The phrase "a source of gene" is not correct in written English.
It should be "a source of genes" if referring to multiple genes or "a source of genetic material" for clarity.
Example: "The laboratory is known as a source of genes that contribute to disease resistance in plants."
Alternatives: "a source of genetic information" or "a source of genetic material."
Expressed sequence tags (ESTs) are a source of gene expression information, and are typically inclusive of mitochondrial-derived transcripts.
We use the Molecular Signatures Database (MSigDB) [ 3] as a source of gene pathways.
While one group reported success using exfoliated oral cells as a source of gene expression biomarkers [ 2], others have not obtained satisfactory results [ 3].
Representatives of these families can be recognized by homology-based genomic searches, thus providing a source of gene candidates for pathway reconstruction.
Although we propose that gene duplication associated to structural variations such as CNVs may be an important factor explaining this trend, retropositions have also been shown to be a source of gene duplicates (Kaessmann, 2010).
Gene copy-number differences among individuals and populations can provide a source of gene expression variation (Stranger et al. 2007), although evidence suggests complex relationships between gene copy number and expression (Birchler et al. 2005, 2007).
Because they are frequently large enough to contain an entire gene and its associated regulatory elements, BACs can serve as a source of gene-specific promoter sequences.
Vasemägi, A., Nilsson, J. & Primmer, C. R. Expressed sequence tag-linked microsatellites as a source of gene-associated polymorphisms for detecting signatures of divergent selection in Atlantic salmon (Salmo salar L).
In recent years, aus germplasm has grown in importance as a source of genes for rice improvement, especially in the context of breeding for resistance/tolerance to abiotic and biotic stress (Travis et al. 2015 and references therein).
We use them as a source of genes and, in these extremely dry habitats, like Ascension, plants that are naturally adapted may hold some answers to things like plants' responses to climate change".
Also the non STGs including the cereal crops are also the source of salt tolerant genes, but the prime focus of this review will be on the STGs to understand their salt tolerance mechanism and assess their potentiality as a source of genes for improving the salt tolerance of cereal crops.
