Evidence of Allopolyploidy in Urochloa humidicola Based on Cytological Analysis and Genetic Linkage Mapping
The African species Urochloa humidicola (Rendle) Morrone & Zuloaga (syn. Brachiaria humidicola (Rendle) Schweick.) is an important perennial forage grass found throughout the tropics. This species is polyploid, ranging from tetra to nonaploid, and apomictic, which makes genetic studies challenging; therefore, the number of currently available genetic resources is limited. The genomic architectu...
متن کاملتاثیر بازدارندگی ترشحات رشد brachiaria humidicola نیتریفیکاسیون
ممانعت از نیتریفیکاسیون در اکوسیستمهای طبیعی چندین دهه است که مطرح میباشد. این اثرات ممانعت کنندگی یک ویژگی ژنوتیپهای وحشی میباشد تا ارقام تجاری. بسیاری از گیاهان مخصوصاً گراسها نشان داده شده اند که دارای این خاصیت ممانعت از نیتریفیکاسیون هستند و اخیراً برخی ژنوتیپهای Brachiaria مخصوصاً humidicola Brachiaria توجه زیادی را به سبب نقش آنها در کاهش میزان نیتریفیکاسیون در خاک از طریق ترشحات ریش...
متن کاملSalt stress response and proline accumulation in Brachiaria humidicola plants with and without mycorrhizal inoculation.
The work was carried out to investigate the effects of different concentrations of NaCl on Brachiaria humidicola Rendle in the presence and absence of Glomus etunicatum Becker and Gerdemann, as well as to evaluate some growth parameters and the accumulation of free proline in the plant leaves. The soil used was a Neosoil Fluvic Eutrophic with pH of 6.5, organic matter, 12.8 g kg-1 and soil text...
متن کاملEvaluation of Biological Nitrification Inhibition (BNI) Capacity in a Biparental Mapping Population of Brachiaria humidicola
Soil nitrogen (N) loss due to rapid nitrification (oxidation of ammonium to nitrate) is a serious problem with economic and environmental implications. As a result, a large proportion of N fertilisers applied to crops are lost to the environment via nitrate leaching and nitrous oxide emissions. The tropical pasture grass Brachiaria humidicola (Bh) exudes organic molecules from roots that inhibi...
متن کاملOrigin of a polyploid accession of Brachiaria humidicola (Poaceae: Panicoideae: Paniceae).
Brachiaria humidicola, a species adapted to poorly drained and infertile acid soils, is widely used throughout the tropics. Cytological characterization of 54 accessions of B. humidicola for breeding purposes revealed 2n = 36, 42, and 54 chromosomes. One accession (H030), with 2n = 42 chromosomes, showed a different meiotic behavior. In most accessions from the genus Brachiaria previously studi...
