Economic values for traits in breeding objectives for sheep in the tropics: Impact of tangible and intangible benefits por Kosgey, I.S., Arendonk, Johan A.M. van, Baker, R.L.

“…The economic values indicate that litter size, lambing frequency and 12-month lamb live weight are likely to be important traits in pastoral production. Sensitivity analysis showed that future economic values for all the traits considered, except kg manure dry matter sold ewe-1 year-1, might change depending on levels of intangible benefit factors. …”

Recent progress in cassava varietal improvement in the Philippines por Mariscal, Algerico M., Bergantin, Reynaldo V.

“…The continuous introduction of improved cassava populations from the Thai-CIAT program and from CIAT/Colombia contributed to the identification of good varieties, and, consequently, the establishment of cassava genepools having a wide genetic base. This has led to the establishment of a breeding program using the best parents of local and foreign sources. …”

Citrus tristeza virus : a pathogen that changed the course of the citrus industry por Moreno, Pedro, Ambrós, Silvia, Albiach-Martí, María R., Guerri, José, Pena, Leandro

“…The remaining ORFs, expressed via 3'-coterminal subgenomic RNAs, encode proteins required for virion assembly and movement (p6, p65, p61, p27 and p25), asymmetrical accumulation of positive and negative strands during RNA replication (p23), or suppression of post-transcriptional gene silencing (p25, p20 and p23), with the role of proteins p33, p18 and p13 as yet unknown. Analysis of genetic variation in CTV isolates revealed (1) conservation of genomes in distant geographical regions, with a limited repertoire of genotypes, (2) uneven distribution of variation along the gRNA, (3) frequent recombination events and (4) different selection pressures shaping CTV populations. …”
