A promoter is an essential structural component of a gene that controls its transcription activity in different development stages and in response to various environmental stimuli. Knowledge of promoter functionality in heterologous systems is important in the study of gene regulation and biotechnological application. In order to explore the activity of the pepper capsaicin synthase gene (PUN1)...

The tropical armyworm, Spodoptera litura (F.) (Lepidoptera: Noctuidae), is an important pest of tobacco, Nicotiana tabacum L. (Solanales: Solanaceae), in South China that is becoming increasingly resistant to pesticides. Six potential trap crops were evaluated to control S. litura on tobacco. Castor bean, Ricinus communis L. (Malpighiales: Euphorbiaceae), and taro, Colocasia esculenta (L.) Scho...

Galactinol synthase (GolS) is a key enzyme in raffinose family oligosaccharide (RFO) biosynthesis. The finding that GolS accumulates in plants exposed to abiotic stresses indicates RFOs function in environmental adaptation. However, the evolutionary relationships and biological functions of GolS family in rapeseed (Brassica napus) and tobacco (Nicotiana tabacum) remain unclear. In this study, w...

Ralstonia solanacearum FJAT-91, which displays higher virulence toward plants belonging to the family Solanaceae, was isolated from a wilted tomato plant vessel in Fujian province, southeast China. Here, we report the complete genome sequence of R. solanacearum FJAT-91 using long-read single-molecule PacBio sequencing technology. The genome comprises a 3,873,214-bp circular chromosome and a 2,0...

Premise of research. Brood-site deceptive flowers use dishonest signals—especially floral odors that mimic oviposition substrates—to attract and deceive saprophilous insects to pollinate them. In this work, we recorded the pollinators of the sapromyiophilous species Jaborosa rotacea (Solanaceae) endemic to southern South America. Then, we characterized the floral volatiles of this species, and ...

Tetranychus evansi Baker & Pritchard, 1960 (Tetranychidae) is a phytophagous mite with wide distribution and high importance for agriculture. This study reports the occurrence of T. in Nicotiana alata Link Otto, forgetiana Sander ex W. Watson (Solanaceae) their putative hybrids greenhouse Rio Grande do Sul state, Brazil. Different stages development were found N. hybrids.
