A Model Nutrition Control System in Potato Tissue Culture and Its Influence on Plant Elemental Composition.

Low or excessive soil fertility is a major constraint to potato production. The influence of each individual nutrient element on potato plants under field studies remains ambiguous due to the influence of environmental variations. Creating an in vitro model plant with deficient or excessive nutrient content will provide a more controlled study and allow for a better understanding of how the concentration of one element can affect the uptake of other elements.

Optimization of an isothermal recombinase polymerase amplification method for real-time detection of Potato virus Y O and N types in potato.

Potato virus Y (PVY) is a global challenge for potato production and the leading cause of seed crop downgrading and rejection for certification. Accurate and timely diagnosis is key to effective control of PVY. Here we optimized the isothermal recombinase polymerase amplification (RPA) for accurate detection of different PVY O and N types that were tested, present in different tissues of potato plants including tubers with a primer set that specifically targets the highly conserved pipo region within the viral genome.
