The use of natural plant biostimulants is proposed as an innovative solution to address the challenges to sustainable agriculture, to ensure optimal nutrient uptake, crop yield, quality, and tolerance to abiotic stress. However, the process of selection and characterization of plant biostimulant matrices is complex and involves a series of rigorous(More)
Pompe disease (PD) is a recessive metabolic disorder characterized by acid α-glucosidase (GAA) deficiency, which results in lysosomal accumulation of glycogen in all tissues, especially in skeletal muscles. PD clinical course is mainly determined by the nature of the GAA mutations. Although ~400 distinct GAA sequence variations have been described, the(More)
Anthracnose, caused by Colletotrichum species is a highly limiting disease for the production of the tropical fruit tree crop, soursop (Annona muricata L.). In this study, 83 single-spore isolates of Colletotrichum were obtained from diseased soursoup tissues and subjected to a species complex-specific PCR assay. The isolates were identified as C.(More)
An island wide survey carried over 18 months across 79 tomato (Lycopersicum esculentum L.) plantations in 30 localities on 12 varieties revealed that symptoms related to phytoplasma-associated diseases are widespread in this species in Mauritius. Typical witches, broom and stunting and/or yellowing were observed in 74.6 % of fields visited. Phytoplasmas(More)
The thermoelectric cells are semiconductor devices used in mobile refrigeration, their behavior, it is to say, the way they respond to certain electrical stimulus, can be manipulated through control engineering techniques, the most popular, the Proportional-Integral-Derivative controller whose parameters are tuned by the Zigler-Nichols criterion; which in(More)
This study is the first to report a phytoplasma associated with machorreo in lulo. We detected the presence of a phytoplasma in association with machorreo in lulo, using phylogenetic analysis and homology with the sequence of the 16S rRNA region and the gene tRNA. We identified the phytoplasma as belonging to the 16Sr III group (Xdisease; 97% homology). For(More)
