Effects of ageing on peroxidase activity and localization in radish (Raphanus sativus L.) seeds.

Peroxidase activity was assayed in crude extracts of integument, cotyledons and embryo axis of radish seeds, deteriorated under accelerated ageing conditions. Over five days of ageing, in which germination decreased from 100 to 52%, the enzyme activity in integument was higher than that in other seed parts, increasing in the first days of ageing and then decreasing sharply in extremely aged see...

An a-L-arabinofuranosidase/b-D-xylosidase from immature seeds of radish (Raphanus sativus L.)

The carbohydrate moieties of arabinogalactan proteins (AGPs) are essential for their physiological functions and undergo rapid turnover in vivo. Degradation of the carbohydrate moieties of AGPs seems to occur by concerted action of several glycosidases, among them a-L-arabinofuranosidase, b-Dgalactosidase, and b-D-glucuronidase. Here, a bifunctional a-L-arabinofuranosidase/b-D-xylosidase from i...

Radish (Raphanus sativus) and Diabetes

For more than three decades, various in vitro and in vivo studies have linked radishes with diabetes, though this link has not been discussed. This review systematically addresses and summarizes the effect of radishes on diabetes. We searched the Web of Science, PubMed, and EMBASE databases for English language articles from June 1987 through May 2017 using the key words "radish" and "diabetes,...

Analysis of two novel classes of plant antifungal proteins from radish (Raphanus sativus L.) seeds.

Two novel classes of antifungal proteins were isolated from radish seeds. The first class consists of two homologous proteins (Rs-AFP1 and Rs-AFP2) that were purified to homogeneity. They are highly basic oligomeric proteins composed of small (5-kDa) polypeptides that are rich in cysteine. Both Rs-AFPs have a broad antifungal spectrum and are among the most potent antifungal proteins hitherto c...

Transport, ultrastructural localization, and distribution of chemical forms of lead in radish (Raphanus sativus L.)

Lead (Pb), a ubiquitous but highly toxic heavy metal (HM), is harmful to human health through various pathways including by ingestion of contaminated vegetables. Radish is a worldwide root vegetable crop with significant health and nutritional benefits. However, little is known about Pb translocation and distribution within radish plants after its uptake by the roots. In this study, Pb stress w...
