Figure 2

Comparison of L. gibba clone 7741 plants grown in media without ((a–c); upper row as a control) and with ((d–f); bottom row) salicylic acid (SA). (a) Control fronds grown in medium without SA showing high amount of biomass 15 days after inoculation. (b) Magnification of the red-squared region in (a) showing the absence of flowers. (c) Dissected budding pocket of a frond growing on SA-free medium; the white arrow indicates frond primordium, and the red arrow indicates flower primordium. (d) Fronds growing on medium supplemented with 20 µM SA showing lower amount of biomass after 15 days. (e) Magnification of the red-squared region in (d), showing flowers (red arrows); (f) Mature flower dissected from a budding pocket with pistil (red arrow), and two stamen (white arrows; anthers have shed).
