The phrase "abundant transcripts have" is correct and usable in written English.
It can be used when discussing the availability or quantity of transcripts in a particular context, such as research or documentation.
Example: "In our study, we found that abundant transcripts have been generated, providing a wealth of data for analysis."
Alternatives: "plentiful transcripts possess" or "numerous transcripts contain".
5'UTRs of abundant transcripts have significantly higher GC-content and were enriched three-fold with repetitive GGCGGCGGC motifs (p<5×10−55), complementary CCGCCGCCG motifs (p<9×10−39), and other GC-containing sites, as compared to rare transcripts (Table S1).
A recent global analysis of mRNA stability in M. tuberculosis concluded that more abundant transcripts have shorter half-lives (Rustad et al., 2013).
Of the conifer-specific xylem unigenes several relatively abundant transcripts have low homology to arabinogalactan-like proteins (AGPs), glycine/proline-rich proteins (GPRP), metallothionein-like class II proteins, neurofilament triplet H proteins, zinc finger proteins, cytochrome c1, etc (Additional file 8).
One complication that we faced was that the CV of a transcript level among animals depends on the expression level of a transcript, with more abundant transcripts having less variation – as would be expected, since more abundant transcripts could be measured more reliably than the less abundant ones.
However, it should be highlighted that two of these highly abundant transcripts had no similarity with any available sequence, either in UniProt or NR databases, while two other large clusters represent proteins that might be involved in stress responses (HSP70 and ferritin).
Benefiting from the rapid progress in next-generation sequencing technology, a huge number of these low abundant circRNA transcripts have sprung up in recent years (Jeck et al., 2013; Memczak et al., 2013; Salzman et al., 2013; Salzman et al., 2012; Wang et al., 2014; Zhang et al., 2013).
Our data suggest that 5'UTRs of abundant PK transcripts have significantly higher hybridization affinity to 18S rRNA, than 5'UTRs of rare PK transcripts (Figure 5).
In several other organisms outside the plant kingdom (i.e. yeast, mouse, and humans), large differences between abundant and rare transcripts have also been observed [ 36].
A significant number of the highly abundant barley seed transcripts have no orthologous genes in Arabidopsis; or their orthologs or strong homologs do not highly accumulate in Arabidopsis dry seeds.
The experimental screens for E. coli sRNAs have either been limited to highly abundant transcripts or have specifically targeted transcripts that interact with the RNA chaperone Hfq [40] [43].
The 24-hour post infection period may have been non-optimal for expression of some genes, and since the EST library was not normalized the less abundant transcripts may have gone undetected.
