“…Of the above-mentioned Medicago species, purpleflowered alfalfa is the most productive perennial legume with high biomass productivity, an excellent nutritional profile, and adequate persistence [16,17]. Yellow lucerne, which has yellow flowers, is closely related to alfalfa and exhibits better cold tolerance than alfalfa [18,19]. Furthermore, the wild plants of M. varia with multiple flower color variations possess potential resistance to biotic and abiotic stressors [20].…”

Background: To understand the gene expression networks controlling flower color formation in alfalfa, flowers anthocyanins were identified using two materials with contrasting flower colors, namely Defu and Zhongtian No. 3, and transcriptome analyses of PacBio full-length sequencing combined with RNA sequencing were performed, across four flower developmental stages. Results: Malvidin and petunidin glycoside derivatives were the major anthocyanins in the flowers of Defu, which were lacking in the flowers of Zhongtian No. 3. The two transcriptomic datasets provided a comprehensive and systems-level view on the dynamic gene expression networks underpinning alfalfa flower color formation. By weighted gene coexpression network analyses, we identified candidate genes and hub genes from the modules closely related to floral developmental stages. PAL, 4CL, CHS, CHR, F3'H, DFR, and UFGT were enriched in the important modules. Additionally, PAL6, PAL9, 4CL18, CHS2, 4 and 8 were identified as hub genes. Thus, a hypothesis explaining the lack of purple color in the flower of Zhongtian No. 3 was proposed. Conclusions: These analyses identified a large number of potential key regulators controlling flower color pigmentation, thereby providing new insights into the molecular networks underlying alfalfa flower development.

“…Triamine spermidine (Spd), tetraamine spermine (Spm), and their diamine obligate precursor putrescine (Put) are three major PAs in plants, each of which play essential roles in important physiological and developmental processes such as organogenesis, embryogenesis, cell division, floral development, leaf senescence, and fruit maturation processes (Chen, Shao, Yin, Younis, & Zheng, 2018; Seifi & Shelp, 2019). In addition, PAs also have different functions in responses to various biotic and abiotic stresses, such as salt, cold, drought, heavy metal, and high temperature stresses (Chen et al, 2018; López‐Gómez et al, 2017; Soudek, Ursu, Petrova, & Vanek, 2016; Tanou et al, 2014; Wu, Fu, Sun, Xiao, & Liu, 2016; Zhuo, Liang, Zhao, Guo, & Lu, 2018). PAs exhibit essential roles in balance of cellular ROS levels (Gupta, Sengupta, Chakraborty, & Gupta, 2016; Miller, Suzuki, Ciftci‐Yilmaz, & Mittler, 2010).…”

Brassinosteroids (BRs) are known to improve salt tolerance of plants, but not in all situations. Here, we show that a certain concentration of 24-epibrassinolide (EBL), an active BR, can promote the tolerance of canola under high-salt stress, but the same concentration is disadvantageous under low-salt stress. We define this phenomenon as hormonal stress-level-dependent biphasic (SLDB) effects. The SLDB effects of EBL on salt tolerance in canola are closely related to H 2 O 2 accumulation, which is regulated by polyamine metabolism, especially putrescine (Put) oxidation. The inhibition of EBL on canola under low-salt stress can be ameliorated by repressing Put biosynthesis or diamine oxidase activity to reduce H 2 O 2 production. Genetic and phenotypic results of bri1-9, bak1, bes1-D, and bzr1-1D mutants and overexpression lines of BRI1 and BAK1 in Arabidopsis indicate that a proper enhancement of BR signaling benefits plants in countering salt stress, whereas excessive enhancement is just as harmful as a deficiency. These results highlight the involvement of crosstalk between BR signaling and Put metabolism in H 2 O 2 accumulation, which underlies the dual role of BR in plant salt tolerance.
