“…Additionally, a striking uniformity in the number and arrangement of exons/introns was observed within subfamily members. Notably, prior research has documented a range of 0 to 10 exons/introns in sesame bHLH genes ( Kazemitabar, Faraji & Najafi-Zarrini, 2020 ). Similarly, Andrographis paniculata presents a variation of 0 to 14 exons/introns ( Xu et al, 2022 ), and P. canescens exhibits a similar range from 0 to 14.…”

The basic helix-loop-helix (bHLH) gene family is integral to various aspects of plant development and the orchestration of stress response. This study focuses on the bHLH genes within Populus × canescens, a poplar species noted for its significant tolerance to cadmium (Cd) stress. Through our comprehensive genomic analysis, we have identified and characterized 170 bHLH genes within the P. canescens genome. These genes have been systematically classified into 22 distant subfamilies based on their evolutionary relationships. A notable conservation in gene structure and motif compositions were conserved across these subfamilies. Further analysis of the promoter regions of these genes revealed an abundance of essential cis-acting element, which are associated with plant hormonal regulation, development processes, and stress response pathway. Utilizing quantitative PCR (qPCR), we have documented the differential regulation of PcbHLHs in response to elevated Cd concentrations, with distinct expression patterns observed across various tissues. This study is poised to unravel the molecular mechanism underpinning Cd tolerance in P. canescens, offering valuable insights for the development of new cultivars with enhanced Cd accumulation capacity and tolerance. Such advancements are crucial for implementing effective phytoremediation strategies to mitigate soil pollution caused by Cd.

Quercus mongolica is a tall tree with a broad, rounded crown and lush leaves. In autumn, the leaves turn red and have great ornamental value. However, the molecular mechanisms that cause the change in leaf colour are unknown. In this study, we identified 12 differentially expressed genes involved in anthocyanin synthesis by analysing the transcriptome of Q. mongolica leaves in six developmental stages (S1 − S6). We further analysed the dynamics of anthocyanin content in Q. mongolica leaves in four developmental stages (S1, S2, S5, and S6) using differential gene expression patterns. We detected a total of 48 anthocyanins and categorised these into seven major anthocyanin ligands. The most abundant anthocyanins in the red leaves of Q. mongolica were cyanidin-3,5-O-diglucoside, cyanidin-3-O-glucoside, cyanidin-3-O-sophoroside, and pelargonidin-3-O-glucoside. Correlation analysis of differentially expressed genes and anthocyanin content identified highly expressed QmANS as a key structural gene associated with anthocyanin biosynthesis in Q. mongolica. A transcription factor-structural gene correlation analysis showed that the 1bHLH, 3bZIP, 1MYB, 10NAC, and 2WRKY transcription factors played strong positive roles in regulating anthocyanin structural genes (|PCC| > 0.90), with the QmNAC transcription factor playing a major role in anthocyanin biosynthesis.
