Brachiaria species are some of the most used forage species for raising Brazilian cattle because of their great nutritional value and adaptability to the tropical climate. However, cases of animal intoxication have been described. Animal species, age, genetic resistance, and previous adaptation to the forage can influence the susceptibility to ...

In situ hybridization with mRNA probes enables the detection and localization of gene expression in plant somatic embryogenesis samples. BbrizSERK is a gene that is expressed in embryogenic cells and tissues of Brachiaria. Here we describe methods used for in situ hybridization to localize BbrizSERK transcripts during somatic embryogenesis of ...

Brachiaria, a genus from the Poaceae family, is largely cultivated as forage in Brazil. Among the most cultivated varieties of Brachiaria spp., B. brizantha cv. Marandu (syn. Urochloa brizantha) is of great agronomical importance due to the large areas cultivated with this species. This cultivar is apomictic and tetraploid.

Somatic Embryogenesis and Plant Regeneration of Brachiaria brizantha
2016The genus Brachiaria (Trin.) Griseb. belongs to the family Poaceae, order Poales, class Monocotyledonae. In Brachiaria brizantha (Hochst. ex A. Rich.) Stapf., embryogenic callus can be induced from seeds from apomictic plants, which results in high frequency somatic embryo development and plant regeneration.

Direct evidence of pseudogamy in apomictic Brachiaria brizantha (Poaceae)
Sexual Plant Reproduction, 2001Brachiaria brizantha is a forage grass that has several apomictic accessions. B. brizantha cv. Marandu is a natural tetraploid aposporous apomict widely cultivated in Brazil. Pseudogamy was detected in this species by observation that seed set is suppressed in plants that have had the stigmas excised from the flowers.

The meiotic behavior of two half-sib interspecific tetraploid (2n = 4x = 36) promising hybrids, a sexual and an apomictic one, from crosses B. ruziziensis and B. brizantha, was evaluated. Although chromosome paired predominantly as bivalents, a few tri- and quadrivalents were recorded. Results suggest that B. brizantha and B.

Chromosome numbers and microsporogenesis in Brachiaria brizantha (Gramineae)
Euphytica, 2002The genus Brachiaria, native to the African tropical savannas, has achieved significance as a pasture grass in many tropical and subtropical countries, including Brazil. Many species and accessions are polyploid and apomictic, which complicates the improvement of breeding stocks through hybridization.
