What is another word for trans-acting sirna?
Pronunciation: [tɹˈanzˈaktɪŋ sˈɜːnə] (IPA) 
Trans-acting small interfering RNA (tasiRNA) is a type of small RNA molecule that is involved in gene regulation in plants. It is produced from non-coding transcripts that are complementary to specific genes, and can target and silence those genes. TasiRNA has been extensively studied in plants, but its role in other organisms is less clear. Alternative names for trans-acting siRNA include secondary siRNA, endogenous siRNA, and plant-specific siRNA. These terms highlight the fact that tasiRNA is distinct from other types of siRNA, which are usually generated from exogenous sources such as viruses or transgenes. Understanding the role of tasiRNA in gene regulation may have important implications for plant breeding and crop improvement.
