T. Matoh et al., UBIQUITY OF A BORATE RHAMNOGALACTURONAN-II COMPLEX IN THE CELL-WALLS OF HIGHER-PLANTS, Plant and Cell Physiology, 37(5), 1996, pp. 636-640
The presence of a borate-rhamnogalacturonan II (RG-II) complex [Kobaya
shi et al. (1996) Plant Physiol. 110: 1017] was examined in cell walls
of 24 species from higher plants. We studied two species in Brassicac
eae, three in Cucurbitaceae, four in Leguminosae, two in Apiaceae, two
in Chenopodiaceae, two in Solanaceae, two in Asteraceae, one in Lilia
ceae, one in Araeae, two in Amaryllidaceae and three in Gramineae. In
all the species examined, cell-wall boron was judged to be associated
with RG-II. Moreover, in 15 species it seemed likely that RG-II might
be the exclusive carrier of boron in the cell wall.
