Blue Light Receptor PHR2‐Mediated Spectrum Antiviral Immunity
Advanced Science, EarlyView.Blue light suppresses RBSDV through the blue‐light receptor ZmPHR2, which interacts with ZmISP in chloroplasts to trigger ROS burst and antiviral defense. The viral effector P6 enhances ZmPHR2–ZmISP interaction, alters their distribution, and suppresses ROS.

Applied Economic Perspectives and Policy, EarlyView.ABSTRACT We conducted two framed field economic experiments with citrus farmers in Florida, United States and soybean farmers in Argentina to investigate their willingness to coordinate pest and weed management efforts. Despite the contrast between these two agricultural contexts, we find striking behavioral commonalities.

Panicle inclination influences pollination stability of rice (Oryza sativa L.)
Plant Production Science, 2020 Rice pollination occurs when pollen grains fall by gravity from the anther onto the stigma and has been thought to be assured under suitable conditions. However, the position of the stigma relative to the anther pores may affect pollination.

American Journal of Agricultural Economics, EarlyView.Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market
