Xerophyta viscosa Baker (family Velloziaceae) is a desiccation tolerant plant which survives extremes of dehydration down to 5% relative water content (RWC) and resumes full physiological activity within 80h of rehydration. The nuclear proteome of Xerophyta viscosa and its response to dehydration at 35% RWC as compared to fully hydrated plants was analysed… (More)
Provides a first comprehensive review of integrated physiological and molecular aspects of desiccation tolerance Xerophyta viscosa . A synopsis of biotechnological studies being undertaken to improve drought tolerance in maize is given. Xerophyta viscosa (Baker) is a monocotyledonous resurrection plant from the family Vellociacea that occurs in… (More)
The plant nucleus is an important subcellular organelle but the isolation of pure and enriched nuclei from plants and subsequent extraction of nuclear proteins for proteomic studies is challenging. Here, we present protocols for nuclei isolation and nuclear protein extraction from the resurrection plant, Xerophyta viscosa, and show optimization and… (More)
The primary structure of three major cationic peptides from porcine neutrophils has been determined. The sequencing was made by the combined use of electrospray ionization mass spectrometry and Edman degradation. The determined sequences unambiguously show that these peptides can not be considered as defensins.
