequently present in paddy fields. Oryza sativa L., a staple food for at least the half of world population, easily absorbs As and Cd by the root, and in this ...

Root canal morphology of mandibular premolars

The Journal of the American Dental Association, 1978
Four hundred mandibular first premolars and 400 mandibular second premolars were decalcified, injected with dye, and made transparent to determine the number of root canals, their type, the ramifications of the main root canal, the location of apical foramina and transverse anastomoses, and the frequency of apical deltas.

Root morphology and exudate availability are shaped by particle size and chemistry in Brachypodium distachyon

Plant Direct, 2020
Root morphology and exudation define a plants’ sphere of influence in soils. In turn, soil characteristics influence plant growth, morphology, root microbiome, and rhizosphere chemistry. Collectively, all these parameters have significant implications on
