Barnyardgrass (Echinochloa crus-galli) is one of the most pernicious and problematic weeds in worldwide agriculture. The objective of this review is to highlight the morphology and habitats of this weed, and to present comprehensive information of the allelochemical constituents and pharmacological effects as well as its allelopathic interaction with rice (Oryza sativa L.) based on 115 worldwide literary resources reported over the last 40 years.

In this report, we examine the unsteady Stokes equations with nonhomogeneous boundary conditions. As an application of a Carleman estimate, we first establish log type stabilities for the solution of the equations from either an interior measurement of the velocity, or a boundary observation depending on the trace of the velocity and of the Cauchy stress tensor measurements on a part of the boundary.

Saccharomyces cerevisiaehas been used as a model system to characterize the effect of cytochromebmutations found in fungal and oomycete plant pathogens resistant to Qo inhibitors (QoIs), including the strobilurins, now widely employed in agriculture to control such diseases. Specific residues in the Qosite of yeast cytochromebwere modified to obtain four new forms mimicking the Qobinding site of Erysiphe graminis, Venturia inaequalis, Sphaerotheca fuligi-neaandPhytophthoramegasperma.

Intraluminall-phenylalanine (Phe) stimulates cholecystokinin (CCK) secre-tion in vivo andin vitro. However, the cellular mechanism by which CCK-producing enteroendocrine cells sense Phe is unknown. The calcium-sensing receptor (CaR) can sense amino acids, and is expressed in the gastrointesti-nal tract.

PUBLIC GOODS, PRIVATE INCENTIVES, AND AGRICULTURAL R&D: PRODUCTIVITY AND POVERTY IN DEVELOPING COUNTRY AGRICULTURE Like Baker, McMillan, and Reuben (2002), I identify parental valuations by the location of clusters of high income families: If parental preferences over communities depend exclusively on the effectiveness of the local schools, the most desirable—and therefore wealthiest—communities are necessarily those with the most effective schools.

REVIEW ARTICLE Hanna Willander1,2, EriThe BRICHOS domain was initially defined from sequence alignments of the Bri protein associated with familial dementia, chondromodulin associ-ated with chondrosarcoma and surfactant protein C precursor (proSP-C) associated with respiratory distress syndrome and interstitial lung disease (ILD). Today BRICHOS has been found in 12 protein families.

Microbial biomass formation on root surfaces can be measured in plants growing in solution with or without an inert solid support. Carbon flow to the biomass can be measured by growing plants in solution or soil on a continuous source of 14C02 and the expected biomass formation predicted. The lack of correlation between measured and predicted biomass can be explained by oligotrophic growth of the micro-organisms.

Producers of dragon fruit in Vietnam have seen prices for their fruit decline by about 60% since 2000 which can be attributed, in part, to their dependence on local and nearby exports. There are about 10 major exporters in Vietnam but a significant portion of the total production is sourced from many small-holder growers. During the previous dragon fruit GAP project 037/04VIE, growers were evaluated through a benchmarking study to determine the status of the dragon fruit producers against the standards required by high value export markets....

Lack of knowledge and understanding at the scientific, extension and farmer levels is the primary limitation to the effective management of Phytophthora diseases in Vietnam. The objectives of this project are to extend sustainable and effective disease control and management recommendations to a range of horticultural crops throughout Vietnam to reduce crop losses due to Phytophthora and to improve farmer incomes.
