“…A number of plant viruses have been shown to cause increased respiration in infected host cells (Weintraub, Ragetli, and Dwurazna 1964;Merrett and Bailey 1969). The enlargement of mitochondria and development of cristae caused by infection with LMV and BYMV may be morphological expressions of an increased capacity for respiration.…”

Although lettuce mosaic virus (LMV) has been studied from many points of view, as summarized by Tomlinson (1970), there has been no published record of the effects of this virus on the fine structure of its host's cells. Edwardson (1966) noted that LMV induced cytoplasmic inclusions in host cells but did not record any effects on organelles. This communication reports the effects of LMV on fine structure of mesophyll cells of C. quinoa. Materials and MethodsGlasshouse-grown seedlings of O. quinoa were mechanically inoculated on the three lower leaves with sap from lettuce (Lactuca 8ativa L.) seedlings infected with LMV. After 8-9 days the inocula.ted leaves developed yellow local lesions and 17 days after inoculation the younger leaves of the new growth had developed areas of yellow tissue (systemic symptoms). Uninoculated plants were grown under the same conditions as the inoculated plants, as controls.Seventeen days after inoculation samples were taken from the centres of local lesions, from green tissue on the same leaves, from the centres of yellow systemically infected tissue, from the centres of green areas on systemically infected leaves, and from comparable leaves on the control plants.Tissue pieces were fixed in 3% glutaraldehyde, post-fixed in 2% OS04, both in phosphate buffer. Samples were then stained for 1 hr in 2% uranyl acetate in water, dehydrated in a graded ethanol series, and embedded in Durcupan ACM. Sections were cut with glass knives, stained for 8-9 min in lead citrate (Reynolds 1963), and examined in a Philips EM 300 electron microscope at 60 kV. Observations were made on three blocks from each tissue type.

“…The alteration of nuclear morphology and the close association of inclusions with the nucleus suggest that the nucleus in involved in their synthesis. The appearance of large numbers of mitochondria near affected nuclei suggest that these organelles are also involved, and this is probably a morphological expression of the increased respiration that frequently occurs in virus-infected tissues (WEINTRAUB, RAGETLI andDWURAZNA 1964, MERETT andBAILEY 1969).…”

“…The contradictory effects of virus infection on catabolic glucose metabolism in the whole leaf tissues that gave systemic disease without necrotic local lesions have been presented by several investigators (MERRETT and BAYLEY 1969). Thus it becomes apparent in part that there are no dianges in the activities of the pentose phosphate pathway between infected and uninfected leaf tissues whidi is presented by taking advantages of isotope methods (BELL 1964, BAUR, HALLIWELL and LANGSTON 1967, BOZARTH 1969 and tests of enzyme activities (FARKAS and KIR.4LY 1962).…”

“…As to early dissimilation of glucose in the systemically infected leaf epidermal tissues, it has not been fully investigated so far, although other systemic infection systems using whole leaf tissues present contradictory arguments (MERRETT and BAYLEY 1969). Because of the possible implication of oxidative metabolism in virus-infected leaf epidermis, the nature of the enzymes involving in the pentose phosphate pathway must be examined.…”
