Genome-Wide Identification of the Gene Family in L. and Response to Drought Stress.

Caffeic acid O-methyltransferase (), as a multifunctional enzyme involved in various physiological and biochemical processes in lignin metabolism, plays an important role in a plant's response to stress. In this study, we isolated family members from the walnut genome by bioinformatics and analyzed their physicochemical properties and their expression under drought stress to provide gene resources for drought resistance in walnut. The results showed that 33 genes were identified from walnuts and distributed on different chromosomes.

Molecular cloning and functional characterization in response to saline-alkali stress of the gene in .

Soil salinization is one of the major environmental factors that restrict plant growth and development. Zeaxanthin epoxidase (ZEP) functions in ABA biosynthesis and the xanthophyll cycle and has a vital role in plant responses to various environmental stresses. It was found by quantitative real-time PCR (qRT-PCR) that responded to saline-alkali stress and showed the highest expression at 48 h of saline-alkali stress, which was 14.

Transcription factors and plant hormones mediate wax metabolism in response to drought stress.

Plants have, throughout evolution, developed a hydrophobic cuticle to protect them from various stresses in the terrestrial environment. The cuticle layer is mainly composed of cutin and cuticular wax, a mixture of very-long-chain fatty acids and their derivatives. With the progress of transcriptome sequencing and other research methods, the key enzymes, transporters and regulatory factors in wax synthesis and metabolism have been gradually identified, especially the study on the regulation of wax metabolism by transcription factors and others in response to plant stress has become a hot topic.

Transcription factors dealing with Iron-deficiency stress in plants: focus on the bHLH transcription factor family.

Iron (Fe), as an important micronutrient element necessary for plant growth and development, not only participates in multiple physiological and biochemical reactions in cells but also exerts a crucial role in respiration and photosynthetic electron transport. Since Fe is mainly present in the soil in the form of iron hydroxide, Fe deficiency exists universally in plants and has become an important factor triggering crop yield reduction and quality decline. It has been shown that transcription factors (TFs), as an important part of plant signaling pathways, not only coordinate the internal signals of different interaction partners during plant development, but also participate in plant responses to biological and abiotic stresses, such as Fe deficiency stress.

Transcriptome analysis reveals wax and phytohormone metabolism potentially involved in shooting shrivelling of apple branches overwinter.

Shoot shrivelling severely threatens growth and development of deciduous trees in the northern hemisphere, and we observed that there was a significant difference in shoot shrivelling rate between different apple varieties in practice. In this study, we investigated the anatomical and physiological characteristics of branches from different germplasm resources combined with an analysis of the transcriptome. Transcriptomes of samples treated in the initial dormancy, deep dormancy and freeze-thaw periods were generated and characterised.

Transcriptomic analysis reveals GA is involved in regulating flavonoid metabolism in grape development for facility cultivation.

Gibberellin, as one of the pivotal plant growth regulators, can improve fruit quality by altering fruit size and secondary metabolite content. Flavonoids are the most abundant secondary metabolites in grapes, which influence the color and quality of the fruit. However, the molecular mechanism of whether and how GA affects flavonoid metabolism has not been reported, especially for the 'Red globe' grape with delayed cultivation in Hexi corridor.

Genome-wide identification of the CER1 gene family in apple and response of MdCER1-1 to drought stress.

Plant cuticular wax was a major consideration affecting the growth and quality of plants through protecting the plant from drought and other diseases. According to existing studies, CER1, as the core enzyme encoding the synthesis of alkanes, the main component of wax, can directly affect the response of plants to stress. However, there were few studies on the related functions of CER1 in apple.

Molecular cloning and functional characterization of MhHEC2-like genes in Malus halliana reveals it enhances Fe (iron) deficiency tolerance.

The basic helix-loop-helix (bHLH) family, as one of the largest families of transcription factors (TFs) in plants, plays crucial roles in regulating growth, development, and abiotic stress responses. However, studies on the association of the bHLH genes with apple iron (Fe) deficiency are limited. Here, multiple bHLH genes that responded to Fe deficiency were selected for quantitative real-time PCR in Malus halliana.

Effect of PVC film pretreatment on performance and lamination of wood-plastic composite plywood.

In order to solve the practical problem of heat transfer during the hot pressing process of a novel wood-plastic composite plywood, this paper investigates the perforation treatment of polyvinyl chloride (PVC) plastic films and their plywood composites. The PVC films were pretreated by the physical punching method, and the effects of PVC perforation diameter, hot pressing time and hot pressing temperature on the mechanical properties of the plywood composites were investigated by orthogonal experimental design. The results showed that the optimum hot pressing time was 7 min, the hot pressing temperature was 170 °C, and the PVC perforation diameter was 15 mm for the optimum mechanical properties.

Lumbar spondylolisthesis is a risk factor for osteoporotic vertebral fractures: a case-control study.

Objective This study aimed to identify the risk factors for vertebral compression fractures in patients with osteoporosis. Methods A total of 864 patients with osteoporosis were enrolled in a retrospective study from February 2010 to June 2016. Patients with diseases, such as pathological fractures, high-energy direct injury to the thoracic or lumbar vertebrae, and severe spinal deformity, were excluded.

Potential risk factors for poor outcome after anterior surgery for patients with cervical ossification of the posterior longitudinal ligament.

Objective: Our purpose here was to identify risk factors of poor outcome after anterior operation in patients with cervical ossification of the posterior longitudinal ligament (OPLL).

Methods: This study retrospectively reviewed 98 patients who underwent anterior surgery for improving neurological symptoms. The Japanese Orthopedic Association (JOA) recovery rate <50% was defined as poor surgical outcome.

Predictors of Deterioration in Sagittal Balance Following Long Fusion Arthrodesis to L5 in Patients with Adult Scoliosis.

BACKGROUND The aim of this study was to identify the predictors of deterioration in sagittal balance in patients with adult scoliosis following long fusion arthrodesis to L5. MATERIAL AND METHODS A retrospective clinical study included 63 patients with adult scoliosis who underwent long fusion arthrodesis to L5, between February 2005 and May 2015. Radiological imaging values included the angle of lumbar lordosis (LL), and the angle of pelvic incidence (PI).
