| Résumé : | A study of the acction of Sm on the formation of chloroplasts by Hordeum vulgare: 1. confirmed the idea that Sm inhibits not only the synthesis of the chlorophylls, but also that of the chloroplasts themselves; 2. shows that Sm has a specific action on the development of the chloroplasts, attaining several chloroplastic constituents, whereas others are not touched (respiratory system for example). Barely seedlings which had formed white leaves as a consequence of the action of Sm are still able to produce normal green leaves when Sm is removed. Hence, Sm does not alter the hereditary properties of the higher plant studied, by provoking the mutation of nuclear genes nor by eliminating cytoplasmic units possessing genetic continuity. Sm inhibits the growth and the differentiation of proplastids into chloroplasts without preventing their multiplication. © 1995. |
