A new phenolic compound, named 3-geranyl-2,5-dihydroxy-benzaldehyde (1), together with seven known chalone derivatives (2–8) has been isolated from the seeds of Celosia cristata L. Their chemical structures have been elucidated by spectroscopic analysis. All these compounds (1–8) were isolated from C. cristata for the

Arenicola cristata, a marine annelid, is a well-known and prized traditional Chinese medicine. However, the serine protease gene of A. cristata has not been cloned yet. In this study, a novel protease of A. cristata was cloned, sequenced, and expressed in Escherichia coli, and the functions of this recombinant protease were also investigated. The whole complementary DNA (cDNA) of this novel pro...

Studying the evolutionary dynamics of an alien species surviving and continuing to expand after several generations can provide fundamental information on the relevant features of clearly successful invasions. Here, we tackle this task by investigating the dynamics of the genetic diversity in invasive crested porcupine (Hystrix cristata) populations, introduced to Italy about 1500 years ago, wh...

A new genus, Stijlolidia , and two new species, Stylolidia pectinata n. sp. (type species) and Stijlolidii cristata n. sp., from Malaysia are described and illustrated. A key to the males of the known species is also included. The Oriental leafhoppers of the tribe Coehdiini are composed of five rather distinct genera, three of which are fairly large and have speciated over the entire region (Ni...

Two phenolic compounds (PCoumaric acid and α–Tocopherol), two flavonoidal compounds ( luetoline and 7-methoxy luetoline) and two iridoidal glycosides (barlerin and schanshiside methyl ester) have been isolated from leaves of Barleria cristata their structure were established by spectral analysis. This is the first report of occurrence of these compounds from Barleria cristata Linn plant. K. HEM...

formerly the turkmenian stone loach was the only member of the genus metaschistura based on osteological characters. but recently, it is placed in the genus paraschistura based on mtdna coi data. to provide a detailed description of the osteological characteristics of paraschistura cristata (berg 1898), ten specimens of p. cristata were collected from the hari river basin in iran and their oste...

An antiviral protein (25 kD) isolated from leaves of Celosia cristata (CCP 25) was tested for depurination study on ribosomal RNA from yeast. Ribosomal RNA yielded 360 nucleotide base fragment after treatment with CCP 25 indicating that CCP 25 was a ribosome inactivating protein. CCP 25 also inhibited translation of brome mosaic virus (BMV) and pokeweed mosaic virus (PMV) RNAs in rabbit reticul...

Karyotypic analyses have several applications in studies of chromosome organization, evolution, and cytotaxonomy. They are also essential to genome assembly projects. Here, we present for the first time karyotype description endangered species yellow cardinal, Gubernatrix cristata (Passeriformes, Thraupidae), using conventional staining with Giemsa 18S rDNA probes. This has 78 chromosomes, 12 p...
