Fine structures of the zona radiata in zebrafish, Danio rerio, is examined and compared. The zona radiata (called as zona pellucid in mammals), is a porous structure located between oolemma and follicle cell epithelium in fish, has various functions. The zona radiata is an inner connection surface that regulates essential transition from follicle cells to oocytes and from oocytes to follicular ...

Mungbean (Vigna radiata (L.) Wilczek) is having a desirable characters like short duration, high protein, less anti nutritional factors, nitrogen fixing capacity, suitable for inter cropping, making many kinds of foods for higher human consumption and cosmetics products and some of the undesirable characters like low yield, low test weight.The aim of the study is to check crossabil;ity of Vigna...

Tests evaluating the host range of Tamarixia radiata (Waterson) (Hymenoptera: Eulophidae), a parasitoid of the pestiferous Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), sourced from the Punjab of Pakistan, were conducted in quarantine at the University of California, Riverside, CA. Seven nontarget psyllid species (Þve native and two selfintroduced species) representing ...

BACKGROUND Before human MII oocytes are vitrified they are usually denuded from their cumulus cells. In this study we wanted to investigate the effects of an intact corona radiata on the vitrification and fertilization of human oocytes. METHODS The study comprised two different parts. In Part 1, 36 MII stage oocytes, from 6 patients, were randomly assigned into a control group, a group of vit...

Lycoris radiata is an important medicinal and ornamental plant of China. In the present study, somatic chromosome counts and karyotype analyses, which are important aspects of plant phylogeny and evolution, were performed in 466 individuals from 25 L. radiata populations by root tip squash method. Chromosome counts revealed that 10 populations were diploid (2n = 2x = 22) and 15 were triploid (2...

Sphaeropsis sapinea is an endophyte and latent pathogen of pines, assumedly introduced to the Southern Hemisphere along with its host. There are at least three recognised forms of S. sapinea that differ from each other morphologically and can also be separated based on molecular characteristics. Pinus radiata is a native to California but has been used extensively for afforestation in the South...

Present study reports the antioxidant activities of methanolic extracts of Actiniopteris radiata and Equisetum ramosissimum. The analyses carried out were DPPH radical scavenging, ABTS·+, reducing power, and ferrous ion chelating tests. From the analyses, Actiniopteris radiata and Equisetum ramosissimum, were found to have potent antioxidant activity against DPPH with the IC50 value of 93.48 an...

Tamarixia radiata (Waterston, 1922) is the main parasitoid of Diaphorina citri (Kuwayama, 1907), and has been used in classical biological control programs in several countries. The current study investigated the biology and determined the fertility life table of T. radiata in different temperatures, to obtain information to support the establishment of a biological control program for D. citri...
