  1. 1. Spray Induced Gene Silencing in Phytophthora infestans : investigating exogenous dsRNA application for the control of potato late blight

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Poorva Sundararajan; [2024]
    Keywords : Phytophthora infestans; RNAi; potato late blight; gene silencing; SIGS;

    Abstract : Phytophthora infestans is an oomycete pathogen and the causal agent of late blight disease in potato and tomato. Even today, it causes massive loss to crop and economy worldwide. Current disease control strategies include breeding for resistance and extensive fungicide spray. READ MORE

  3. 2. The role of P25 interacting transcriptional regulator VIP1 in activation of transcription.

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Asma Kanon Hashi; [2022]
    Keywords : Rhizomania; BNYVV; expression clones; virulence factor P25; transcription; transient gene expression; VIP1 plant protein;

    Abstract : Rhizomania, caused by beet necrotic yellow vein virus (BNYVV), has been considered as an economically important disease around the world because of the extreme reduction in sugar beet yield and sugar content in affected plants. The spread of rhizomania all over the world, including the emergence of resistance- breaking virus isolates, have been become a major concern for the plant pathologists and plant breeders aiming at improving sugar beet resistance to   BNYVV as well as better understanding sugar beet-virus interactions during disease development.

    Abstract : Det finns flera sjukdomar som påverkar spenat (Spinacia oleracea). Sjukdomarna sänker skörden och försämras kvaliteten av produkten. Dessutom vill konsumenter inte ha angripna plantor som inte ser bra ut. I Sverige är den allvarligaste sjukdomen spenatbladmögel, orsa-kat av Peronospora effuosa f. READ MORE

  5. 4. Virtual weather data for apple scab monitoring and management

    University essay from SLU/Dept. of Plant Protection Biology

    Author : Philip Zandelin; [2021]
    Keywords : Apple scab; virtual weather stations; grid-data; decision support system; RIMpro; integrated pest management; leaf wetness;

    Abstract : Decision support systems can be used to monitor disease development of apple scab. Decision support systems require weather data to function, which in Sweden is currently provided by conventional weather stations. READ MORE

  6. 5. Virus yellows in sugar beets in Sweden and Europe

    University essay from SLU/Dept. Of Plant Biology
