Abstract Carotenoids are isoprenoid metabolites synthesized de novo in all photosynthetic organisms. essential for plants with diverse functions photosynthesis, photoprotection, pigmentation, phytohormone synthesis, and signaling. They also critically important humans as precursors of vitamin A synthesis dietary antioxidants. The vital roles carotenoids to have prompted significant progress toward our understanding carotenoid metabolism regulation. New regulators novel continuously revealed. This review focuses on current status highlights recent advances comprehension the intrinsic multi-dimensional regulation accumulation. We discuss functional evolution carotenoids, agricultural horticultural application, some key areas future research.

Phytoene synthase (PSY) catalyzes the first committed step in carotenoid biosynthesis pathway and is a major rate-limiting enzyme of carotenogenesis. PSY highly regulated by various regulators factors to modulate response diverse developmental environmental cues. Because its critical role controlling total amount synthesized carotenoids, has been extensively investigated engineered plant species. However, much remains be learned on multifaceted regulatory control catalytic efficiency for enrichment crops. Here, we present current knowledge basic biology, functional evolution, dynamic regulation, metabolic engineering PSY. We also discuss open questions gaps stimulate additional research this most studied gene/enzyme carotenogenic pathway.

Sweet potato is one of the most economically important crops for addressing global food security and climate change issues, especially under conditions extensive agriculture, such as those found in developing countries. However, osmotic stress negatively impacts agronomic economic productivity sweet cultivation by inducing several morphological, physiological, biochemical changes. Plants employ many signaling pathways to respond water modifying their growth patterns, activating antioxidants, accumulating suitable solutes chaperones, making proteins. These metabolic, genetic modifications can be employed best indicators choosing drought-tolerant genotypes. The main objective breeding regions world, affected drought, obtain varieties that combine drought tolerance with high yields. In this regard, study physiological features certain implementation resistance measures. Adapted genotypes selected improved particular growing using tools tolerance-related selection criteria. By regulating genetics way, creation drought-resistant may become cost-effective smallholder farmers. This review focuses on mechanisms potato, effects its productivity, crop management strategies mitigation, traditional molecular methods tolerance, use biotechnological increase drought.

Biotic and abiotic stresses negatively affect the yield overall plant developmental process, thus causing substantial losses in global sweet potato production. To cope with stresses, has evolved numerous strategies to tackle ever-changing surroundings biological environmental conditions. The invention of modern sequencing technology latest data processing analysis instruments paved way integrate information from different approaches helps understand system biology more precisely. advancement omics technologies accumulated provided a great source at all levels (genome, transcript, protein, metabolite) under stressful These molecular tools facilitate us better plant's responses stress signaling help process/integrate encoded within plants. This review briefly addresses utilizing for deciphering adaptive mechanisms potatoes' biotic tolerance via functional genomics, transcriptomics, proteomics, metabolomics. also provides powerful reference complex, well-coordinated genetic regulatory networks comprehend phenotypic cellular/molecular level various stimuli, accelerating design stress-resilient engineering approaches.

Tocopherols are lipid-soluble compounds regarded as vitamin E and they function antioxidants in scavenging lipid peroxyl radicals quenching reactive oxygen species (ROS). In our previous studies, we isolated five tocopherol biosynthesis genes from sweetpotato (Ipomoea batatas [L.] Lam) plants including 4-hydroxyphenylpyruvate dioxygenase (IbHPPD). HPPD is the first regulatory enzyme serves to catalyze steps α-tocopherol plastoquinone by converting (HPP) homogentisic acid (HGA). this study, generated transgenic overexpressing IbHPPD under control of cauliflower mosaic virus (CaMV) 35S promoter (referred HP plants) via Agrobacterium-mediated transformation understand sweetpotato. Three lines (HP3, HP14 HP15) with high transcript levels were selected for further characterization. Compared non-transgenic (NT) plants, exhibited enhanced tolerance multiple environmental stresses, salt, drought, oxidative stresses. addition, showed increased herbicide sulcotrione, which involved inhibition HPPD. Interestingly, after stress treatments, also higher abscisic (ABA) contents than NT plants. Under dehydrated condition, displayed an elevated content 19-27% leaves compared These results indicate that abiotic related inducing enhancement ABA contents.

Botanical oils are staple consumer goods globally, but as a by-product of oil crops, meal is low utilization value and prone to causing environmental problems. The development proteins in into bioactive peptides, such Perilla peptide, through biotechnology can not only solve problems, also create more valuable nutritional additives. In the present work, hydrolysis process protein suitable for industrial application was optimized with response surface methodology (RSM) on basis single-factor experiments. Alcalase firstly selected best-performing among four proteases. Then, based Alcalase, optimal conditions were follows: enzyme concentration 7%, temperature 61.4 °C, liquid-solid ratio 22.33:1 (mL/g) time 4 h. Under these conditions, degree (DH) 26.23 ± 0.83% DPPH scavenging capacity hydrolysate 94.15 1.12%. soluble peptide or rose up 5.24 0.05 mg/mL, ideal yield which estimated be 17.9%. SDS-PAGE indicated that large proportion new bands small molecular weights appeared, different from original protein. data contributed further, specific research separation, purification identification antioxidant results showed could peptides high activity potential applications natural antioxidants food industry.
