Conventional extraction techniques like steam distillation and cold pressing typically yield 0.1-2.0% EO depending on plant species, part used, and method applied.

Colobanthus quitensis is one of the two extremophile vascular species native to Antarctica and is recognized for its biotechnological potential in environmental stress studies and as a bioindicator of climate change. However, the manifestation of physiological deterioration in the seeds of this species remains unknown. This study aimed to analyze the physiological changes occurring in C. quitensis seeds during the deterioration process. To achieve this, the accelerated aging method was applied to evaluate variations in germination and various biochemical indicators between aged and non-aged seeds. The results showed that the germination percentage, mean germination time, time required to reach 50% germination, and germination speed coefficient significantly decreased with seed deterioration. However, once the seed coat is broken, germination may be enhanced. Additionally, total sugar content decreased significantly with aging, while indole-3-acetic acid content increased.

VrMYB90 acted upstream of VrANR by binding to the promoter of VrANR and inhibiting the expression of VrANR, thus regulating negatively the biosynthesis of proanthocyanins. Anthocyanin reductase (ANR), the enzyme responsible for converting anthocyanidins to their corresponding 2,3-cis-flavan-3-ols, which is crucial to balance the anthocyanins and proanthocyanidins (PAs) level. In this study, significant differences were observed in the contents of anthocyanins and PA between the two cultivars. We identified a structural gene VrANR and a MYB transcription factor VrMYB90 that acts upstream of VrANR based on transcriptomic data analysis. Both of the two factors played key roles in PA accumulation in mung bean. Overexpressing VrANR in mung bean hairy roots led to a higher PA accumulation when compared with empty vector. Furthermore, overexpression VrANR in the Arabidopsis ban (anr) mutants increased PA content while reducing anthocyanin levels. Yeast-one-hybridization, β-glucuronidase (GUS) assay and dual-luciferase (LUC) reporter assays revealed that VrMYB90 (a positive regulator in anthocyanin) could bind to the VrANR promoter to repress its expression and then repress PA synthesis. Determination of transcript level of VrANR in VrMYB90 transgenic mung bean also proved that VrMYB90 inhibited the expression of VrANR. Above all, our present results suggested that VrMYB90 can repress the transcription of VrANR to play a negative role in the PAs accumulation in mung bean.

Strigolactones (SLs), a group of carotenoid-derived plant hormones, regulate plant stress tolerance. Lycium ruthenicum Murr., a key native halophyte in northwestern China's arid oasis-desert ecotone with rich nutritional and medicinal value, faces compromised seedling survival under high-salinity alkali conditions despite its role in ameliorating salinized soils and boosting rural economies via artificial cultivation. However, the specific effects and mechanisms of exogenous strigolactone GR24 on L. ruthenicum seedlings under salt stress remain underexplored, representing a critical research gap in stress adaptation. This study utilized hydroponic cultivation to assess the influence of GR24 on L. ruthenicum seedlings exposed to high salinity (250 mM), with a focus on growth parameters, leaf structure, and the AsA-GSH cycle. Results showed that 5 μM exogenous GR24 treatment effectively alleviated salt stress, with significant increases in plant morphological traits, cell activity, and chlorophyll fluorescence compared to untreated seedlings. In addition, GR24 treatment enhanced the activity of the AsA-GSH cycle, effectively scavenging free radicals. Furthermore, 5 μM GR24 treatment improved chloroplast ultrastructure, thereby enhancing subcellular stability and the functionality of the photosynthetic apparatus. Transcriptomic analysis indicated the amount of DEGs of L. ruthenicum by GR24 treatment was enriched in metabolic processes, signal transduction, metabolism, synthesis and resistance.

Volatile-mediated plant-to-plant signalling in response to herbivory is well documented, but its contingency on abiotic factors and variation in herbivore load is poorly understood. To address this gap, we investigated how soil salinity levels and herbivore load may influence signalling effects on plant defences and resistance in wild cotton (Gossypium hirsutum), using the specialist herbivore Alabama argillacea (cotton leafworm). We conducted a greenhouse experiment where plants were grouped in triplets: one acting as the emitter and the other two as receivers. Each triplet was placed inside a mesh cage. Both emitters and receivers were exposed to either ambient (control) or augmented soil salinity. Emitters at each salinity level underwent three treatments: no damage, damage by one or three caterpillars. After 48 h of damage, we collected VOCs from the emitters, which were removed from the cages at 72 h. Afterwards, we damaged the receiver plants to test for the priming effects on the induction of extrafloral nectar (EFN) and terpenoid aldehyde content, as well as on resistance to herbivory. Herbivory increased VOC emissions significantly under high herbivory load, but salinization reduced this effect. Receivers exposed to VOC from plants with high herbivore load induced a greater EFN concentration compared to those exposed to control emitters, an effect that disappeared under augmented salinity. Soil salinity did not affect the signalling effect on terpenoid aldehyde content but did influence herbivore resistance. These findings suggest that signalling depends on herbivore load and soil salinity, with the latter enhancing or affecting the induction depending on the plant defense traits.</p>","PeriodicalId":20177,"journal":{"name":"Planta","volume":"262 3","pages":"64"},"PeriodicalIF":3.8,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144732788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we focused on a maize mutant with the segregation of pale green and stunted phenotypes. Genetic analysis showed that these traits were controlled by two independent recessive genes. Using bulked segregant analysis (BSA) and whole-genome sequencing (WGS), three candidate genes were identified for the stunted trait. For the pale green trait, Zm00001eb165700 (chloroplastic polypeptide chain release factor 1, ZmcpRF1) was identified as the only candidate, harboring a missense mutation (c.836G > A|p.G279E). Allelic validation of ZmcpRF1 using another maize mutant with a stop-gain mutation (showing an albino phenotype) further supported this association. The pale green mutant exhibited decreased chlorophyll content, increased relative conductivity (REC), and abnormal chloroplast morphology as compared to normal green plants. This mutant began to wilt at the three-leaf stage and died rapidly by the four-leaf stage. Expression analysis revealed that ZmcpRF1 is predominantly expressed in leaves and is subcellularly localized to chloroplasts.
