Abstract
There is evidence that the pectic polymer rhamnogalacturonan II (RGII) is cross-linked by borate diesters and these are involved in the control of cell- wall rigidity, plant growth and food texture. We will put these observations into a developmental context by imaging the distributions of boron and RGII in plants, and correlating RGII dimerisation with mechanical properties. We will test the hypothesis that apiogalacturonan segments are widespread trace pectic components and, like RGII, can be cross-linked by borate. We will look for abnormalities in boron metabolism, growth and development in Arabidopsis mutants defective in apiose synthesis.
