Comparative analysis of expressed sequence tags from Flammulina velutipes at different developmental stages.

Flammulina velutipes is a popular edible basidiomycete mushroom found in East Asia and is commonly known as winter mushroom. Mushroom development showing dramatic morphological changes by different environmental factors is scientifically and commercially interesting. To create a genetic database and isolate genes regulated during mushroom development, cDNA libraries were constructed from three developmental stages of mycelium, primordium, and fruit body in F.

Isolation of Genes Specifically Expressed in Different Developmental Stages of Pleurotus ostreatus Using Macroarray Analysis.

The oyster mushroom (Pleurotus ostreatus) is one of the most important edible mushrooms worldwide. The mechanism of P. ostreatus fruiting body development has been of interest both for the basic understanding of the phenotypic change of the mycelium-fruiting body and to improve breeding of the mushrooms.

Isolation of genes expressed during the developmental stages of the oyster mushroom, Pleurotus ostreatus, using expressed sequence tags.

In order to isolate and identify the developmentally regulated genes during fruiting body development, cDNA libraries were constructed from eight developmental stages of the Oyster mushroom, Pleurotus ostreatus. From these libraries, 11 761 expressed sequence tags (PoESTs) were generated. Of these, 4060 different genes (PoUnigenes) were identified, representing 34.

Cloning and developmental expression of a metzincin family metalloprotease cDNA from oyster mushroom Pleurotus ostreatus.

A cDNA clone, PoMTP, encoding a putative metzincin family metalloprotease was isolated from the expressed sequence tags of a basidiomycete Pleurotus ostreatus. The 5'-end sequence of PoMTP was determined by the 5'-RACE method. Full-length cDNA sequence (1140 bp) of PoMTP contained a 870 bp open reading frame encoding a protein product of 290 amino acids in addition to a 99 bp of 5'-untranslated sequence and a 171 bp of 3'-untranslated sequence with a poly(A) tail.

Differential expression profiling of the proteomes and their mRNAs in porcine white and red skeletal muscles.

Skeletal muscle is an heterogeneous tissue with various biochemical and physical properties of several fiber types. In this study, we carried out the comparative study of protein expression patterns in white and red muscles using two-dimensional gel electrophoresis (2-DE). From more than 500 protein spots detected on each 2-DE gel, we screened five proteins that were differentially expressed between white and red muscles.
