DNA lesions occur with loss of viability in embryos of ageing rye seed
In dry seeds, fragmentation of nuclear DNA and activation of DNases occur in vivo during embryo senescence. This loss of DNA integrity could be the source of chromosomal aberrations and impairedExpand

Function of DNA synthesis and DNA repair in the survival of embryos during early germination and in dormancy
DNA synthesis following the addition of water to excised embryos of non-dormant rye and to embryos of non-dormant and dormant genetic lines of Avena fatua has been examined. All the samples exhibitExpand

Adaptation and impairment of DNA repair function in pollen of Betula verrucosa and seeds of Oenothera biennis from differently radionuclide-contaminated sites of Chernobyl.
BACKGROUND AND AIMS The plants that have remained in the contaminated areas around Chernobyl since 1986 encapsulate the effects of radiation. Such plants are chronically exposed to radionuclides thatExpand

Identification of a monoclonal antibody to abscission tissue that recognises xylose/fucose-containing N-linked oligosaccharides from higher plants
Monoclonal antibodies raised against extracts of the rachis abscission zone of Sambucus nigra L. were selected for high reactivity towards abscission-zone proteins. One antibody (YZ1/2.23) has beenExpand

Special publication Evidence for a non-ACC ethylene biosynthesis pathway in lower plants
Abstract A wide range of lower plants is shown to lack the ability to convert ACC into ethylene although they produce ethylene continuously at rates similar to those in higher plants. [ 14 C]-ACC hasExpand
