Exogenous spermidine is enhancing tomato tolerance to salinity–alkalinity stress by regulating chloroplast antioxidant system and chlorophyll metabolism

Background Salinity–alkalinity stress is known to adversely affect a variety of processes in plants, thus inhibiting growth and decreasing crop yield. Polyamines protect plants against a variety of environmental stresses. However, whether exogenous spermidine increases the tolerance of tomato seedlings via effects on chloroplast antioxidant enzymes and chlorophyll metabolism is...

Characterization of cp3 reveals a new bri1 allele, bri1-120, and the importance of the LRR domain of BRI1 mediating BR signaling

Background Since the identification of BRI1 (BRASSINOSTEROID-INSENSITIVE1), a brassinosteroids (BRs) receptor, most of the critical roles of BR in plant development have been assessed using various bri1 mutant alleles. The characterization of individual bri1 mutants has shown that both the extracellular and cytoplasmic domains of BRI1 are important to its proper functioning...

Functional characterization of Arabidopsis thaliana transthyretin-like protein

Background Arabidopsis thaliana transthyretin-like (TTL) protein is a potential substrate in the brassinosteroid signalling cascade, having a role that moderates plant growth. Moreover, sequence homology revealed two sequence domains similar to 2-oxo-4-hydroxy-4-carboxy-5-ureidoimidazoline (OHCU) decarboxylase (N-terminal domain) and 5-hydroxyisourate (5-HIU) hydrolase (C...

Four-and-a-half LIM protein 2 promotes invasive potential and epithelial-mesenchymal transition in colon cancer

Background and Aims: Cancer invasion and metastasis may associate with the phenotype transition called epithelial-mesenchymal transition (EMT). We aim to evaluate the impact of four-and-a-half LIM protein 2 (FHL2) on EMT and invasion of colon cancer. Methods: The functional role of FHL2 in EMT was determined by overexpression or small interfering RNA-mediated depletion of FHL2...

Cloud Model-Based Artificial Immune Network for Complex Optimization Problem

This paper proposes an artificial immune network based on cloud model (AINet-CM) for complex function optimization problems. Three key immune operators—cloning, mutation, and suppression—are redesigned with the help of the cloud model. To be specific, an increasing half cloud-based cloning operator is used to adjust the dynamic clone multipliers of antibodies, an asymmetrical...

Coupling Empowerment Based Application of Extension Method for Geothermal Potential Assessment

Plenty of mathematics researches provide feasibility to calculate the weights of geothermal controlling factors and have been applied in geothermal potential assessment. In order to avoid the disadvantages of subjective and objective weighting calculation methods, an extension theory integrated weighting method was put forward, by combining with the process of AHP and mean...

Brassinosteroid actions in plants

Recent studies on dwarf mutants of Arabidopsis, tomato and pea have provided convincing evidence that brassinosteroids are a unique class of plant hormones that are essential for normal plant growth. Detailed metabolic analyses of these mutants, coupled with thorough molecular and biochemical studies of their corresponding genes and gene products, are essential for a better...

Effect of the Flow Channel Structure on the Nanofiltration Separation Performance

Two kinds of newly designed feed channels, for example, a spiral and a serpentine feed channels, for a bench-scale nanofiltration module were developed to improve the filtration performance. The experiments were carried out with the modules using a commercial flat NF membrane to investigate the effects of Reynolds number (Re) and flow channel structures on the flux of permeate...

An Effective Scheduling-Based RFID Reader Collision Avoidance Model and Its Resource Allocation via Artificial Immune Network

Radio frequency identification, that is, RFID, is one of important technologies in Internet of Things. Reader collision does impair the tag identification efficiency of an RFID system. Many developed methods, for example, the scheduling-based series, that are used to avoid RFID reader collision, have been developed. For scheduling-based methods, communication resources, that is...

The Arabidopsis Homolog of the Mammalian OS-9 Protein Plays a Key Role in the Endoplasmic Reticulum-Associated Degradation of Misfolded Receptor-Like Kinases

The endoplasmic reticulum-associated degradation (ERAD) is a highly conserved mechanism to remove misfolded membrane/secretory proteins from the endoplasmic reticulum (ER). While many of the individual components of the ERAD machinery are well characterized in yeast and mammals, our knowledge of a plant ERAD process is rather limited. Here, we report a functional study of an...

Regulation of Vapor Pressure Deficit by Greenhouse Micro-Fog Systems Improved Growth and Productivity of Tomato via Enhancing Photosynthesis during Summer Season

The role of a proposed micro-fog system in regulating greenhouse environments and enhancing tomato (Solanum lycopersicum L.) productivity during summer season was studied. Experiments were carried out in a multi-span glass greenhouse, which was divided into two identical compartments involving different environments: (1) without environment control and (2) with a micro-fog system...
