Genome Mining Reveals Biosynthesis of the Antifungal Lipopeptaibols, Texenomycins, through a Hybrid PKS-NRPS System, in the Fungus .

Texenomycins are a family of linear lipopeptaibols with a long polyketide side chain at the N-terminus and 21 amino acid residues at the -terminus, presenting demonstrated potential as antibiotics against plant fungal pathogens. In this study, texenomycins were identified and isolated from the fungus strain TTI-0396 and showed effective antifungal properties against two plant pathogens and . Through analysis of the whole-genome data of strain TTI-0396, we discovered a hybrid PKS-NRPS system with the polyketide synthase (PKS: TexQ), thioesterase (TexO), acyl-CoA ligase (TexI), and three nonribosomal peptide synthetases (NRPSs: TexG, TexJ, TexV) in the gene cluster that were proposed to be responsible for the biosynthesis of texenomycins and another related lipopeptaibol, lipohexin.

Study on the changes of miRNAs and their target genes in regulating anthocyanin synthesis during purple discoloration of cauliflower curd under low temperature stress.

Introduction: Cauliflower is widely cultivated all over the world is attributed to its palatable flavor, high levels of anti-cancer compounds, and diverse array of nutrients. Exposure to extremely cold stress during production can result in a more frequent occurrence of purple discoloration in cauliflower curds. In response to cold stress, plants naturally produce anthocyanins to eliminate reactive oxygen species (ROS) generated as a defense mechanism.

Potatoes are a globally important crop with high nutritional value. Different potato varieties display notable variations in color, texture, and nutrient composition. However, the influence of cooking on tuber color, texture, and metabolites has not been comprehensively explored.

Comparation of pheromone-binding proteins 1 and 2 of Spodoptera frugiperda in perceiving the three sex pheromone components Z9-14:Ac, Z7-12: Ac and Z11-16: Ac.

Pheromone-binding proteins (PBPs) are mainly responsible for binding and transporting hydrophobic pheromone molecules across the aqueous sensilla lymph to the receptor proteins. The preference of each PBP is believed to be different for each pheromone component within a single species. Significantly higher expression level of PBP1 and PBP2 in the male antennae of Spodoptera frugiperda suggesting that SfruPBP1 and SfruPBP2 might play important roles in pheromone perception.

Integrated genome-wide association and transcriptomic studies reveal genetic architecture of bulb storability of plentiful garlic germplasm resources.

Garlic is a widely utilized condiment and health product. However, garlic bulbs are prone to quality deterioration resulting in decrease of economic value during postharvest. In this study, the storability of 501 garlic accessions worldwide was evaluated based on the examination of decay index (DI), decay rate, sprouting rate, and bud-to-clove ratio in two consecutive years.

Candidate genes associated with low temperature tolerance in cucumber adult plants identified by combining GWAS & QTL mapping.

Fruit quality and yield are reduced when cucumber (Cucumis sativus L.) plants are exposed to low temperature (LT) stress, yet, the inheritance and genes linked to cold tolerance in adult plants have not been reported yet. Here, the LT-tolerance of 120 cucumber accessions representing four ecotypes were evaluated by GWAS, and also, in 140 recombinant inbred lines (RILs) derived from a biparental cross.

Dissection of major QTLs and candidate genes for seedling stage salt/drought tolerance in tomato.

Background: As two of the most impactful abiotic stresses, salt and drought strongly affect tomato growth and development, especially at the seedling stage. However, dissection of the genetic basis underlying salt/drought tolerance at seedling stage in tomato remains limited in scope.

Results: Here, we reported an analysis of major quantitative trait locus (QTL) and potential causal genetic variations in seedling stage salt/drought tolerance in recombinant inbred lines (n = 201) of S.

Whether niche changes promote the evolution of species: a case study of in Asia and North America.

