Citrus Genomics

International Journal of Plant Genomics, Volume 2008, Issue 1, 2008., 2008
Citrus is one of the most widespread fruit crops globally, with great economic and health value. It is among the most difficult plants to improve through traditional breeding approaches. Currently, there is risk of devastation by diseases threatening to limit production and future availability to the human population. As technologies rapidly advance in

Methionine Synthase Positively Regulates Plant Defence to Both RNA and DNA Viruses and Is Useful for Developing Broad‐Spectrum Antiviral Resistance in Crops

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant viruses frequently cause severe economic losses in worldwide crop production. Developing broad‐spectrum resistance is the most efficient approach for controlling plant viral diseases. In this work, we found that the 17K protein of barley yellow dwarf viruses (BYDVs), which has multiple functions in viral pathogenesis including acting as ...

Leprosy in blood donors

Tropical Medicine &International Health, Volume 30, Issue 9, Page 1018-1022, September 2025.
Abstract Objectives We investigated the prevalence of anti‐phenolic glycolipid‐I (PGL‐I) IgM antibodies among temporarily unfit blood donors at the Pará State Blood Bank (HEMOPA), located in the Amazon region of northern Brazil. Using an arbitrary high cutoff for optical density (OD ≥0.750) in ELISA, a subset of donors was invited for clinical ...
