Two experiments determined effects of collection and preparation techniques on nutrient composition of masticate samples from esophageally fistulated cattle. In Exp. 1, 12 esophageally fistulated cattle were maintained on 2 precollection diets, high CP (24% CP; = 6) or low CP (7.7% CP; = 6), for 8 d. On d 9, the esophageal plug was removed, screen bottom bags were attached, and each cow was off...

Spraying tobacco plants with salicylic acid induces both the synthesis of 'pathogenesis-related' (PR) proteins and resistance to viruses that can induce necrotic lesions. We show that spraying Samsun NN tobacco with salicylic acid induced the production of PR-1 mRNAs and inhibited the systemic multiplication of alfalfa mosaic virus (A1MV) by 90%. Salicylic acid treatment also induced the synthe...

Alkaline salts (e.g., NaHCO3 and Na2CO3) causes more severe morphological and physiological damage to plants than neutral salts (e.g., NaCl and Na2SO4) due to differences in pH. The mechanism by which plants respond to alkali stress is not fully understood, especially in plants having symbotic relationships such as alfalfa (Medicago sativa L.). Therefore, a study was designed to evaluate the me...

Abstract Agricultural intensification is affecting the biological control of insect pests, an important component for sustainable crop production. To understand changing patterns abundance within agroecosystem, it necessary to disentangle trophic interactions between species, and metabarcoding excellent alternative show them. In Ebro Basin (NE Iberian Peninsula), agricultural landscapes are com...

Fragaria chiloensis latent virus (FClLV), a member of the genus Ilarvirus was first identified in the early 1990s. Double-stranded RNA was extracted from FClLV infected plants and cloned. The complete nucleotide sequence of the virus has been elucidated. RNA 1 encodes a protein with methyltransferase and helicase enzymatic motifs while RNA 2 encodes the viral RNA dependent RNA polymerase and an...
