Summary: This study reveals the important role of circRNAs in regulating gene expression in plants, with a focus on poplars. CircRNAs in poplars are derived from exon regions and expressed in specific tissues/species. They may finely regulate gene expression in woody plants and play a role in salt tolerance in different poplar species.

Summary: The Brassica species are negatively affected by salt stress, which disrupts their growth and development. However, they exhibit tolerance mechanisms such as organic and inorganic osmolyte accumulation and efficient ion exclusion, with recent studies highlighting the role of ROS in enhancing salt stress tolerance.

Summary: Through comparative transcriptome analysis, we identified the divergence of conserved long noncoding RNAs (lncRNAs) in closely related poplar species with different salt tolerance. Among the identified 34,363 lncRNAs, around 3% were shared with conserved sequences but diversified in their function, copy number, originating genomic region, and expression patterns. Further analysis showed that the conserved lncRNAs displayed more similar expression patterns within salt-tolerant poplars than between salt-tolerant and salt-sensitive poplars. Specifically, the antisense lncRNA lncERF024 was induced by salt and exhibited differentiated expression between salt-tolerant and salt-sensitive poplars. Overexpression of lncERF024 enhanced poplar tolerance to salt stress.

Summary: Nine inositol transporter genes were found in Populus trichocarpa, playing crucial roles in plant growth, development, and stress resistance. Tandem and whole-genome duplication events contributed to the expansion of the PtINT gene family. PtINT1b, a vacuolar inositol transporter, was identified as a candidate gene for enhancing salinity tolerance in plants.

Summary: Saline-alkali soils pose a serious threat to plant growth and productivity worldwide. Scientists have made significant progress in understanding how plants adapt to salt stress by regulating ion homeostasis. The primary goals of plant salt stress signaling research in recent decades have been to understand the molecular mechanisms affecting salt tolerance and develop strategies to breed salt-resistant crops. This review focuses on recent advances in our understanding of the cellular and physiological mechanisms involved in plant responses to salt stress, particularly the changes in signal perception, decoding, and transduction in specific organelles or cells.

Summary: In this study, a salt-inducible NAC gene PsnNAC090 was successfully isolated and found to play an important role in plant development and stress response. Transient transformation experiments confirmed the protein localization in the cell membrane, cytoplasm, and nucleus. Further experiments revealed that PsnNAC090 enhances salt and osmotic tolerance by increasing reactive oxygen species scavenging and reducing lipid peroxide content. These findings suggest that PsnNAC090 is a potential candidate gene for stress response.

Summary: The Brassica genus consists of various cultivated species with economic importance, facing salt stress as a significant problem causing losses in growth and yield. Different species exhibit varying levels of salt tolerance mechanisms, such as the role of neurotransmitters and ion channel regulation. Agronomic strategies have also been discussed to alleviate salt stress severity in Brassica species.

Summary: This study found that PtrDHN-3 gene plays an important role in salt resistance in plants. The expression of PtrDHN-3 protein was induced by salt stress, and transgenic yeast and Arabidopsis plants with PtrDHN-3 overexpression showed increased salt tolerance. The expression levels and activity of antioxidant enzymes were also increased, resulting in decreased accumulation of reactive oxygen species. Additionally, the proline content increased significantly in the overexpressing plants.

Summary: The experiments demonstrated that deep-rooted poplar plants are capable of redistributing water to benefit water stressed neighboring plants in agroforestry systems. This finding provides evidence for an enhanced soil water supply to shallow-rooted crops during drought conditions in agroforest systems.

Summary: Salt stress significantly decreases yield and quality in wheat. This study investigated the physiological, antioxidant enzyme, and transcriptomic responses and mechanisms of salt-tolerant Tritipyrum (Y1805) and salt-sensitive wheat Chinese Spring (CS) to salt stress and recovery. Y1805 exhibited stronger salt tolerance, higher activities of superoxide dismutase and catalase, and higher synthesis of proline and soluble sugars compared to CS under salt stress. Transcriptome analysis revealed differences in the transcriptional regulatory networks of Y1805 not only in response to salt stress, but also during recovery.

Summary: The gene ATL12 plays an important role in the response to salt stress and abscisic acid (ABA) in Arabidopsis thaliana. Overexpression of ATL12 increases the expression of salt stress-associated genes and ABA-responsive genes, and leads to higher levels of reactive oxygen species. Mutants of atl12 are sensitive to salt stress and ABA, and have shorter root length. The findings suggest that ATL12 modulates the response to salt stress and is involved in the ABA signaling pathway.

Summary: This study used poplar doubled haploid plants as experimental material to explore phenotypic differences between homozygous DH plants and paternal plants, and the molecular regulation mechanism behind these differences. Through observation and statistics, it was found that the DH plants had reduced height and diameter, increased leaf aspect ratio, premature senescence of top bud, and significant changes in the shape and cell area of shoot apical meristem. Differentially expressed genes were obtained through RNA-seq transcriptome sequencing, and various physiological processes such as response to oxidative stress, salicylic acid, plant pathogen interaction, and plant hormone signal transduction were found to be involved. A gene regulatory network for phytohormone synthesis and plant senescence was constructed. This study enhances understanding of poplar growth and development regulation and provides new research ideas for the creation of new poplar species.
