Пространственная ориентация живых организмов посредством зрительной сенсорной... И все же в последнее время в отношении зрительных пигментов насекомых получено много интересных данных. Так, стало известно, что зрительный пигмент насекомых имеет значительно меньший молекулярный вес (3000-4000), чем молекулярный вес зрительных пигментов позвоночных (27 000-28 000) (Heller, 1969), а следовательно, и диаметр молекулы зрительного пигмента насекомых значительно меньше – около 5 А против 40 – 50 А у позвоночных. Получены доказательства того, что в основе зрения многих насекомых (по-видимому, это справедливо для всех насекомых) лежит ретиналь, который был найден у пчелы, домашней мухи, некоторых прямокрылых, стрекоз, жуков, бабочек (Goldsmi h, 1958; Wolke , Bow ess a. Scheer, 1960; Briggs, 1961). При этом интересно, что Голдсмиту (Goldsmi h, 1958) удалось извлечь зрительный пигмент из сложного глаза пчелы не детергентамп, а простым фосфатным буфером; после освещения раствор зрительного пигмента обесцвечивался, освобождая ретиналь. В 1964 г. Голдсмит и Уорнер (Goldsmi h a. War er, 1964) четко доказали, что зрительная система рабочей пчелы строится на основе витамина А (ретинола); в темноте витамин А окисляется до ретиналя, а на свету ретиналь переходит в витамин А. | |
