The aim of this study was to determine the antioxidant activity as well as total phenol (TPC) and total flavonoid content (TFC) in two fruits, Solanum anguivi and Solanum incanum grown in Darjeeling Himalaya and used as vegetables in Nepali recipes. The antioxidant activities were examined by five different methods namely DPPH free radical scavenging activity, reducing power, iron chelation, an...

Background: Over the past few decades, there has been more interest in geminiviruses, especially begomoviruses, as many of the diseases they cause have now reached epidemic proportions. Weed plants serve as an alternative host for begomoviruses and may allow the transmission of begomovirus to other horticulture crops and medicinal plants thus enhances the host range of these viruses in differen...

Chromosome pairing relationships within cultivated potato (Solanum tuberosum) and its wild tuber-bearing relatives (Solanum sect. Petota) have been interpreted by genome formulas, developed in the early 1900s, through techniques of classic meiotic analysis of interspecifi c hybrids. Here we reexamine potato genome hypotheses with the fi rst phylogenetic analysis of all major genomes of sect. Pe...

Mechanism of microtuberization in three elite cultivars kufri badhsha (KB), kufri chandramukhi (KCM) and kufri jawahar (KJ) of potato was studied. Sprouts of all the three cultivars were used to obtain in vitro shoot cultures. MS medium supplemented with chlorocholine chloride was found to be most suitable for all the cultivars. Maximum tuberization was obtained under incubation conditions of c...

Figure 1. Fruits propagated by bowerbirds. (A) Solanum ellipticum plant and fruit. Scale in cm. (B) Established bower surrounded by Solanum plants. (C) Mean (±1 s.e.) numbers of Solanum plants in 2010 at: randomly selected sites within the study area (n = 20); new bower sites that were being used for the first time (n = 11); established bower sites that had been used for more than one year (n =...

in order to better understand how to prevent enzymatic greenning, it is important to understand  kinetic properties of polyphenol oxidase.  we investigated the effect of sds on the rate of catechol oxidation by small cherry tomato partial purified ppo. ppo activity increased with increasing sds concentration. the most effective concentration of sds was 0.8, 1 and 1.25 mm in according to ph and ...

The natural history of epiphytic plant species has been extensively studied. However, little is known about the physiology and genetics of epiphytism. This is due to difficulties associated with growing epiphytic plants and the lack of tools for genomics studies and genetic manipulations. In this study, tubers were generated from 223 accessions of 42 wild potato Solanum species, including the e...
