Abstract

Possible Role of Root Border Cells in Detection and Avoidance of Aluminum Toxicity by Susan C. Miyasaka, and Martha C. Hawes Plantphysiol Volume 125(4):1978-1987 April 1, 2001 ©2001 by American Society of Plant Biologists Relative root elongation of two snapbean cultivars (cv Dade and cv Romano) with increasing total Al levels after 96 h in CaCl2 solution (a; 0, 12.5, 25, and 50 μm) agarose gel (b; 0, 50, 100, and 200 μm). Miyasaka S, Hawes M. Plantphysiol 2001;125:1978-1987 ©2001 by American Society of Plant Biologists Border cell viability of two snapbean cultivars (cv Dade and cv Romano) exposed in situ to increasing levels of total Al (0, 50, 100, and 200 μm) in agarose gels after 96 h. Miyasaka S, Hawes M. Plantphysiol 2001;125:1978-1987 ©2001 by American Society of Plant Biologists Effect of Al exposure in situ on border cells of two snapbean cultivars a, cv Dade roots exposed to 0 Al in agarose with the blurring of border cells was due to dispersal of cells into solution; b, cv Romano roots exposed to 200 μm total Al in agarose with ...
