SummaryPrevious studies revealed that blue light stimulates and red light inhibits prehaustoria development in young seedlings of the parasitic weed Cuscuta campestris (field dodder). This study showed a positive correlation between blue light induced increases in inositol 1,4,5‐trisphosphate (IP3) and blue light‐mediation of prehaustoria development, prior to host attachment. Blue light induced a significant increase in the level of IP3, with a peak at about 30 min. Thereafter, the level of IP3 declined to the resting value after 2 h of blue light. Irradiation with 10 min red light pulse applied directly at the end of each 0.05, 0.1, 0.15, 0.2, 0.3, 1, 2 and 4 h blue light significantly reduced IP3, while high levels of IP3 were observed after 10 min far‐red pulse. The G‐protein inhibitor pertussis toxin inhibited prehaustoria developed under blue light, suggesting that receptor‐coupled G‐proteins are likely to be involved in prehaustoria development. These results are the first in vivo demonstration of a possible role for IP3 as a second messenger in the blue light signal transduction process in prehaustoria development in Cuscuta.
