molecular evolution of a host-range gene in geminiviruses infecting asexual populations of eupatorium makinoi.asexual plants of eupatorium makinoi is frequently infected with tobacco leaf curl geminivirus (tlcv). the host range of tlcv is narrow, and orf c4 is considered to function as a host range determinant. using this tlcv-eupatorium system, we tested the expectation that the rate of amino acid replacements will be accelerated in orf c4 if resistant genes of the host plants drive molecular evolution in orf c4. orf c4 is entirely contained within a longer orf c1 encoding a replication protein. we ana ...19989794079
effects of virus infection and light environment on population dynamics of eupatorium makinoi (asteraceae).we studied the effects of virus infection on dynamics of three eupatorium makinoi populations in contrasting light environments, gora-dani (a shaded population) and minou 1 and minou 2 (open-site populations). censuses of the plants were taken for 8 yr in gora-dani and 4 yr in minou 1 and minou 2. after the epidemics of virus infection, most plants were virus infected at both sites. the number of plants and the proportion of flowering individuals decreased rapidly and simultaneously in the shade ...200111302846
effects of virus infection and growth irradiance on fitness components and photosynthetic properties of eupatorium makinoi (compositae).we examined the effects of geminivirus infection on fitness components and on photosynthetic properties of the host plant, eupatorium makinoi, grown at two irradiance levels in a natural-light greenhouse. under the low-light condition (13% full sunlight), more than a half of the infected plants died during the 9-mo experiment, while most of uninfected plants survived. growth rate was also lowered by infection. at high light (50% full sunlight), by contrast, virus infection did not cause mortalit ...199721708634
