The biological significance of non-coding RNAs (ncRNAs) has been firmly established to be important for the regulation of genes involved in stress acclimation. Light plays an important role for the growth of plants providing the energy for photosynthesis; however, excessive light conditions can also cause substantial defects. Small RNAs (sRNAs) are a class of non-coding RNAs that regulate transcript levels of protein-coding genes and mediate epigenetic silencing.

Besides transcriptional control of gene expression, different classes of small non-coding RNAs (sRNAs) act in gene expression control, but comprehensive analyses regarding their role in retrograde signalling are lacking. We performed sRNA profiling in response to norflurazon (NF), which provokes retrograde signals, in Arabidopsis thaliana wild type (WT) and the two retrograde signalling mutants gun1 and gun5.

- Cold stress influences gene expression changes in plants, primarily through small non-coding RNAs (sRNAs) like microRNAs (miRNAs) and small interfering RNAs (siRNAs), which are essential for understanding cold-related adaptations.
- Researchers exposed Arabidopsis thaliana to cold conditions (4°C) and discovered 93 miRNAs responsive to cold, only 14 of which were previously known to be affected by cold.
- The study successfully mapped a gene regulatory network influenced by miRNAs and transcription factors, highlighting the critical role of various sRNAs in managing gene expression during cold acclimation, contributing to a comprehensive understanding of these regulatory processes.
