Consistency of Nicotiana attenuata's herbivore- and jasmonate-induced transcriptional responses in the allotetraploid species Nicotiana quadrivalvis and Nicotiana clevelandii.
We examined the consistency of the native diploid Nicotiana attenuata (Na)'s herbivore-induced transcriptional changes in the two allotetraploid natives, Nicotiana clevelandii (Nc) and Nicotiana quadrivalvis (Nq), which are thought to be derived from hybridizations with an ancestral Na. An analysis of nuclear-encoded chloroplast-expressed Gln synthetase gene (ncpGS) sequences found strong simil...
متن کاملThe jasmonate-induced expression of the Nicotiana tabacum leaf lectin.
Previous experiments with tobacco (Nicotiana tabacum L. cv Samsun NN) plants revealed that jasmonic acid methyl ester (JAME) induces the expression of a cytoplasmic/nuclear lectin in leaf cells and provided the first evidence that jasmonates affect the expression of carbohydrate-binding proteins in plant cells. To corroborate the induced accumulation of relatively large amounts of a cytoplasmic...

Manduca sexta recognition and resistance among allopolyploid Nicotiana host plants.
Allopolyploid speciation occurs instantly when the genomes of different species combine to produce self-fertile offspring and has played a central role in the evolution of higher plants, but its consequences for adaptive responses are unknown. We compare herbivore-recognition and -resistance responses of the diploid species and putative ancestral parent Nicotiana attenuata with those of the two...
متن کاملJasmonate perception regulates jasmonate biosynthesis and JA-Ile metabolism: the case of COI1 in Nicotiana attenuata.
CORONATINE INSENSITIVE 1 (COI1) is a well-known key player in processes downstream of jasmonic acid (JA) biosynthesis: silencing COI1 in Nicotiana attenuata (ir-coi1) makes plants insensitive to JA, prevents the up-regulation of JA-mediated defenses and decreases the plant's resistance to herbivores and pathogens. In agreement with previous studies, we observed that regulation of several JA bio...