Ecological changes have been observed to promote rates of lineage diversification, yet the precise roles of ecological factors, species evolution, and environmental variability in driving species diversity remain research hot spots. The association between ecological change and lineage diversification, particularly with regard to the size of the time scale, remains poorly understood. To explore whether ecological change facilitates species evolution, we focused on the unique family Paeoniaceae, which encompasses both herbaceous and woody taxa, to investigate the evolutionary rates.

Lily (Lilium spp.) LhERF061 suppresses anthocyanin biosynthesis by inhibiting LhMYBSPLATTER and LhDFR expression and interacting with LhMYBSPLATTER.

Ethylene has an essential function in the biosynthesis of anthocyanin. However, the molecular mechanism through which ethylene impacts the color of lily flower remains little appreciated. This study identified LhERF061, a dehydration-responsive element-binding (DREB family) transcription factor that suppresses anthocyanin biosynthesis in response to ethylene in lilies.

Telomere-to-telomere genome assembly of eggplant (Solanum melongena L.) promotes gene fine localization of the green stripe (GS) in pericarp.

Fruit appearance of eggplant is a key commercial trait, and the precise selection of new varieties with diverse aesthetics aligns with current breeding objectives. However, functional genomics research in eggplant remains underdeveloped. Here, we assembled the first telomere-to-telomere (T2T) eggplant genome, as well as chloroplast and mitochondrial genomes for the inbred line 'NO211'.

A natural variant of NON-RIPENING promotes fruit ripening in watermelon.

The regulation of non-climacteric fruit ripening by the transcription factor NON-RIPENING (NOR) is poorly understood. Here, we identified that the NOR homolog in the non-climacteric fruit watermelon (Citrullus lanatus) is located within the selective sweep and sweetness quantitative trait locus that was selected during domestication from landraces to cultivars. ClNOR knockout substantially delayed fruit ripening, and the fruits of the knockout plants had lower abscisic acid (ABA) levels, lighter colored flesh, and were less sweet compared to wild type.

Alteration in microbes changed the contents of oviposition-deterrent pheromones on the egg surface.

Microorganisms symbiotic with insects, whether permanently or temporarily, play a crucial role in the nutrition, development, reproduction, defence, and metamorphosis regulation. In some Lepidoptera, oviposition-deterrent pheromones (ODPs) on egg surface were used by pregnant females to modify the behaviour of conspecifics to avoid excessive competition for limited resources. In this study, we constructed four different groups, including, OH, OA, SH, and OA, which either feed on different hosts or grow in different environments.

Releasing a sugar brake generates sweeter tomato without yield penalty.

In tomato, sugar content is highly correlated with consumer preferences, with most consumers preferring sweeter fruit. However, the sugar content of commercial varieties is generally low, as it is inversely correlated with fruit size, and growers prioritize yield over flavour quality. Here we identified two genes, tomato (Solanum lycopersicum) calcium-dependent protein kinase 27 (SlCDPK27; also known as SlCPK27) and its paralogue SlCDPK26, that control fruit sugar content.

Effects of blanching cultivation on the chemical composition and nutritional quality of Chinese chive.

Blanching is an agricultural practice where vegetables are cultivated in darkness to prevent photosynthesis, thereby modifying their colour, texture, and flavor. The technique is popularly employed in Chinese chive (CC). Blanched Chinese chive (BCC) is renowned for its pale-yellow appearance, delicate flavor, and culinary-medicinal values; nonetheless, how blanching alters the chemical composition largely remains intangible.

PlZAT10 binds to the ABA catabolism gene PlCYP707A2 promoter to mediate seed dormancy release in Paeonia lactiflora.

PlZAT10-PlCYP707A2 module promotes Paeonia lactiflora seeds germination. The herbaceous peony (Paeonia lactiflora) seeds exhibit double dormancy in the epicotyl and hypocotyl, which significantly inhibits the process of cultivation and breeding of new varieties. Nevertheless, the molecular mechanism underlying seed dormancy release in P.
