Damage potential of Heterodera zeae to Zea mays as affected by edaphic factors

On a étudié les effets du nématode à kyste du maïs, #Heterodera zeae, sur la croissance et la récolte en grain du maïs, #Zea mays, en microparcelles pendant les années 1986-1990. Ces expériences ont été conduites en microparcelles contenant du sol à texture fine ou grossière, avec ou sans engrais minéraux, avec ou sans #H. zeae$. La croissance du maïs (poids sec) et la récolte de grain ont décru de 13 à 73$. L'effet de #H. zeae sur les plantes a été plus important dans le sol de texture grossière que dans le sol à texture fine. Les engrais n'ont pas diminué les effets de #H. zeae sur la croissance des plantes. Le nématode a plus endommagé les plantes de maïs pendant les périodes chaudes et sèches que pendant les périodes fraîches et humides. (Résumé d'auteur

A Coordinated Effort to Manage Soybean Rust in North America: A Success Story in Soybean Disease Monitoring

Existing crop monitoring programs determine the incidence and distribution of plant diseases and pathogens and assess the damage caused within a crop production region. These programs have traditionally used observed or predicted disease and pathogen data and environmental information to prescribe management practices that minimize crop loss (3,69). Monitoring programs are especially important for crops with broad geographic distribution or for diseases that can cause rapid and great economic losses. Successful monitoring programs have been developed for several plant diseases, including downy mildew of cucurbits, Fusarium head blight of wheat, potato late blight, and rusts of cereal crops (13,36,51,80)

PLBD: protein–ligand binding database of thermodynamic and kinetic intrinsic parameters

We introduce a protein–ligand binding database (PLBD) that presents thermodynamic and kinetic data of reversible protein interactions with small molecule compounds. The manually curated binding data are linked to protein–ligand crystal structures, enabling structure–thermodynamics correlations to be determined. The database contains over 5500 binding datasets of 556 sulfonamide compound interactions with the 12 catalytically active human carbonic anhydrase isozymes defined by fluorescent thermal shift assay, isothermal titration calorimetry, inhibition of enzymatic activity and surface plasmon resonance. In the PLBD, the intrinsic thermodynamic parameters of interactions are provided, which account for the binding-linked protonation reactions. In addition to the protein–ligand binding affinities, the database provides calorimetrically measured binding enthalpies, providing additional mechanistic understanding. The PLBD can be applied to investigations of protein–ligand recognition and could be integrated into small molecule drug design
