MicroRNA156 is an evolutionarily highly conserved plant micro-RNA (miRNA) that controls an age-dependent flowering pathway. miR156 and its target SQUAMOSA PROMOTER BINDING PROTEIN-LIKE (SPL) genes regulate anthocyanin accumulation in plants, but it is unknown whether this process is affected by light. Red Chinese sand pear (Pyrus pyrifolia) fruits exhibit a unique coloration pattern in response...

Introduction: To establish the pharmacognostical and phytochemical standardization parameters of Pyrus pashia fruits in order to ensure quality and safety of this traditionally acclaimed medicinal tree. Methods: The fresh fruits of P. pashia were collected and dried. Fruit was subjected to various pharmacognostical investigations, Extraction procedures, and preliminary phytochemical screening, ...

Seed dispersal by animals is a key interaction, with effects on the population ecology and evolution of many plant lineages. Despite the fact that infrequent seed dispersers can potentially provide important services to plant populations, little attention has been paid so far to scarce mutualists. We assessed different aspects of quantity and quality of seed dispersal from fruit removal to seed...

Polymerase chain reaction (PCR)-based detection strategies were adopted to examine the etiology and vectorship of pear decline in Taiwan (PDTW). 16S rDNA sequences were amplified from total DNAs prepared from PDTW-affected pear trees Pyrus serotina Rehd. cv. Hengshan and pear psyllid Cacopsylla chinensis using PCR. According to the sequence analyses, C. chinensis carried phytoplasmas of two 16S...

The sequence of events which occurs during the ripening of the Passe-Crassane pear fruit have been previously studied. In this work, we have investigated the ripening of another climacteric fruit (Pyrus malus L. cv Golden Delicious) and of a nonclimacteric fruit (Prunus avium L. cv Bigarreau Napoléon). We show that both climacteric fruits exhibit the same preclimacteric sequence of events. Diff...

background identification of novel pathogenic bacteria always has a crucial role in clinical microbiology to defeat uncontrolled diseases. objectives sample preparation platform has been developed for rapid and simple detection of infectious organisms from the point of care diagnostics and molecular manipulation by using three novel genomic dna isolation protocols. materials and methods most of...
