Deciphering the Interaction between and Pomegranate Fruit Employing Transcriptomics.

Pomegranate fruit dry rot is caused by , also referred as . In order to decipher the induced responses of mature pomegranates inoculated with the pathogen, an RNA-seq analysis was employed. A high number of differentially expressed genes (DEGs) were observed through a three-time series inoculation period.

Toxicity and Lethal Effect of Greenhouse Insecticides on (Coleoptera: Coccinellidae) as Biological Control Agent of (Hemiptera: Aphididae).

Deltamethrin and imidacloprid are commonly used insecticides for controlling sub-sucking insects in greenhouses. However, their application may cause sublethal effects on the aphid coccinellid predator (Coleoptera: Coccinellidae). Here, we study (i) the toxicity and the effect of two sublethal doses (LD and LD) of deltamethrin and imidacloprid on in a laboratory microcosm and (ii) the residual toxicity of the two insecticides in a greenhouse.

The possible bottleneck effect of polyamines' catabolic enzymes in efficient adventitious rooting of two stone fruit rootstocks.

Adventitious rooting is an important plant physiological response utilized in cutting propagation, a procedure with high financial significance. Many endogenous factors are involved, such as plant growth regulators, carbohydrates, minerals, polyamines etc. The objective of the present study was to investigate the role of polyamines and polyamine catabolic enzymes in the bases of softwood cuttings of two Prunus rootstocks, during the early phases of rhizogenesis.

Polyamine homeostasis in tomato biotic/abiotic stress cross-tolerance.

Adverse conditions and biotic strain can lead to significant losses and impose limitations on plant yield. Polyamines (PAs) serve as regulatory molecules for both abiotic/biotic stress responses and cell protection in unfavourable environments. In this work, the transcription pattern of 24 genes orchestrating PA metabolism was investigated in Cucumber Mosaic Virus or Potato Virus Y infected and cold stressed tomato plants.

Spatial and temporal distribution of genes involved in polyamine metabolism during tomato fruit development.

Polyamines are organic compounds involved in various biological roles in plants, including cell growth and organ development. In the present study, the expression profile, the accumulation of free polyamines and the transcript localisation of the genes involved in Put metabolism, such as Ornithine decarboxylase (ODC), Arginine decarboxylase (ADC) and copper containing Amine oxidase (CuAO), were examined during Solanum lycopersicum cv. Chiou fruit development and maturation.
