INTRODUCTION

Awareness of the consequences of exploiting non-renewable resources for fuel production, together with rising petroleum prices and increased emission of greenhouse gases, has stimulated researchers to develop alternative sustainable energy resources, and has boosted the demand for biofuels (Gan and Li, 2013).

Development of novel simple sequence repeat markers from a genomic sequence survey database and their application for diversity assessment in Jatropha curcas germplasm from Guatemala

R. S. Raposo, Souza, I. G. B., Veloso, M. E. C., Kobayashi, A. K., Laviola, B. G., and Diniz, F. M., “Development of novel simple sequence repeat markers from a genomic sequence survey database and their application for diversity assessment in Jatropha curcas germplasm from Guatemala”, vol. 13, pp. 6099-6106, 2014.

The last few years have seen a significant increase in the number of large-scale sequencing projects generating whole genome databases. These sequence databases can be surveyed (genome sequence survey) for tandem repeats as an alternative means to develop microsatellites for monitoring and selecting natural populations and cultivars of Jatropha curcas. A total of 100 tandem repeats were revealed from mining 368 genomic surveyed sequences available in the Kazusa DNA Research Institute database.

Establishment and molecular characterization of a sweet potato germplasm bank of the highlands of Paraná State, Brazil

L. K. P. Camargo, Mógor, A. F., Resende, J. T. V., and Da-Silva, P. R., “Establishment and molecular characterization of a sweet potato germplasm bank of the highlands of Paraná State, Brazil”, vol. 12, pp. 5574-5588, 2013.

The sweet potato (Ipomoea batatas L.) is a crop of great importance in developing countries, as a food staple, for animal feed, and potentially for biofuel. Development of cultivars adapted to specific regions within these countries would be useful. To start a breeding program, the first step is the establishment of a germplasm bank. We initiated a sweet potato germplasm bank with accessions collected from the highlands of Paraná State, Brazil.

Genetic diversity in tetraploid switchgrass revealed by AFLP marker polymorphisms

J. Todd, Wu, Y. Q., Wang, Z., and Samuels, T., “Genetic diversity in tetraploid switchgrass revealed by AFLP marker polymorphisms”, vol. 10, pp. 2976-2986, 2011.

Switchgrass (Panicum virgatum) is a perennial warm-season grass native to North America that has been identified as a dedicated cellulosic biofuel crop. We quantified genetic diversity in tetraploid switchgrass germplasm collected at Oklahoma State University and characterized genetic relatedness among the collections from distinct regions. Fifty-six tetraploid accessions, including seven upland and 49 lowland genotypes from throughout the US, were examined.
