Transcriptome profiling uncovers the lncRNA-mediated regulatory networks associated with tolerance to cadmium stress in barley

Underground communication: Long non-coding RNA signaling in the plant rhizosphere

“…Transcriptomic analysis in barley identified 9937 novel lncRNAs, including predicted cis -regulatory and trans -acting pairs ( Zhou et al., 2023 ). A comparison of Cd-tolerant and Cd-sensitive lines revealed 195 differentially expressed lncRNAs, including eight that functioned as miRNA target mimics.…”

“…In addition, the lncRNAs LTCONS_00032998 , LTCONS_00061453 , and LTCONS_00114133 maintained cell-wall integrity by targeting the cell-wall-associated genes FLA , POD , and SNARE1 , respectively. LTCONS_00157527 targeted HPR1 , a gene involved in mRNA export, suggesting a role in facilitating Cd tolerance ( Figure 4 ) ( Zhou et al., 2023 ). Similarly, 301 lncRNAs responsive to Cd were found in rapeseed, 67 of which acted as endogenous miRNA target mimics.…”

“…As a consequence, ROS play a key role in the development of defense systems, thereby increasing plant tolerance to harsh environments. A recent study revealed that lncRNAs regulate the expression of adjacent genes located close together in the genome ( Zhou et al., 2023 ), thereby regulating plant responses to rhizosphere signals.…”
