Genome-wide identification of StMAPKKKs and functional characterization of StMAPKKK44 in regulating salt and drought tolerance in potato (Solanum tuberosum L.).

Journal of plant physiology | 2026-May-18

This study identifies 85 MAPKKK genes in potato (Solanum tuberosum) and characterizes the function of StMAPKKK44. Overexpression of StMAPKKK44 in potato plants enhances tolerance to salt and drought stress by improving antioxidant defense and osmotic balance. The findings suggest StMAPKKK44 is a promising target for breeding stress-resilient potato cultivars.

Integrating demographic characteristics, settling preference, and field investigation for resistance evaluation of four potato cultivars to Myzus persicae.

Pest management science | 2026-Jun-08

This study evaluates the resistance of four potato (Solanum tuberosum) cultivars to the aphid pest Myzus persicae using demographic life tables, settling preferences, and field trials. The results identify Evely Lucette as a highly susceptible host and Lucinda V7 as a relatively resistant cultivar. These findings provide valuable insights for breeding aphid-resistant potato cultivars and improving pest management strategies.

Effects of temperature on the life-history traits of Myzus persicae and its efficiency in transmitting potato virus Y (PVY) in potato crops.

PeerJ | 2026

This study investigates the impact of temperature on the life-history traits of the aphid Myzus persicae and its transmission efficiency of potato virus Y (PVY) in potato crops. The researchers found that temperature significantly affects aphid development and fecundity, with PVY transmission efficiency peaking at 20 °C. These findings are crucial for predicting PVY spread and developing localized management strategies to protect potato production.

Production of hydrolytic enzymes from crop waste for bioconversion of lignocellulosic biomass to ethanol.

3 Biotech | 2026-Jul

This study evaluates the use of potato peels as a carbon substrate for producing hydrolytic enzymes from a Bacillus species. The resulting enzyme mixture was successfully used to saccharify pretreated potato peel waste into glucose, which was then fermented to produce ethanol.
