  5. 13. Signalling between plants and microorganisms

    Author : Ulrika Troedsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; symbiosis; Chitinase; rhizobium; mycorrhiza; plant; glucanase; Biology; Biologi;

    Abstract : Plants and microbes can interact in several ways. Plants can be attacked by different types of pathogens like fungi, virus and bacteria, but can also form symbioses with fungi and bacteria. Certain common antimicrobial proteins are produced by the plants regardless of the type of microbial interaction with the plant. READ MORE

  6. 14. Cambro-Ordovician microorganisms: acritarchs and endoliths
