e-infrastructure Roadmap for Open Science in Agriculture

A bibliometric study

The e-ROSA project seeks to build a shared vision of a future sustainable e-infrastructure for research and education in agriculture in order to promote Open Science in this field and as such contribute to addressing related societal challenges. In order to achieve this goal, e-ROSA’s first objective is to bring together the relevant scientific communities and stakeholders and engage them in the process of coelaboration of an ambitious, practical roadmap that provides the basis for the design and implementation of such an e-infrastructure in the years to come.

This website highlights the results of a bibliometric analysis conducted at a global scale in order to identify key scientists and associated research performing organisations (e.g. public research institutes, universities, Research & Development departments of private companies) that work in the field of agricultural data sources and services.

Membrane Proteins Associated with Sperm-Oocyte Interaction: A Proteomic Comparison between Kedah Kelantan (Bos indicus) and Mafriwal (Bos taurus x Bos indicus) Sperm


Production performance of European cattle breeds has significantly improved through various breeding programs. However, European breeds are more susceptible to heat stress compared to zebu cattle (Bos indicus) as their conception rate can range between 20 to 30% in hot seasons compared to winter. To identify cattle sperm proteins associated with zebu cattle higher fertility and heat tolerance in tropical environments, we utilised a proteomics-based approach to compare sperm from the highly fertile Malaysian indigenous breed, Kedah Kelantan (Bos indicus), with sperm from the sub-fertile crossbreed, Mafriwal (Bos taurus x Bos indicus). Frozen semen of three high performance bulls from each breed was processed to obtain live and pure sperm. Proteins were separated and gel bands were processed by in-gel tryptic digestion. For each breed, mass spectrometry data was acquired over 11 replicates. The analyzed data identified peptides with different expression levels (99% confidence level) and protein identification was determined by targeted MS/MS. Among the identified proteins associated with sperm-oocyte interaction, two proteins were up-regulated in Kedah Kelantan sperm and 7 proteins were up-regulated in or specific to Mafriwal. Our results suggest that the higher fertility of zebu cattle in tropical areas may not be related to more efficient sperm-oocyte interaction. Further analysis of the other regulated proteins in these two breeds may contribute further knowledge on the physiological reason/s for higher fertility and heat tolerance of Zebu cattle in tropical areas.
