gladiolus/nicotine

Tobacco rattle virus (TRV-K) was first identified in a symptomatic Gladiolus plant cultivated in Korea. We analyzed the TRV-K genome and compared its phylogeny with other TRV isolates. After constructing of a full-length genomic RNA2 strand clone, a complete sequence was generated from several

During May of 2008 (austral autumn), an uncharacterized disease was observed on Dieffenbachia picta (Lodd.) Schott and Aglaonema commutatum Schott in commercial greenhouses in Pontevedra (34°45'6″S, 58°42'42″W), Argentina. Affected plants showed irregular, brown lesions on leaves, approximately 15

CONCLUSIONS GhNPR1 shares similar functions as Arabidopsis NPR1 . Silencing of GhNPR1 in Gladiolus results in an enhanced susceptibility to Curvularia gladioli. We propose that GhNPR1 plays important roles in plant immunity. Gladiolus plants and corms are susceptible to various types of pathogens

Functional analysis of genes in gladiolus has previously been impractical due to the lack of an efficient stable genetic transformation method. However, virus-induced gene silencing (VIGS) is effective in some plants which are difficult to transform through other methods. Although the Tobacco rattle

A polyubiquitin promoter (GUBQ1) including its 5'UTR and intron was isolated from the floral monocot Gladiolus because high levels of expression could not be obtained using publicly available promoters isolated from either cereals or dicots. Sequencing of the promoter revealed highly conserved 5'
