Transgenic Food

Agrobacterium rhizogenesandAgrobacterium tumefaciensare plant pathogenic bacteria capable of transferring DNA fragments [transfer DNA (T-DNA)] bearing functional genes into the host plant genome. This naturally occurring mechanism has been adapted by plant biotechnologists to develop genetically modified crops that today are grown on more than 10% of the world’s arable land, although their use can result in considerable controversy. While assembling small interfering RNAs, or siRNAs, of sweet potato plants for metagenomic analysis, sequences homologous to T-DNA sequences fromAgrobacteriumspp. were discovered. Simple and quantitative PCR, Southern blotting, genome walking, and bacterial artificial chromosome library screening and sequencing unambiguously demonstrated that two different T-DNA regions (IbT-DNA1 andIbT-DNA2) are present in the cultivated sweet potato (Ipomoea batatas[L.] Lam.) genome and that these foreign genes are expressed at detectable levels in different tissues of the sweet potato plant.IbT-DNA1 was found to contain four open reading frames (ORFs) homologous to the tryptophan-2-monooxygenase (iaaM), indole-3-acetamide hydrolase (iaaH), C-protein (C-prot), and agrocinopine synthase (Acs) genes ofAgrobacteriumspp.IbT-DNA1 was detected in all 291 cultigens examined, but not in close wild relatives.IbT-DNA2 contained at least five ORFs with significant homology to theORF14,ORF17n, rooting locus (Rol)B/RolC,ORF13, andORF18/ORF17ngenes ofA. rhizogenes.IbT-DNA2 was detected in 45 of 217 genotypes that included both cultivated and wild species. Our finding, that sweet potato is naturally transgenic while being a widely and traditionally consumed food crop, could affect the current consumer distrust of the safety of transgenic food crops.

The reinvestment of rural agrarian surplus is driving capital accumulation in Zimbabwe's countryside, providing a scope to foster national (re-) industrialisation and job creation. Contrary to Bernstein's view, the Agrarian Question on capital remains unresolved in Southern Africa. Even though export finance, accessed through contract farming, provides an impetus for export cash crop production, and the government-mediated command agriculture supports food crop production, the reinvestment of proceeds from the sale of agricultural commodities is now driving capital accumulation. Drawing from empirical data, gathered through surveys and in-depth interviews from Hwedza district and Mvurwi farming area in Mazowe district in Zimbabwe, the findings of this study revealed the pre-eminence of the Agrarian Question, linked to an ongoing agrarian transition in Zimbabwe. This agrarian capital elaborates rural-urban interconnections and economic development, following two decades of de-industrialisation in Zimbabwe.

<em>Sweet potato is an important staple food crop especially for the local people of Central Highlands Jayawijaya. There are many accessions that have always been maintained its existence to enrich their various uses. Traditionally, sweet potato accessions were grouped based on the utilization, such as for animal feed, cultural ceremonies, consumption for adults, as well as for infants and children. This study was aimed to analyze the nutritional value of sweet potatoes consumed by infants and children of the Dani tribe. Chemical analyses were conducted at the Laboratory of Post-Harvest Research and Development Center, Cimanggu, Bogor. The results showed that each of 4 (four) sweet potato accessions which were consumed by infants and children had good nutrient levels. Accession Sabe showed the highest water content (72.56%), vitamin C (72.71 mg/100 g), Fe (11.85 mg/100 g), and K levels (130.41 mg / 100 grams). The highest levels of protein (1.44%), fat (1.00%), energy (154.43 kkal/100 gram), carbohydrate (35.47%), starch (30.26%), reducing sugar (3.44%), riboflavin (0.18 mg/100 g), and vitamin A (574.40 grams IU/100 were produced by accession Manis. On the other hand, accession Saborok produced the highest value for ash content (1.32%), vitamin E (28.30 mg/100 g), and ?-carotene (64.69 ppm). The highest level of crude fiber (1.81 %) and thiamin (0.36 mg/100 g) was produced by accession Yuaiken.</em>

Intention of� this research� is to determine of� agriculture prime commodities of South Buru Regency. The observation was focussed to know potensial area to development agriculture harvesting/cattle.� This paper aims to examine the implementation of LQ approach uses wide of �agriculture harvesting/cattle population series data for five year period (2005-2009) from South Buru Regency as main source. The result of study showed that there was most of sub regency in South Buru regency have the same of prime commodities, and several sub regency have specific prime commodities. The number of prime commodities to the sub sector food crop agriculture are 6, prime commodities to sub sector vegetables and fruits planting are 18, prime commodities to the sub sector tree crop planting are 5� and prime commodities to sub sector husbandry /breeding are 5 commodities.
