alleles; breeding; center of origin; corn; gene frequency; genetic variation; germplasm; hybrids; inbred lines; linkage disequilibrium; loci; seeds; single nucleotide polymorphism; Brazil; China
Abstract:
... Characterization of genetic diversity is of great value to assist breeders in parental line selection and breeding system design. We screened 770 maize inbred lines with 1,034 single nucleotide polymorphism (SNP) markers and identified 449 high-quality markers with no germplasm-specific biasing effects. Pairwise comparisons across three distinct sets of germplasm, CIMMYT (394), China (282), and Br ...

Subject:
Passiflora; ornamental plants; plant breeding; hybrids; interspecific hybridization; plant genetic resources; floriculture; ornamental value; wild relatives; commercialization; sustainable agriculture; Brazil
Abstract:
... The Passiflora L. (Passifloraceae) genus consists of about 500 species widely distributed throughout tropical and subtropical regions, commonly known as the passion flower. The passion flowers are considered ornamental plants because of the exotic beauty of their flowers and variant foliage. Since their introduction to the Old World, around 1625, seventeenth century, they have been used to decorat ...

Abstract:
... The majority of individuals in the chronic phase of Chagas disease are asymptomatic (indeterminate form, IF). Each year, ~3% of them develop lesions in the heart or gastrointestinal tract. Cardiomyopathy (CCHD) is the most severe manifestation of Chagas disease. The factors that determine the outcome of the infection are unknown, but certainly depend on complex interactions amongst the genetic mak ...

Subject:
sap flow; carbon dioxide; hybrids; soil fertility; Eucalyptus urophylla; Eucalyptus grandis; leaves; forest trees; photorespiration; stand density; branches; tree growth; volume; wood; tree age; geographical variation; nitrogen; Eucalyptus saligna; forest plantations; sapwood; Brazil; Hawaii
Abstract:
... We measured CO2 efflux from wood for Eucalyptus in Hawaii for 7 years and compared these measurements with those on three- and four-and-a-half-year-old Eucalyptus in Brazil. In Hawaii, CO2 efflux from wood per unit biomass declined approximately 10x from age two to age five, twice as much as the decline in tree growth. The CO2 efflux from wood in Brazil was 8–10x lower than that for comparable Haw ...
