Eff ects of methyl jasmonic acid on morphogenesis of tobacco glandular and non-glandular trichomes
摘要
Abstract
In order to understand the role of jasmonic acid (JA) in the development of tobacco trichome, two genotypes of tobacco (Nicotiana tabacum L.), high glandular T.I.1068 (Tobacco introduction 1068) and non-glandular T.I.1112 (Tobacco introduction 1112) were treated with methyl jasmonic acid (MeJA) under sterile condition. Morphological changes of trichomes on leaf and stem were microscopically observed three weeks after MeJA treatment. Results showed: (1) T.I.1068 possessed only glandular trichomes of long stalk and short stalk. Once treated with MeJA, trichome density increased and was positively correlated with MeJA concentration, while no trichome type changes were observed. (2) T.I.1112 consisted of mainly non-glandular trichomes and short stalk glandular trichomes. When treated by MeJA, the occurrence of long stalk glandular trichome was observed, and their density increased consistently with MeJA concentration, but not for other two types. These results showed that MeJA specifically induced the initiation of long stalk glandular trichome both on glandular and non-glandular tobacco genotypes. It was indicated that the morphogenesis of diff erent trichome types of tobacco were regulated by diff erent network.关键词
