Possibilities of sweet potato [Ipomoea batatas (L.) Lam] value chain upgrading as revealed by physico-chemical composition of ten elites landraces of Benin
Sweet potato is one of the most important food security promoted root crops in the world, especially in sub-Saharan Africa. Unfortunately, the crop is still neglected and underutilized in Benin Republic. To establish baseline data for its better utilization for upgrading its value chain, 10 selected local varieties (01 cream, 02 white, 03 yellow, and 04 orange flesh-colored) were compared for their macro-nutritional...

Effect of osmotic stress on in vitro propagation of Musa sp. (Malbhog variety)
In vitro propagation of banana preferably use sword sucker as explant source where microbial contamination poses a great problem in establishment of aseptic cultures. This study demonstrates up to 36% reduced microbial contamination in aseptic culture establishment and subsequent micropropagation due to osmotic stress induction in the banana suckers. Osmotic stress was induced by keeping the freshly collected suckers in...

Development of putative transgenic lines of cassava variety H-226
Cassava production in India is drastically affected by cassava mosaic disease (CMD) caused by the Indian cassava mosaic virus (ICMV) and Sri Lankan cassava mosaic virus (SLCMV). An attempt was done to develop transgenic cassava lines resistant to SLCMV through RNAi vector targeting a conserved 440 bp of 5’ end of SLCMV Rep (AC1) gene which also overlaps with part of AC4 gene, and functions as a viral RNAi...

Determining water content and other impurities in Siparuna guianensis Aublet essential oil using differential scanning calorimetry
Siparuna guianensis Aublet is a predominant species in the Brazilian Cerrado. Some studies found that its essential oil has properties that could be useful for manufacturing new products. Its quality depends on physicochemical properties, since its degradation, as well as water content and other volatile materials may cause several changes in its features. The differential scanning calorimetry (DSC) was used to...

Antioxidant activity, phenolic and flavonoid contents of some wild medicinal plants in southeastern Algeria
This study reported on five plants known for their use in traditional medicine in southeastern Algeria, namely: Artemisia campestris, Asteriscus pygmaeus, Pituranthos chlorantus, Pallenis spinosa and Aizoon hispanicum. The work aimed to determine the antioxidant activity, phenol and flavonoid contents of their aqueous and methanolic extracts. Flavonoids and phenol contents varied according to the nature of the extract...

Genetic diversity and gene flow revealed by microsatellite DNA markers in some accessions of African Plum (Dacryodes edulis) in Cameroon
Dacryodes edulis is a multipurpose tree integrated in the cropping system of Central African region still dominated by subsistence agriculture. Some populations grown are wild which can provide information on the domestication process, and could also represent a potential source of gene flow. Leaves samples for DNA extraction were collected from wild forms in Mbakwa supe region and from cultivated forms in Yaounde and...

Estimate of genetic diversity in cassutinga (Croton heliotropiifolius) based on molecular markers
The Croton heliotropiifolius (Euphorbiaceae family) is a shrubby plant that has attracted attention both by the need for conservation as for their pharmacological potential. The present study aimed to characterize the diversity and structure genetic of a population of C. heliotropiifolius present in a forest fragment in the city of Itapetinga, Bahia. Young leaves were collected from 41 individuals after DNA extraction...
