Phosphorylation of Tobacco mosaic virus movement protein (TMV-MP) at three carboxyterminal Ser/Thr sites negatively regulates TMV-MP gating function and viral spread in Nicotiana tabacum but not in Nicotiana benthamiana, indicating a host dependant inactivation strategy. Here, we examine the effect of mimicking carboxyterminal phosphorylation on cell-to-cell transport of TMV-MP protein itself i...

The capacity to form flower buds in thin-layer explants was studied in flowering plants of several species, cultivars, and lines of Nicotiana differing in their response to photoperiod. This capacity was found in all biotypes examined and could extend into sepals and corolla. It varied greatly, depending on genotype, source tissue and its developmental stage, and composition of the culture medi...

Polyphenols and triterpenes in leaves extracts from three Nicotiana speciesVenelina Popova, Tanya Ivanova, Albena Stoyanova, Violeta Nikolova, Tsveta Hristeva, Margarita Docheva, Nikolay Nikolov, Ivan Iliev

Nicotiana ingulba is returned to species level here. It illustrated from plants cultivated at the Royal Botanic Gardens, Kew, which were grown seeds collected in Uluru-Kata Tjuta National Park Northern Territory, Australia. Its taxonomic history, ecology, cytology, etymology and cultivation are discussed.

A distinct endogenous pararetrovirus (EPRV) family corresponding to a previously unknown virus has been identified in the genome of Nicotiana tomentosiformis, a diploid ancestor of allotetraploid tobacco (Nicotiana tabacum). The putative virus giving rise to N. tomentosiformis EPRVs (NtoEPRVs) is most similar to tobacco vein clearing virus, an episomal form of a normally silent EPRV family in N...

Availability of complete plastid genomes of ten solanaceous species, Atropa belladonna, Capsicum annuum, Datura stramonium, Nicotiana sylvestris, Nicotiana tabacum, Nicotiana tomentosiformis, Nicotiana undulata, Solanum bulbocastanum, Solanum lycopersicum, and Solanum tuberosum provided us with an opportunity to conduct their in silico comparative analysis in depth. The size of complete chlorop...
