Northeastern states of India are known for unique landraces of Capsicum spp. with geographical indications. However, little information is available about these valuable landraces of chillies. Surveys and collections were carried out in niche areas to find out their ecology and diversity through morphological traits and molecular analysis using microsatellite markers. Our result characterized the ecology of niche areas as cool (11.0°C-20.7°C) and humid (>60% relative humidity) climates for dalle-chilli ( Capsicum annuum L...

For the first time, kinetic thermomagnetic extraction is a novel approach presented in this work. It required the application of four distinct variables: rotation speed (50, 75, and 100 rpm), magnetic field (0.8, 1.2, and 1.6 T), time interval (30, 60, and 90 min), and temperature (45, 55, and 65°C). Numerous phytochemical categories were detected in the 81 crude chloroform extracts of green sweet bell pepper seeds that were collected, according to phytochemical analysis. Nine extracts were discovered to be linked to the coumarin chemical class and to have the same two extraction parameters: a 90-minute extraction duration and a 55°C extraction temperature...

Alternative splicing (AS) is a widely observed phenomenon in eukaryotes that plays a critical role in development and stress responses. In plants, the large number of RNA-seq datasets in response to different environmental stressors can provide clues for identification of condition-specific and/or common AS variants for preferred agronomic traits. We report RNA-seq datasets (350.7 Gb) from Capsicum annuum inoculated with one of three bacteria, one virus, or one oomycete and obtained additional existing transcriptome datasets...

BACKGROUND: The presence of oxygen in the growth medium is absolutely essential for root development and the overall metabolic processes of plants. When plants do not have an adequate oxygen supply for respiration, they can experience a condition known as hypoxia. In order to investigate the impact of different nitrogen forms and varying oxygen levels in nutrient solutions on the growth, photosynthesis, and chlorophyll fluorescence parameters of bell pepper plants, a comprehensive study was conducted...

The pepper mutants ('221-2-1a' and '1559-1-2h') with very low pungency were genetically characterized. The Pun4 locus, responsible for the reduced pungency of the mutant fruits, was localized to a 208 Mb region on chromosome 6. DEMF06G16460, encoding 3-ketoacyl-CoA synthase, was proposed as a strong candidate gene based on the genetic analyses of bulked segregants, DEG, and expression analyses. Capsaicinoids are unique alkaloids present in pepper (Capsicum spp.), synthesized through the condensation of by-products from the phenylpropanoid and branched-chain fatty acid pathways, and accumulating in the placenta...

Biomass-derived oligo- and polysaccharides may act as elicitors, i.e., bioactive molecules that trigger plant immune responses. This is particularly important to increase the resistance of plants to abiotic and biotic stresses. In this study, cellulose nanofibrils (CNF) gels were obtained by TEMPO-mediated oxidation of unbleached and bleached kraft pulps. The molecular structures were characterized with ESI and MALDI MS. Analysis of the fine sequences was achieved by MS and MS/MS of the water-soluble oligosaccharides obtained by acid hydrolysis of the CNF gels...

Plant glutamate receptors (GLRs) are integral membrane proteins that function as non-selective cation channels, involved in the regulation of developmental events crucial in plants. Knowledge of these proteins is restricted to a few species and their true agonists are still unknown in plants. Using tomato SlGLRs, a search was performed in the pepper database to identify GLR sequences in habanero pepper ( Capsicum chinense Jacq.). Structural, phylogenetic, and orthology analysis of the CcGLRs, as well as molecular docking and protein interaction networks, were conducted...

Superoxide and hydrogen peroxide are reactive oxygen species (ROS) involved in the oxidation of multiple biological molecules and the signaling processes during plant growth and stress response. Thus, control of ROS is fundamental for cell survival and development, with superoxide dismutase (EC 1.15.1.1, SOD) being one of the main enzymes involved. Different isoforms of SOD catalyze the dismutation of superoxide (O2 .- ) to hydrogen peroxide (H2 O2 ) and oxygen (O2 ), such as Mn-SODs, Cu,Zn-SODs, and Fe-SODs...

Two glycosyltransferase genes belonging to UGT88 family were identified to have 6'-deoxychalcone 4'-glucosyltransferase activity in dahlia. 6'-Deoxychalcones (isoliquiritigenin and butein) are important pigments for yellow and orange to red flower color. 6'-Deoxychalcones are glucosylated at the 4'-position in vivo, but the genes encoding 6'-deoxychalcone 4'-glucosyltransferase have not yet been identified. In our previous study, it was indicated that snapdragon (Antirrhinum majus) chalcone 4'-O-glucosyltransferase (Am4'CGT) has isoliquiritigenin 4'-glucosylation activity...

In recent years, the fungal disease 'pepper stem rot', contracted from the soil-borne pathogen sclerotium rolfsii, has been increasing year by year, causing significant losses to the pepper (Capsicum annuum L.) industry. To investigate the infection mechanism of stem rot, the fungus S. rolfsii was used to infect the roots of pepper plants, and was found to affect root morphology and reduce root activity, which subsequently inhibited root growth and development. With fungal infestation, its secretions (oxalic acid, PG and PMG enzyme) were able to break normal tissues in the stem base and induced the burst of the active oxygen, which leads to injury aggravation...

In capsaicin biosynthesis, vanillin aminotransferase (VAMT; EC 2.6.1.119) catalyzes the conversion of vanillin (V) to vanillylamine (VA). In vitro analysis of the recombinant VAMT enzyme has been reported; however, this enzyme catalyzed only the V-forming reaction and not the VA-forming reaction, which is inconsistent with the postulated pathway for capsaicin biosynthesis. In this study, we expressed, purified, and characterized functional recombinant VAMT of Capsicum chinense cv. Habanero from an Escherichia coli strain...

Under stress conditions, plants modulate their internal states and initiate various defence mechanisms to survive. The ubiquitin-proteasome system is one of the critical modules in these mechanisms, and Plant U-Box proteins play an important role in this process as E3 ubiquitin ligases. Here, we isolated the Plant U-box 24 gene CaPUB24 (Capsicum annuum Plant U-Box 24) from pepper and characterized its functions in response to drought stress. We found that, compared to the other CaPUBs in the same group, the expression of CaPUB24 was significantly induced by drought stress...
