Application of genetics and genomics towards Capsicum translational research

Abstract: Capsicum species commonly known as Chili peppers are economically important group of plants belonging to the Solanaceae family. Of the 38 species reported, only six species namely, Capsicum annuum, C. assamicum, C. baccatum, C. frutescence, C. chinense and C. pubescens are cultivated. They are very important component of the human being as peppers are used as vegetables, spices, and a coloring agent and for medicinal purposes. Based on pungency trait which is due to the presence of a group of compounds known as capsaicinoids, cultivated capsicums are classified into sweet peppers and hot peppers. Although conventional breeding and classical genetic analysis were successful in estimating the number of genes for economically important traits governed by few major genes and their incorporation in the breeding programme, the advent of molecular markers and recently developed next generation sequencing technologies supplemented greatly in dissecting the genetic and molecular basis of economically important traits in the capsicum genome for applied research. Here in this review, we tried to highlight the use of molecular markers, comparative mapping and advanced genomics technologies and their integrated use in the translational research of cultivated Capsicums.

Bioremoval of Cu(II), Zn(II), Pb(II) and Cd(II) by Nostoc muscorum isolated from a coal mining site

Abstract: This study evaluated the potential of the cyanobacterium Nostoc muscorum isolated from a mining environment for the removal of the heavy metals Cu(II), Zn(II), Pb(II) and Cd(II) from a constituent aqueous solution of different initial concentrations (5 to 50 mg L−1). Prior to the metal bioremoval experiments, the effect of three main culture parameters, i.e. inoculum volume, inoculum age and pH, on N. muscorum growth was assessed and their levels optimized employing the Taguchi experimental design technique. The batch metal removal kinetics showed a maximum removal of Pb(II) (98 %) and Cu(II) (87.8 %), followed by Cd(II) (82 %) and Zn(II) (67.2 %) at 5 mg L−1 initial metal concentration. Furthermore, estimation of protein, carbohydrate and biomass contents of the metal-exposed N. muscorum revealed that Zn(II) and Cd(II) are more toxic compared to Cu(II) at all initial metal concentrations, whereas it was more tolerant towards Pb(II).

A Convenient Trans Diastereoselective Synthesis of 3-Butadienylazetidinones and Their Diels−Alder Cycloaddition Reactions

Abstract: An efficient trans diastereoselective synthesis for azetidinones 3 having 3-dienyl functionalities was developed. The method first involved the [2 + 2] cycloaddition of butadienylketene with variou...

Surplus Labour, Social Structure and Rural to Urban Migration: Evidence from Indian Data

Abstract: This paper examines the empirical implications of the Lewis Model with respect to the relationship between the phenomenon of surplus labour in rural areas and out-migration from these areas to urban areas. It does so by using a micro-economic data set of migrants and non-migrants for India. We find strong empirical support for the key prediction of the Lewis Model that rural-urban migration will be influenced by the existence of surplus labour in the rural areas where the migrants originate. We also find that the phenomenon of rural-urban migration is more complex than viewed within a simple Lewis framework. Social structure and the possession of human capital are important determinants of rural-urban migration – individuals from scheduled castes and scheduled tribes and those with little or no education are less likely to migrate to urban areas. Given that scheduled castes and scheduled tribe households along with households with low levels of educational attainment are more likely to be poor, our findin...
