Editing Transcriptome (section)

===Plants===
Transcriptome analysis have been used to study the [[evolution]] and diversification process of plant species. In 2014, the [[1000 Plant Genomes Project]] was completed in which the transcriptomes of 1,124 plant species from the families [[viridiplantae]], [[glaucophyta]] and [[rhodophyta]] were sequenced. The protein coding sequences were subsequently compared to infer phylogenetic relationships between plants and to characterize the time of their [[Genetic divergence|diversification]] in the process of evolution.<ref>{{cite journal|title=One thousand plant transcriptomes and the phylogenomics of green plants|date=23 October 2019|volume=574|pages=679–685|author=One Thousand Plant Transcriptomes Initiative|author-link=1000 Plant Genomes Project|journal=Nature|issue=7780|pmid=31645766|pmc=6872490|doi=10.1038/s41586-019-1693-2}}</ref> Transcriptome studies have been used to characterize and quantify gene expression in mature [[pollen]]. Genes involved in cell wall metabolism and cytoskeleton were found to be overexpressed. Transcriptome approaches also allowed to track changes in gene expression through different developmental stages of pollen, ranging from microspore to mature pollen grains; additionally such stages could be compared across species of different plants including ''[[Arabidopsis]]'', [[rice]] and [[tobacco]].<ref>{{cite journal|title=A decade of pollen transcriptomics|first1=Nicholas|last1=Rutley|first2=David|last2=Twell|journal=Plant Reproduction|volume=28|issue=2|pages=73–89|date=12 March 2015|doi=10.1007/s00497-015-0261-7|pmid = 25761645|pmc = 4432081|doi-access=free}}</ref>
