  1. 1. Defence and signalling in Potato-Phytophthora infestans interactions

    Author : Ashfaq Ali; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phytophthora infestans; Plant defence; hypersensitive response; resistance; susceptibility;

    Abstract : Potato is one of the major food crops and its yield is severely affected by late blight disease caused by Phytophthora infestans. P. infestans has the ability to manipulate plant defence signalling by secreting effector molecules causing so called effector triggered susceptibility. READ MORE

  2. 2. Gene silencing mechanisms in Phytophthora infestans

    Author : Vetukuri Ramesh; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The hemibiotrophic oomycete, Phytophthora infestans, causes late blight on potato and tomato. This destructive pathogen is well known for the rapidity with which it overcomes host resistance. This thesis focuses on the molecular basis of gene (RNA) silencing in P. infestans and the role it may have in its genome biology and pathogenesis. READ MORE

  3. 3. Size matters : RNA silencing processes in Phytophthora infestans

    Author : Anna Åsman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES;

    Abstract : Non-coding RNAs do not encode proteins but instead function through their own RNA sequence. These molecules range from several thousands of nucleotides (nt) in length down to around 20 nt. Specifically, small RNAs (sRNAs) have critical functions in eukaryotic cells, despite being only 20-30 nt long. READ MORE

  4. 4. Small RNAs in Phytophthora infestans and cross-talk with potato

    Author : Sultana Jahan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Small RNAs (sRNAs) are small non-coding RNAs usually ranging in size 20-30 nt. They are playing important roles in plant-pathogen interactions. This thesis aimed at studying the sRNA populations in potato and Phytophthora infestans and their role in the potato-P. infestans interaction. READ MORE

  5. 5. How sexual reproduction affects the population biology of Phytophthora infestans

    Author : Lina Sjöholm; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Phytophthora infestans is a rapidly evolving and highly adaptable pathogen. It is the cause of late blight, one of the most devastating diseases in potato production. Depending on whether both mating types are present or not, P. infestans can undergo both asexual and sexual reproduction. READ MORE
