“…We also analyzed the differences in the cis -element of WOX11/12 genes between easy-to-root trees and difficult-to-root trees. Compared with OsWOX11, OsWOX12a, OsWOX12b, AtWOX11, AtWOX12, PtrWOX11/12a, and PtrWOX11/12b, the promoter of JrWOX11 in “ZNS” walnut and J. regia ( Chang et al, 2020 ) harbored more AuxRE and ABREs but fewer MBS, G-box, W-box, and DRE motifs ( Figure 2 and Supplementary Figure 4 ), which are generally known as elements that respond to abiotic stresses ( Shi et al, 2011 ; Lee et al, 2013 ; Baruah et al, 2021 ). The result might imply that JrWOX11 enhanced the stress tolerance of transgenic “84K” poplar via the ABA-dependent pathways ( Putterill et al, 2021 ).…”

The well-developed root system enables plant survival under various environmental stresses. WUSCHEL-RELATED HOMEOBOX GENE 11 (WOX11) plays a critical role in adventitious root formation and development in rice, Arabidopsis, and easy-to-root tree poplar. However, in difficult-to-root trees, the knowledge of WOX11 during adventitious root formation and development remains scarce. In this study, the JrWOX11 gene was isolated from a difficult-to-root tree walnut and heterologously expressed in the “84K” poplar. The results showed that JrWOX11 contained a similar structure and sequence to the homologous genes in rice, Arabidopsis, and poplar, but had different numbers and types of motifs and cis-elements. JrWOX11 lacked the motif GGAIQY compared to that in easy-to-root trees. In addition, JrWOX11 expression was induced by ABA, PEG, and NaCl treatments. Overexpression of JrWOX11 in poplar promoted root initiation and significantly increased adventitious root (ARs) number, lateral roots (LRs) number, and root hair (RH) length. Furthermore, the aboveground biomass was notably increased under NaCl and PEG treatments in transgenic plants. When NaCl and PEG were removed, the survival rate, aerial shoot development, and de novo root organogenesis were also markedly enhanced in transgenic shoot cuttings. The study provides valuable information on the differences between JrWOX11 and the homologous genes in rice, Arabidopsis, and poplar, and supports the critical role of JrWOX11 in the formation of AR and tolerance to salt and osmotic stresses.

“…This GAMYB-like transcription factor plays a key role in drought alleviation; however, its expression is negatively regulated by miR159 and miR828. During drought stress, these lncRNAs acting as target mimics for both of these miRNAs are expressed and regulate their expression by miRNA sponging to allow the expression of GAMYB for drought stress resilience (Baruah et al, 2021).…”

“…Analysis results showed that the initial target genes of these miRNAs were involved in pathways such as the citrate cycle, purine and thiamine metabolism, and the biosynthesis of unsaturated fatty acids. Exactly how lncRNAs perform their hypothesized function was not determined (Baruah et al 2021 ).…”

The plant genome exhibits a significant amount of transcriptional activity, with most of the resulting transcripts lacking protein-coding potential. Non-coding RNAs play a pivotal role in the development and regulatory processes in plants. Long non-coding RNAs (lncRNAs), which exceed 200 nucleotides, may play a significant role in enhancing plant resilience to various abiotic stresses, such as excessive heat, drought, cold, and salinity. In addition, the exogenous application of chemicals, such as abscisic acid and salicylic acid, can augment plant defense responses against abiotic stress. While how lncRNAs play a role in abiotic stress tolerance is relatively well-studied in model plants, this review provides a comprehensive overview of the current understanding of this function in horticultural crop plants. It also delves into the potential role of lncRNAs in chemical priming of plants in order to acquire abiotic stress tolerance, although many limitations exist in proving lncRNA functionality under such conditions.
