Storability and Linear Regression Models of Pericarp Browning and Decay in Fifty Litchi ( Sonn.) Cultivars at Room Temperature Storage.

The primary cause for the limited shelf life of litchi fruit is rapid pericarp browning and decay. This study aims to evaluate the storability of 50 litchi varieties and establish a linear regression model for pericarp browning and decay based on 11 postharvest physical and chemical indices after 9 days of storage at room temperature. The results indicated that the average value of the browning index and decay rate significantly increased to 3.

Combined Metabolome and Transcriptome Analyses Unveil the Molecular Mechanisms of Fruit Acidity Variation in Litchi ( Sonn.).

Fruit acidity determines the organoleptic quality and nutritive value of most fruits. In litchi, although the organic acid composition of pulps is known, the molecular mechanisms and genes underlying variation in fruit acidity remain elusive. Herein, developing pulps of two contrasting litchi varieties, Huaizhi (HZ, low-acidity) and Boye_No.

Overexpression of a B-type cytokinin response regulator () reduces plant height in rice.

Cytokinin plays crucial roles in regulating plant growth and development, with the signal transduction mediated by type-A and type-B response regulators (RRs).While much genetic knowledge about RRs on regulating plant height remains unclear. Here, we found that overexpressing an gene (a type-B RR) could reduce plant height in rice compared with the wild type (WT).

Label-free quantitative proteomic analysis revealed a positive effect of ectopic over-expression of PeaT1 from on rice () response to drought.

The protein elicitor PeaT1 was found in and exerted broad spectrum resistance in wheat, cotton, and rice. Recently, we found that overexpressing rice (OE) could enhance plant drought tolerance. Elucidating some elevated drought stress-related proteins and associated mechanisms is inevitable for improving drought tolerance in rice.

Overexpression of the Elicitor Gene from Improves Drought Tolerance in Rice Plants Interaction with a Myo-Inositol Oxygenase.

Abiotic stresses, especially drought, seriously threaten cereal crops yields and quality. In this study, we observed that the rice plants of overexpression the gene showed enhanced drought stress tolerance and increased the survival rate following a drought treatment. In -overexpressing (PeaT1OE) plants, abscisic acid and chlorophyll content significantly increased, while the malondialdehyde (MDA) content decreased compared with the wild-type plants.

Plant Immunity Inducer Development and Application.

Plant immunity inducers represent a new and rapidly developing field in plant-protection research. In this paper, we discuss recent research on plant immunity inducers and their development and applications in China. Plant immunity inducers include plant immunity-inducing proteins, chitosan oligosaccharides, and microbial inducers.

Phosphate solubilization and promotion of maize growth by Penicillium oxalicum P4 and Aspergillus niger P85 in a calcareous soil.

Alternative tactics for improving phosphorus nutrition in crop production are needed in China and elsewhere, as the overapplication of phosphatic fertilizers can adversely impact agricultural sustainability. Penicillium oxalicum P4 and Aspergillus niger P85 were isolated from a calcareous soil in China that had been exposed to excessive application of phosphatic fertilizer for decades. Each isolate excreted a number of organic acids into, acidified, and solubilized phosphorus in a synthetic broth containing insoluble tricalcium phosphate or rock phosphate.

[Screening, identification of P-dissolving fungus P83 strain and its effects on phosphate solubilization and plant growth promotion].

Objective: To isolate phosphate-solubilizing microorganisms from farmland, and to provide P-solubilizing microbial resource for bio-fertilizer production.

Methods: Phosphate-solubilizing fungus was identified using morphological and cultural characteristics and ITS rDNA sequence analysis. The phosphate-solubilizing capacity of strain P83 was measured by Petri dishes, broth medium and soil pot experiment.
