Genomic homeology between Pennisetum purpureum and Pennisetum glaucum (Poaceae)

The genus Pennisetum (Richard, 1805) includes two economically important tropical forage plants: Pennisetum purpureum (Schumacher, 1827) (elephant grass), with 2n = 4x = 28 chromosomes and genomes A'A'BB, and Pennisetum glaucum (Linnaeus, 1753) (pearl millet), with 2n = 2x = 14 chromosomes and genomes AA. The genetic proximity between them allows hybrids to be obtained (2n = 3x = 21) that yield...

Diversity among isolates of cowpea severe mosaic virus infecting cowpeas in northeastern Brazil.

Eleven isolates of cowpea severe mosaic virus (CPSMV), a member of the genus Comovirus, were selected from 50 samples collected of nine cowpea fields in Northeastern Brazil (Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Sergipe, Bahia, and Distrito Federal) and partially sequenced. The RNA1 partial sequence, corresponding to the helicase, viral genome-linked protein, pic...

DNA elimination in embryogenic development of Pennisetum glaucum x Pennisetum purpureum (Poaceae) hybrids.

Interspecific hybridization between Napier grass (Pennisetum purpureum), which is widely grown in Brazil for cattle forage, and pearl millet (Pennisetum glaucum) has been used as a breeding strategy for the development of improved cultivars. However, the hybrid between these two species is sterile due to its triploid condition (2n = 3x = 21 chromosomes), which hinders its use in crop breeding p...
