Field microplot experiments were conducted from 1987 to 1992 to determine the relationship between fresh weight leaf yield of shade tobacco (Nicotiana tabacum) and initial density of Globodera tabacum tabacum (encysted J2 per cm(3) soil). Initial nematode densities of 0.1 to 1,097 J2/cm(3) soil were negatively correlated with leaf yield, total shoot weight, and normalized plant height 5 to 6 we...

BACKGROUND A linkage map consisting of 24 linkage groups has been constructed using simple sequence repeat (SSR) markers in Nicotiana tabacum. However, chromosomal assignments of all linkage groups have not yet been made. The Q chromosome in N. tabacum encodes a gene or genes triggering hybrid lethality, a phenomenon that causes death of hybrids derived from some crosses. METHODOLOGY/PRINCIPA...

Karue Ase's traditional rituals to the people in Labian Ira'ang have been performed for generations, but they are delivered orally from generation and never documented published. The purpose of this study is document describe Ase community. This uses survey methods. Data collection in-depth interview sheets field observations. analysis qualitative descriptive analysis. results showed that used ...

Abstract The novel and revolutionary approach to plant protection presented in this work, based on the preparation of bifunctional salts a resistance inducer combined with polyamine cation, may become potential solution future for reducing effects abiotic biotic stresses which is exposed. This study presents synthesis, physical properties, phytotoxicity, systemic acquired (SAR) induction effica...

Background Controlling infectious disease using medicinal plants is the oldest healthcare known to mankind. Regardless of the enormous advances observed in modern medicine, medicinal plants are still playing vital roles. However, only a small proportion of medicinal plants are examined for bioactive compounds which may vary in different factors. This study aimed to evaluate phytochemical consti...

RNA editing in plant organelles is mediated by site-specific, nuclear-encoded factors. Previous data suggested that the maintenance of these factors depends on the presence of their rapidly evolving cognate sites. The surprising ability of allotetraploid Nicotiana tabacum (tobacco) to edit a foreign site in the chloroplast ndhA messenger RNA was thought to be inherited from its diploid male anc...

Nicotiana otophora is a wild parental species of Nicotiana tabacum, an interspecific hybrid of Nicotiana tomentosiformis and Nicotiana sylvestris. However, N. otophora is least understood as an alternative paternal donor. Here, we compared the fully assembled chloroplast (cp) genome of N. otophora and with those of closely related species. The analysis showed a cp genome size of 156,073 bp and ...
