Abstract

Auxin/Indole-3-Acetic Acid (Aux/IAA) genes are involved in auxin signaling pathway and play an important role in plant growth and development. However, many studies focus on Aux/IAA gene families and much less known in Bletilla striata. In this study, a total of 27 Aux/IAA genes (BsIAA1-27) were cloned from the transcriptome of Bletilla striata. Based on a phylogenetic analysis of the Aux/IAA protein sequences from B. striata, Arabidopsis thaliana and Dendrobium officinale, the Aux/IAA genes of B. striata (BsIAAs) were categorized into 2 subfamilies and 9 groups. While BsIAAs were more closer to those of D. officinale compared to A. thaliana. EST-SSR marker mining test showed that 4 markers could be stably amplified with obvious polymorphisms among 4 landraces. Our results suggested that BsIAAs were involved in the process of tuber development and provided insights into functional roles of Aux/IAA genes in B. striata and other plants., Graphical Abstract In this paper, we identified the 27 members of the Aux/IAA gene family which can be divided into 2 groups and 9 subfamilies. The similar branches of Aux/IAA proteins had the same or similar motifs, such as genes between BsIAA10 and BsIAA12, BsIAA11 and BsIAA13, BsIAA18 and BsIAA20, indicating that Aux/IAA proteins were conserved. Among them, BsIAAs were more closer to those of D. officinale compared to A. thaliana.

Abstract

This article mainly studies the characteristics of transformer inrush current and the influence of different factors on transformer inrush current. This article states the background and significance of the inrush current, introduces the research status of the inrush current and the suppression technology. The suppression of the inrush current is the root of the problem. The mechanism of the inrush current is derived mathematically from the magnetic flux relationship, and the characteristics of the inrush current are analyzed through its related waveform diagrams. On this basis, the harm of inrush current is introduced. The core method is based on the PSCAD simulation platform to build the inrush current and the circuit to suppress the inrush current, and to set the parameters for simulation model. This article discusses the effects of transformer capacity, closing angle, knee voltage and basic parameters on inrush current.

Abstract

Levulinic acid (LA) can be cost-effectively produced from a vast array of renewable carbohydrate-containing biomaterials. LA could facilitate the commercialization of the polymer poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) and PHBV-based products as carbon substrates. Therefore, this paper focused on the production of PHBV by Ralstonia eutropha with LA for hydroxyvalerate (HV) production, which plays an important role in enhancing the thermal properties of PHBV. Accordingly, the HV content of PHBV varied from 0–40.9% at different concentrations of LA. Stimulation of cell growth and PHBV accumulation were observed when 2–6 g L−1 LA was supplied to the culture. The optimal nitrogen sources were determined to be 0.5 g L−1 ammonium chloride and 2 g L−1 casein peptone. It was determined that the optimal pH for cell growth and PHBV accumulation was 7.0. When the cultivation was performed in large scale (2 L fermenter) with a low DO concentration of 30% and a pH of 7.0, a high maximum dry cell weight of 15.53 g L−1 with a PHBV concentration of 12.61 g L−1 (53.9% HV), up to 81.2% of the dry cell weight, was obtained. The melting point of PHBV found to be decreased as the fraction of HV present in the polymer increased, which resulted in an improvement in the ductility and flexibility of the polymer. The results of this study will improve the understanding of the PHBV accumulation and production by R. eutropha and will be valuable for the industrial production of biosynthesized polymers.
