“…A larger number of genes have been identified to mediate plant stress tolerance and can be used for crop improvement [23,[29][30][31]. Aquaporins play an important role in regulating plant growth because they can, for example, influence root water uptake and leaf gas exchange, as well as other physiological process.…”

Salt tolerance is an important trait in soybean cultivation and breeding. Plant responses to salt stress include physiological and biochemical changes that affect the movement of water across the plasma membrane. Plasma membrane intrinsic proteins (PIPs) localize to the plasma membrane and regulate the water and solutes flow. In this study, quantitative real-time PCR and yeast two-hybridization were engaged to analyze the early gene expression profiles and interactions of a set of soybean PIPs (GmPIPs) in response to salt stress. A total of 20 GmPIPs-encoding genes had varied expression profiles after salt stress. Among them, 13 genes exhibited a downregulated expression pattern, including GmPIP1;6, the constitutive overexpression of which could improve soybean salt tolerance, and its close homologs GmPIP1;7 and 1;5. Three genes showed upregulated patterns, including the GmPIP1;6 close homolog GmPIP1;4, when four genes with earlier increased and then decreased expression patterns. GmPIP1;5 and GmPIP1;6 could both physically interact strongly with GmPIP2;2, GmPIP2;4, GmPIP2;6, GmPIP2;8, GmPIP2;9, GmPIP2;11, and GmPIP2;13. Definite interactions between GmPIP1;6 and GmPIP1;7 were detected and GmPIP2;9 performed homo-interaction. The interactions of GmPIP1;5 with GmPIP2;11 and 2;13, GmPIP1;6 with GmPIP2;9, 2;11 and GmPIP2;13, and GmPIP2;9 with itself were strengthened upon salt stress rather than osmotic stress. Taken together, we inferred that GmPIP1 type and GmPIP2 type could associate with each other to synergistically function in the plant cell; a salt-stress environment could promote part of their interactions. This result provided new clues to further understand the soybean PIP–isoform interactions, which lead to potentially functional homo- and heterotetramers for salt tolerance.

“…Numerous studies have reported the identi cation of functional genes that are relevant to plant stress tolerance and that can be used for crop improvement [18][19][20][21]. To aid efforts to breed salinity tolerance in soybean, we analyzed the orthologs of plasma membrane intrinsic proteins (PIPs) in soybean and tested their interactions using a yeast two-hybrid system.…”

Background: Salt tolerance is a key trait in soybean breeding and plant responses to salt stress include physiological and biochemical changes that affect the movement of water across the plasma membrane. In this study, we report the interactions of a set of aquaporins, soybean (Glycine max) plasma membrane-intrinsic proteins (GmPIPs), in response to salt stress. Results: GmPIP1;5 and GmPIP1;6 formed hetero-tetramers with GmPIP2;4, GmPIP2;6, GmPIP2;8, GmPIP2;9, GmPIP2;11, and GmPIP2;13. We detected interactions between GmPIP1;6 and GmPIP1;7, but not between GmPIP1;6 and GmPIP1;5. Furthermore, GmPIP2;9 formed homo-tetramers, and this interaction was strengthened under salt and osmotic stress. Expression analysis indicated complex and unique responses to salt stress depending on the duration of the stress. For example, GmPIP2;8, encoding one of the heteromer-forming PIP proteins, was highly up-regulated under early salt stress.Conclusions: Our study highlights the vital role of hetero- and homo-tetramers, in salt tolerance; and improves understanding of the mechanisms by which soybean aquaporin isoforms respond to abiotic stress.

Basic helix-loop-helix proteins (bHLHs) comprise one of the largest families of transcription factors in plants. They have been shown to be involved in responses to various abiotic stresses, such as drought, salinity, chilling, heavy metal toxicity, iron deficiency, and osmotic damages. By specifically binding to cis-elements in the promoter region of stress related genes, bHLHs can regulate their transcriptional expression, thereby regulating the plant’s adaptive responses. This review focuses on the structural characteristics of bHLHs, the regulatory mechanism of how bHLHs are involved transcriptional activation, and the mechanism of how bHLHs regulate the transcription of target genes under various stresses. Finally, as increasing research demonstrates that flavonoids are usually induced under fluctuating environments, the latest research progress and future research prospects are described on the mechanisms of how flavonoid biosynthesis is regulated by bHLHs in the regulation of the plant’s responses to abiotic stresses.
