Apoptosis in developing anthers and the role of ABA in this process during androgenesis in Hordeum vulgare L

Intra-nucleosomal cleavage of DNA into fragments of about 200 bp was demonstrated to occur in developing anthers, in which microspores had developed into the mid-late to late uni-nucleate stage in situ, i.e. at the verge of mitosis.
