<p>The relative change in PG species after introduction of <i>M. racemosa</i> to KM is the percentage value for the difference between the values of AS and KM, divided by the value of AS. An asterisk indicates that the value of KM is significantly different from that of AS (<i>P</i><0.05). Values are means ± standard deviation (<i>n</i> = 4 or 5).</p><p>Levels of PG molecular species in leaves of <i>M. racemosa</i> plants.</p
