Phenotypic variation in milk fatty acid composition and its association with stearoyl‐CoA desaturase 1 (SCD1) gene polymorphisms in Gir cows

Journal of Animal Breeding and Genetics, Volume 140, Issue 5, Page 532-548, September 2023., 2023
Abstract Individual variation in milk fatty acid (FA) composition has been partially attributed to stearoyl‐CoA desaturase 1 (SCD1) gene polymorphisms in taurine breeds, but much less is known for Zebu breeds. This study investigated the phenotypic variation in milk FA composition, and the influence of SCD1 variants on this trait and on milk fat ...

Molecular mechanisms associated with rootstock-scion interactions in rubber trees. [PDF]

Plant Genome
Abstract Hevea brasiliensis (rubber tree) is the main source of natural rubber worldwide. In commercial plantations, high‐yield rubber tree clones are propagated by grafting onto seedling rootstocks. In this study, the transcriptomes of the RRIM 600 clone grafted on different rootstocks in southeastern Brazil were evaluated. Exclusively expressed genes

Agronomic Behaviour and Chemical Composition of Three Varieties of Pennisetum sp in the Peruvian Tropics

International Journal of Agronomy, Volume 2023, Issue 1, 2023., 2023
Livestock production in the Peruvian tropics is mainly based on grazing and cutting grasses, which have variable productive and nutritional characteristics according to the variety of grasses, agronomic management, and climatic conditions. The objective of this research was to compare the agronomic behaviour and chemical composition of three varieties ...

Clonal Propagation of Coffea arabica with Indole Butyric Acid and Acclimatization Conditions in Amazonas, Peru

International Journal of Agronomy, Volume 2021, Issue 1, 2021., 2021
The use of hormones is important in improving the propagation process. The objective of the experiment was to identify the best dose of indole butyric acid (IBA) hormone for the rooting of coffee cuttings of the typical variety through clonal propagation in the Amazon region. The experiment was carried out in two stages.
