摘　　要：Phosphorus(P)is a vital nutrient for plant growth,acquired primarily in the form of inorganic phosphate(Pi).Pi deficiency limits plant growth and development and significantly constrains crop productivity worldwide.To face scarcity and maintain P homeostasis,plants have evolved different strategies to acquire this nutrient efficiently,where the regulation of gene expression plays a pivotal role,and several non-coding RNAs(ncRNAs)were shown to participate in this elaborate regulation.At the transcriptional level,responses to Pi deficiency are highly conserved between Arabidopsis thaliana and rice(Oryza sativa).For example,the MYB transcription factor At-PHR1 in Arabidopsis and its paralogs At-PHL1 and Os-PHR2 in rice play a pivotal role in the Pi starvation signaling pathway(Rubio et al.,2001;Zhou et al.,2008;Bustos et al.,2010;Das et al.,2022).
