    Union Catalogue of Agricultural Libraries in the Netherlands

    The WUR Library Catalogue contains bibliographic data on books and periodicals held by the libraries of Wageningen University and Research Centre and some 15 associated libraries. Holding data are added to each record.

    Subjects covered include Agrotechnology, Food and Food Production, Plant and Animal Sciences, Soil Science, Geo-information, Landscape and Spatial Planning, Water and Climate, Ecosystem Studies, Economics and Society.

    The joint collections of the participating libraries cover a substantial part of the internationally available scientific literature in these disciplines.

    As far as Dutch scientific literature in these fields is concerned, coverage can be considered near 100%, including much of the so-called "grey literature".

    All titles are entered in their original language. Keywords are added to facilitate subject searching.

    The database is updated every day and now contains over 830.000 records.

γrays, X rays, fast neutrons and ethyl methanesulfonate (EMS) were used for inducing mutations at the self-incompatibility locus of Nicotiana alata.

Chronic gamma irradiation and EMS treatment neither induced selfcompatibility mutations nor led to changes from one S allele to another. X rays and fast neutrons induced many self-compatibility mutations, but did not generate new self-incompatibility alleles.

Triploid individuals were male sterile.

Tri(S)allelic aneuploid plants were self-incompatible because heterogenic di(S)allelic pollen grains are not functional.

Self-compatibility in pollen-part mutants with and without a centric fragment was explained by complementation of the mutant S allele by a fragment or duplication. Deviations of expected segregation ratios were explained by lethality of S homozygotes.

It was shown that the longest unsatellited acrocentric chromosome is the S-bearing chromosome.

To support researchers to publish their research Open Access, deals have been negotiated with various publishers. Depending on the deal, a discount is provided for the author on the Article Processing Charges that need to be paid by the author to publish an article Open Access. A discount of 100% means that (after approval) the author does not have to pay Article Processing Charges.

For the approval of an Open Access deal for an article, the corresponding author of this article must be affiliated with Wageningen University & Research.
