Near-Infrared Spectroscopy and Wet Chemistry Dataset for Forage Nutritional Quality Assessment in <i>Urochloa humidicola</i>. [PDF]

Data Brief
Assessing the nutritional quality traits of pastures is crucial for germplasm and breeding evaluations, enabling the selection of high-quality forages to enhance livestock productivity. However, traditional laboratory analytical methods are logistically demanding and costly, particularly in large-scale trials, underscoring the need for rapid, precise ...

A haplotype-complete chromosome-level assembly of octoploid Urochloa humidicola cv. Tully reveals multiple genomic compositions and evolutionary histories in the species. [PDF]

G3 (Bethesda)
Abstract We developed a haplotype-resolved, chromosome-scale genome assembly of the Urochloa humidicola (Rendle) Morrone & Zuloaga cultivar Tully, an apomictic C4 forage grass cultivated in the tropics worldwide. We assembled a 4.1 Gb genome into 48 chromosomes (2n = 8× = 48), capturing 99.5% of the BUSCO markers and annotating ...

Desempeño de dos accesiones de Urochloa humidicola manejadas bajo pastoreo rotacional en el Nordeste Antioqueño (Colombia)

Tropical Grasslands-Forrajes Tropicales
La actividad ganadera en el neotrópico se desarrolla mayormente en suelos ácidos y de baja fertilidad, y la Urochloa humidicola es una alternativa de pasto tropical perenne para esas condiciones.

Use of remote sensors to determine forage availability in grazed pastures of Urochloa humidicola cv. Llanero in the Colombian Altillanura

Tropical Grasslands-Forrajes Tropicales, 2021
Modernization of pastoral systems based on the use of Urochloa species in the Colombian Eastern Llanos need the use of remote sensing techniques from satellite platforms to estimate amount of offered forage.

Role of priority effects in invasive plant species management: Early arrival of native seeds guarantees the containment of invasion by Giant ragweed

Ecology and Evolution, Volume 13, Issue 3, March 2023., 2023
Depending on the sowing times of native and invasive plant species, three priority treatments were conducted: all species sown at the same time (T1); native species sown 3 weeks before Ambrosia trifida (T2); and native species sown 6 weeks before A. trifida (T3). Priority treatments significantly affected the average response of A.

Leaf transcriptome of two highly divergent genotypes of Urochloa humidicola (Poaceae), a tropical polyploid forage grass adapted to acidic soils and temporary flooding areas. [PDF]

BMC Genomics, 2016
Urochloa humidicola (Koronivia grass) is a polyploid (6x to 9x) species that is used as forage in the tropics. Facultative apospory apomixis is present in most of the genotypes of this species, although one individual has been described as sexual. Molecular studies have been restricted to molecular marker approaches for genetic diversity estimations ...

Growth of the invasive Navua sedge (Cyperus aromaticus) under competitive interaction with pasture species and simulated grazing conditions: Implication for management

Ecological Research, Volume 38, Issue 2, Page 331-346, March 2023., 2023
Navua sedge (Cyperus aromaticus) is a major weed in pastures and cropping areas in the wet tropical regions of Australia and South Pacific countries. Understanding the interspecific competitive ability of Navua sedge with co‐occurring desirable grasses is critical for its management in pasture situations.

Abandoned pastures and restored savannas have distinct patterns of plant–soil feedback and nutrient cycling compared with native Brazilian savannas

Journal of Applied Ecology, Volume 59, Issue 7, Page 1863-1873, July 2022., 2022
Despite reducing the resprouting and germination of exotic grasses and improving the establishment of native grasses in the short term, restoration practices have major impacts on the soil microbial community and soil fertility. The reduction of soil microbial biomass and organic matter content reduces the immobilization of soil nutrients and is ...

Molecular dating of phylogenetic divergence between Urochloa species based on complete chloroplast genomes

BMC Genomics, 2017
Background Forage species of Urochloa are planted in millions of hectares of tropical and subtropical pastures in South America. Most of the planted area is covered with four species (U. ruziziensis, U. brizantha, U. decumbens and U.
