RATIONALE Genome-wide associat10n studies (GW AS) are an efficient approach to dissect the genetic architecture of complex traits. Lipids, including the diterpenes cafestol and kahweol, are key compounds that contribute to the quality of coffee beverages. A genome-wide association study was performed to identify genomic regions associated with lipi...
Centella asiaticais aherbal plant generally used for its curative properties. Two foliar morphotypes were recently identified in Madagascar: a reniform tetraploid (2n = 4x = 36) in the Center and the East of the island and a round diploid (2n = 2x = 18) in the West. The objective of this study was to evaluate the nutritional properties of these two...
Arabica coffee is a main economic crop throughout Central and South American highlands, where millions of people get primary outcome. Last coffee leaf rust (CLR) epidemic event in 2011, which impacted 53% of the coffee region areas, provoking losses up to USD 500 million, remembered the high vulnerability of the coffee sector to the fungus Hemileia...
In Kenya coffee quality is determined by the grade proportions and beverage quality which are influenced by various factors including variety, shade and altitude. The objective was to characterize the quality of coffee produced by farmers producing traditional varieties and Ruiru 11 under shade or under full sun in Muranga County. One hundred and f...
Les tourteaux de colza et de tournesol, principalement utilisés en alimentation animale pour leur forte teneur en protéines, représentent des sources d'acides phénoliques aux propriétés antioxydantes et bioacives variées mais peu valorisées à ce jour. Par ailleurs, les procédés de séparation de ces composés sont basés sur des extractions par solvan...
RATIONALE Flowering is a particularly important trait in coffee (Cofjea arabica L.). It determines the coffee yield, quality and production costs. It defines the critical period of highest demand for nutrients, water and pest and disease control. During this development phase, the plant is most susceptible to extreme climatic conditions. Factors su...
METHODS We monitored coffee water use (I day- 1) and certain microclimate parameters (rainfall, temperature, relative humidity, radiation and soil moisture) during one year (March 2015 - April 2016) in coffeeopen systems and coffee-shade systems at Mt. Elgon, Uganda. RESULTS Coffee daily water use per plant (1 .2 ± 0.64 1 d-1) and coffee transpirat...
Plant functional traits directly affect ecosystem functions. At the species level, trait combinations depend on trade-offs representing different ecological strategies, but at the community level trait combinations are expected to be decoupled from these trade-offs because different strategies can facilitate co-existence within communities. A key q...
The threat of bacterial resistance to antibiotics has created an urgent need to develop new antimicrobials. The aim of this study was to characterize the chemical diversity of Litsea cubeba leaf essential oil (EO) and its impacts on the antibacterial activity against pathogenic bacteria. Essential oils collected from seven provinces in North Vietna...
The climate warming implies an increase of stress of plants (drought and torrential rainfall). The understanding of plant behavior, in this context, takes a major importance and sap flow measurement in plants remains a key issue for plant understanding. Magnetic Resonance Imaging (MRI) which is well known to be a powerful tool to access water quant...
