Integrative transcriptomic, metabolomic, and physiological analyses reveal the role of strigolactones in enhancing drought resistance in Juglans sigillata

Plant Physiology and Biochemistry
Juglans sigillata, an economically valuable tree species mainly cultivated in southwest China, is frequently affected by seasonal drought, which significantly impacts its growth and yield. This study investigated the role of strigolactones (SLs) in mitigating drought stress through physiological, transcriptomic, and metabolomic analyses, along with ...

Establishment of virus-induced gene-silencing system in Juglans sigillata Dode and functional analysis of JsFLS2 and JsFLS4

Gene
Juglans sigillata Dode is one of the important tree species in southwest China, and it has significant economic and ecological value. However, there is still a lack of effective methods to identify the functional genes of J. sigillata. By verifying the model plant tobacco, the pTRV2::JsPDS vector was able to cause photobleaching. This study showed that

Integrated transcriptomics and metabolomics elucidate how arbuscular mycorrhizal fungi alleviate drought stress in Juglans sigillata

Microbiological Research
Walnut (Juglans sigillata), an economically significant ecotype of the Juglans genus in the Juglandaceae family, is cultivated mainly in southwest China, a region prone to seasonal drought. Drought significantly reduced both the yield and quality of walnuts in this area.

Transcriptomic and metabolomic approaches reveal the physiological and biochemical alleviation mechanisms of silicon on aluminum stress in Juglans sigillata

Plant Physiology and Biochemistry
Juglans sigillata, an endemic species in China, serves as a vital local economic resource. Aluminum (Al) stress caused by soil acidification can potentially threaten the growth of J. sigillata. This study aimed to elucidate the mechanism of the alleviation of Al stress by silicon (Si) in J. sigillata.

JsMYB170 modulates flavonols biosynthesis through facilitation of JsFLS1/5 expression in pellicle of Juglans sigillata Dode

Plant Science
J. sigillata produces abundant flavonols such as rutin and myricetin in pellicle, which provide various benefits to human health. However, the transcriptional regulation of flavonols biosynthesis in pellicle of J. sigillata remains unclear. Our study showed that the JsMYB170 is a transcriptional activator involved in the biosynthesis of flavonols in J.

Extraction process, fraction characterization and in vitro bioactivity evaluation of flavonoids from Diaphragma juglandis fructus in Juglans sigillata

Journal of Chromatography A
In this study, total flavonoids were extracted from Diaphragma juglandis fructus (DJF) in Juglans sigillata via ultrasound-assisted extraction using a one-way test and response surface methodology. The optimum conditions for the extraction of flavonoids from DJF were as follows: ultrasound power, 160 W; extraction time, 39 min; liquid/solid ratio, 60 ...

Identification of an Anti-inflammatory Peptide from Walnut ( Juglans sigillata ) Protein and the Effect on DSS-Induced Colitis in Mice

Journal of Agricultural and Food Chemistry
Various proteases were employed to hydrolyze walnut protein, and anti-inflammatory effects of the hydrolysates were evaluated in RAW264.7 cells exposed to lipopolysaccharide. The bromelain hydrolysate, which was further separated using ultrafiltration and RP-HPLC, presented the highest anti-inflammatory effect.
