Large numbers of vacuoles (10(6)-10(7)) have been isolated from Sorghum bicolor protoplasts and analyzed for the cyanogenic glucoside dhurrin. Leaves from light-grown seedlings were incubated for 4 hours in 1.5% cellulysin and 0.5% macerase to yield mesophyll protoplasts which then were recovered by centrifugation, quantitated by a hemocytometer, and assayed for cyanogenic glucosides. Mature va...

White clover is polymorphic for cyanogenesis, with both cyanogenic and acyanogenic plants occurring in nature. This chemical defense polymorphism is one of the longest-studied and best-documented examples of an adaptive polymorphism in plants. It is controlled by two independently segregating genes: Ac/ac controls the presence/absence of cyanogenic glucosides; and Li/li controls the presence/ab...

The forest understory is rich in fruit-bearing trees and shrubs. They include both native species invasive alien plant (IAPS). One of the most spreading IAPS black cherry (Prunus serotina E.). Problems with invasiveness P. well known many European countries. However, there are very few studies related to this IAPS. This article aims fill gap research on bioactive compounds fruits thus start a d...

For more than 420 million years, plants, insects and their predators have co-evolved based on a chemical arms race including deployment of refined chemical defence systems by each player. Cyanogenic glucosides are produced by numerous plants and by some specialized insects and serve an important role as defence compounds in these intimate interactions. Burnet moth larvae are able to sequester c...

This study aimed to determine iodine, selected goitrogens in some grains Sokoto. Related factors were measured clay, loamy, and sandy soils using standard methods reagents of analytical grade. Western zone (WZ) has highest iodine (29 ± 0.01 ppm), then Central Zone (CZ) (26 Eastern (EZ) had (24 ppm). Sandy soil pH (6.55 0.08), clay (5.02 0.06) lastly loamy (4.02 0.05). Organic matter was (7.3±1....
