Project Title
Functional analysis of long intergenic non-coding RNAs in phosphate-starved rice using competing endogenous RNA network
The Background of This Project
- Long intergenic non-coding RNAs (lincRNAs) may play widespread roles in gene regulation and other biological processes, however, a systematic examination of the functions of lincRNAs in the biological responses of rice to phosphate (Pi) starvation has not been performed. Here, we used a computational method to predict the functions of lincRNAs in Pi-starved rice. Overall, 3,170 lincRNA loci were identified using RNA sequencing data from the roots and shoots of control and Pi-starved rice.
- Inorganic phosphate (Pi) is essential for the growth and productivity of plants; however, those in agricultural environments can be exposed to Pi starvation 1 . Understanding the biological responses of plants to Pi starvation is vital for improving the efficiency of Pi use and maintaining an acceptable yield 2 . A number of studies have attempted to investigate the complex mechanisms regulating Pi homeostasis in rice, and have reported regulation at the transcript level 3–6 . Long integrate non-coding RNAs (lincRNAs) exist in both mammalian and plants and may play widespread roles in gene regulation and other biological processes 7–9 , however, the function of lincRNAs that response to Pi starvation are poorly understood.
- The competing endogenous RNA (ceRNA) theory has been proved and is now acknowledged widely 10,11 . This theory states that ceRNAs, including mRNA, lincRNAs, pseudogenes, and other microRNAs (miRNA) sponges, share common miRNA binding sites and can act as molecular sponges because the amount of a given miRNAs is limited 11 . LincRNAs compete with other miRNA sponges to play important roles in both plants and animals 9,12–15 . In addition, ceRNA networks are useful for studying cancer biology and other biological problems 16–19 . However, to our knowledge, ceRNA networks have not yet been used to study the functions of lincRNAs in plants such as Arabidopsis and rice.
