Figure 1: Effects of antibiotics on survival of P. yezoensis gametophytic cells.
(A) Sensitivity to antibiotics of P. yezoensis gametophytic cells cultured in
ESL medium with antibiotics after 2 weeks. The sensitivity of the gametophytes
to each antibiotic is shown as + (observed) or – (not observed). (B)
The survival rate of P. yezoensis gametophytic cells in various concentrations
of antibiotics. The survival rate was measured by counting the living and dead
cells of gametophytes cultured in ESL medium containing antibiotics at 15ºC
with a cycle of 60 μmol m-2 s-1 irradiance for 10 h and darkness for 14 h for 2
weeks. Values are the mean ± SD (n = 30). |
