The search resulted in a total of 954 records. After screening and full-text review, 17 articles were included in this review four observational studies, 10 case reports, and 3 case series. Based on the observational studies, a total of 38 Patients with SE have been reported. KD was successful in achieving cessation of SE in 31 Patients (82%). The most common adverse effects reported were metabolic acidosis, hyperlipidemia, and hypoglycemia. The current limited evidence suggests that KD might be considered as an option for adult patients with SE. Although promising, the results need to be interpreted with caution due to the inherent bias, confounding and small sample size of the included studies. A randomized controlled trial is recommended to establish role of KD in the management of SE in adults. © 2019 The Authors.

Chromochloris zofingiensis is a unicellular green alga that is able to accumulate high amounts of ketocarotenoids including astaxanthin, canthaxanthin and ketolutein when growing heterotrophically or mixotrophically with glucose as a carbon source. Here we elucidate the ketocarotenoid biosynthesis pathway in C. zofingiensis by analyzing five algal mutants. The mutants were shown to have a single nucleotide insertion or substitution in β-carotene ketolase (BKT) gene 1, which resulted in a lack of ketocarotenoid production in Cz-bkt1-1, and decreased ketocarotenoid content in the other four mutants. These mutants accumulated much higher amounts of non-ketocarotenoids (β-carotene, zeaxanthin and lutein). Interestingly, the Cz-bkt1-5 mutant synthesized 2-fold the ketolutein and only 1/30 of the canthaxanthin and astaxanthin as its parent strain, suggesting that the mutated BKT1 exhibits much higher activity in catalyzing lutein to ketolutein but lower activity in ketolating β-carotene and zeaxanthin. Mutant and WT BKT2 gene sequences did not differ. Taken together, we conclude that BKT1 is the key gene involved in ketocarotenoid biosynthesis in C. zofingiensis. Our study provides insight into the biosynthesis of ketocarotenoids in green algae. Furthermore, Cz-bkt1 mutants may serve as a natural source for the production of zeaxanthin, lutein, and β-carotene. © 2019 Kunming Institute of Botany, Chinese Academy of Sciences.

However, members of the LBD gene family have yet to be identified in Brassica rapa var. rapa. In the present study, fifty-nine LBD genes were identified and distributed on 10 chromosomes. The BrrLBD proteins are predicted to encode hydrophobic polypeptides between 118 and 394 amino acids in length and with molecular weights ranging from 13.31 to 44.24 kDa; the theoretical pI for these proteins varies from 4.83 to 9.68. There were 17 paralogous gene pairs in the BrrLBD family, suggesting that the amplification of the BrrLBD gene family involved large-scale gene duplication events. Members of the BrrLBD family were divided into 7 subclades (class I a to e, class II a and b). Analysis of gene structure and conserved domains revealed that most BrrLBD genes of the same subclade had similar gene structures and protein motifs. The expression profiles of 59 BrrLBD genes were determined through Quantitative Real-time fluorescent PCR (qRT-PCR). Most BrrLBD genes in the same subclade had similar gene expression profiles. However, the expression patterns of 7 genes differed from their duplicates, indicating that although the gene function of most BrrLBD genes has been conserved, some BrrLBD genes may have undergone evolutionary change. © 2019 Kunming Institute of Botany, Chinese Academy of Sciences.

The present study investigates the effects of CO2 enrichment (to 800 μmol mol-1) on the physiology of soybean plants and the nutritional value of their seeds under growth chamber conditions. selleck The photosynthesis of soybean was significantly promoted by E[CO2] at all growth stages, but leaf area and specific leaf weight were not affected. The levels of mineral elements in the leaves decreased under E[CO2]. The soil properties after soybean cultivation under E[CO2] were not affected, except for a decrease in available potassium. Moreover, the levels of soluble sugars in the seeds were not affected by E[CO2], but the levels of natural antioxidants decreased. In addition, the level of oleic acid decreased under E[CO2]. However, levels of fatty acid peroxidation and saturation were maintained. In conclusion, E[CO2] appears to have positive effects on the growth of cultivated soybean plants, but its influence on the nutritional values of soybean seeds is complex. © 2019 Kunming Institute of Botany, Chinese Academy of Sciences.

In earlier studies, ROS were considered toxic byproducts of aerobic metabolism. In recent years, it has become clear that ROS act as plant signaling molecules that participate in various processes such as growth and development. Several studies have elucidated the roles of ROS from seed germination to senescence. However, there is much to discover about the diverse roles of ROS as signaling molecules and their mechanisms of sensing and response. ROS may provide possible benefits to plant physiological processes by supporting cellular proliferation in cells that maintain basal levels prior to oxidative effects. Although ROS are largely perceived as either negative by-products of aerobic metabolism or makers for plant stress, elucidating the range of functions that ROS play in growth and development still require attention. © 2019 Kunming Institute of Botany, Chinese Academy of Sciences.
