• Integrative Modelling for understanding GenesxEnvironmentxProcesses interactions in the determinims of fruit and leaf growth
  13 April 2021, by Zhou

  Understanding and predicting variations in the growth of sink and source organs as a function of the environment is a challenge for biologists. FruitLeafModel proposes to combine experimentation and modelling to understand the impact of water deficit (HD) on fruit and leaf growth in tomato, through an analysis of the main processes involved. The project is based on the Virtual Fruit Model (PSH Avignon) and the tools developed on the phenotyping (LEPSE Montpellier) and imaging (BFP Bordeaux) (...)

• 3D virtual fruit: application to fruit growth and quality control
  3 May 2021

  • Since water and carbon are delivered through a complex vasculature system and its pattern depends on fruit shape and the arrangement of tissues (Fig.1), the architecture of a fruit has an impact on fruit quality. .
  • For example, in causing physiological disorders appearing on the apical end [1]. .
  • Most current fruit models focus on investigating the physiological processes governing fruit quality development without considering fruit architecture [2]. .
  • Existing methods for generating (...)

• ’Characterisation of the nutritional composition of Ghanaian fruits and vegetables and the impact of cooking methods’
  3 May 2021

  ’Micronutrient deficiencies are widespread in Ghana, linked to diets that are predominantly starch-based with less fruits and vegetables. Ghana produces a variety of fruit and vegetables, but little is known about these products and their nutritional importance. The aim of the project was therefore to measure the micronutrient contents in various fruit and vegetables, in order to identify the best sources and have convincing data for their recommendation, as well as evaluate the impact of (...)

• A tool for designing sustainable production systems - the case of the peach/brown food pair Modeling of Peach-Monilia ideotypes
  3 May 2021

  The peach-brown rot couple is a complex system under the triple influence of the genotype (fungus and host), the environment and cultural practices. Studying this system could lead to a reduction of fungicide use and thus to ecological, economical and health benefits. With the support of Agropolis Fondation, an interdisciplinary team of scientists from INRA conducted a study to illustrate how a model-based design approach could be used as decision making tool in handling such a complex (...)

• Development of a non-destructive methodology for phenotyping mandarins by infrared spectroscopy to assist in the study of phenotypic variability in response to water stress and in varietal selection
  3 May 2021

  This study had as main objective the nondestructive phenotyping of mandarins quality by near infrared spectroscopy. The specific objectives of the project were: 1) Define the protocol for measuring spectral reflectance of whole mandarins using a spectrometer ultra-portable Phazir 1018 (Polychromix, Thermo Fisher Scientific, 2 Radcliff Road, Tewksbury, MA 01876, USA ) 2) Develop calibration equations for Brix and acidity contents. In a first step, a precise measurement protocol was (...)

• AWARD - Improvement of microbiological and biochemical characteristics of pineapple juice from Rwanda
  3 May 2021

  Pineapple fruit is a major horticulture crop in Rwanda. Recently, the government of Rwanda has put much effort into the cultivation of pineapple fruits. This because the fruit can be grown on all agro ecological zones of Rwanda and can resist to many fruit diseases. Thus, the increase in its production targets the export market of the pineapple fruit and its products and thus the improvement of the country’s economy. To respond to the government call, about 27 small scale pineapple (...)

• ’Connecting the biologies of rice disease resistance, drought tolerance and flowering times’
  3 May 2021

  ’Drought tolerance, disease resistance and flowering time are three major traits in crops that are biologically connected. However the molecular connection nodes linking them together are poorly understood. The Riceconnections projects aims at identifying such nodes in the model system involving rice using three approaches: phenotyping under laboratory and field conditions rice mutants, gene expression analysis under combined biological conditions and identifying proteins that are connecting (...)

• Combined (eco)-physiological approach and 3D modelling to understand and analyse the role of the cuticle in the growth and quality of fleshy fruits
  29 April 2022

  The cuticle has a major role in controlling water loss, micro- and macro-cracking of the fruit, its shelf life, and its resistance to biotic and abiotic stresses. However, the interactions between the mechanical properties of the tissues and the regulation of water and carbon fluxes during fruit development, as well as their consequences on the final size and composition of the fruit, have been little (...)
