“…Light itself, therefore, has to be seen as a regulative factor on the effects of the virus. Light does not contain genetic information, but is able to trigger by the photosynthetic apparatus (BUCHANAN 1980) or by photoreceptors (MOHR 1980, ScHOPFER 1977, HARDING and SHROPSHIRE 1980 mediated subsequent reactions which produce the observed after-effects (THOMAS and STODDART 1980, SuNDQVisT et al 1980, WOLLGIEHN and PARTHIER 1980, PARTHIER 1982.…”

Various kinds of pathological effects of the Abutilon Mosaic Virus (AbMV) in seasonal dependency have been observed on the macroscopic as well as on the microscopic level. The annual rhythmic fluctuation of light caused by the varying length and intensity of light incidence is directly correlated with the realization of symptoms, leading to an intensification of the leaf mosaic and to an increase in the light leaf areas during the summer. These macroscopic observations are correlated with an annual change in the plastid fine structure in the mesophyll of the lightest areas of the leaf. The grana‐stroma‐organization of the plastids is completely eliminated through a reduction and disorganization in the thylakoid system during the spring and summer, restored in the autumn, and preserved over the winter. This change in the plastid fine structure is limited to the leaf mesophyll. The plastids of the leaf stem, like the plastids of non‐infected plants, do not display any change in their fine structure.

“…In certain algae grown in darkness and on media in which Chl synthesis is greatly reduced, Pchl was found also not to accumulate in measurable quantities (7). In conifers, dark conversion of Pchl to Chl varies from more or less complete in Pinus, intermediate in Picea, to rather incomplete in Larix (23). Further research on the effect of the herbicide in these plants forming Chl in darkness is very desirable.…”

“…Considering the above discussion, higher levels of GDH, GS and GOGAT activities in the hybrid are important since the hybrid possessed higher levels of chlorophyll-a and chlorophyll-b, and the male parent was the better parent (unpublished data). Participation of nitrogen nutrition in chlorophyll and chloroplast development, has been discussed by SuNDQViST et al (1980). HEDLEY and STODDART (1971) observed in Lolium first leaf that the treatment that increased or decreased chlorophyll contents, had similar effect upon the levels of GPT but were without any effect on GOT.…”

Changes in the activities of enzymes of ammonia assimilation viz., glutamate dehydrogenase (GDH), glutamine synthetase (GS) and glutamate synthase (GOGAT), together with the activities of glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT) were analysed in the topmost fully expanded leaf of pearl millet (Pennisetum americanum L. Leeke) hybrid BJ‐104, and its parents, J‐104 and 5141‐A, during the entire period of growth in field. Ammonia assimilation enzymes showed strong ontogenic trends and the hybrid attained activities either equal to the better (male) parent or showed better parental heterosis. In contrast to this both GOT and GPT activities were slightly higher than the poor (female) parent. The role of these enzymes in relation to chlorophyll synthesis and transport of metabolites from cellular compartments of C4 plants, are discussed. Surveying the literature on attempts to propose biochemical criteria for hybrid vigour, it is proposed that there cannot be a universal criterion, rather rate limiting steps in different cultivars should be searched.
