Abstract: Abstract of thesis entitled ASSIMILATION OF PHYTATE-PHOSPHORUS BY PLANTS Submitted by LUNG SHIU CHEUNG for the degree of Master of Philosophy at The University of Hong Kong in August 2005 Terrestrial plants generally meet their phosphorus (P) requirement by the uptake of inorganic phosphate (P ). A large proportion of soil P exists as organic compounds, of which phytate (IHP) is the dominant form. Although plants have the innate ability of acid phosphatase (APase) secretion to mineralize organic P compounds, no capability of soil phytate-P assimilation by plants has been evident. The first part of this study aimed to investigate the assimilation of external phytate-P by Nicotiana tabacum. Secreted phytase activity was substantially boosted -1 by 10-fold reduction in P supply to up to 0.6 U mg protein. While phytate adsorbed 2+ 2+ to sand could not be utilized, plant growth on phytate preformed with Mg and Ca ions was evident. Compared to Ca-IHP, Mg-IHP was a better P source, presumably due to its higher solubility. It is concluded that the major constraint that limits phytate-P assimilation is the rare occurrence of soluble phytate in soil. The second part of this study aimed to generate transgenic Nicotiana tabacum that secreted a β-propeller phytase (BPP). In sterile hydroponic culture using 1 mM Na-IHP as the sole P source, the transgenic lines accumulated 1.7-2.2 fold more shoot biomass than wild-type, concomitant with a 27-36% increase in shoot P concentration. However, recombinant phytase exudation did not satisfy plant P requirement when phytate solubility was constrained in sand culture. To enhance P utilization of plants, it is suggested that recombinant phytase exudation should be accompanied by some means for phytate solubilization, for instance, organic anion exudation.
