Quantifying source–sink relationships in leaf-color modified rice genotypes during grain filling

引用

Journal of Integrative Agriculture 2024年第9期 2923-2940页

作者： Zhenxiang Zhou paul C.Struik Junfei Gu Peter E.L.van der Putten Zhiqin Wang Jianchang Yang Xinyou Yin Centre for Crop Systems Analysis Department of Plant SciencesWageningen University&Research College of Agriculture Yangzhou University

Leaf-color modification can affect canopy photosynthesis, with potential effects on rice yield and yield components. Modulating source–sink relationships through crop management is often used to improve crop productivity. This study investigated whether and how modifying leaf color alters source–sink relationships and whether current crop cultivation practices remain applicable for leaf-color modified genotypes. Periodically collected data of total biomass and nitrogen(N) accumulation in rice genotypes of four genetic backgrounds and their leaf-color modified variants(greener or yellower) were analyzed, using a recently established modelling method to quantify the source–sink(im)balance during grain filling. Among all leaf-color variants, only one yellower-leaf variant showed a higher source capacity than its normal genotype. This was associated with greater post-flowering N-uptake that prolonged the functional leaf-N duration, and this greater post-flowering N-uptake was possible because of reduced preflowering N-uptake. A density experiment showed that current management practices(insufficient planting density accompanied by abundant N application) are unsuitable for the yellower-leaf genotype, ultimately limiting its yield potential. Leaf-color modification affects source–sink relationships by regulating the N trade-off between preand post-flowering uptake, as well as N translocation between source and sink organs. To best exploit leaf-color modification for improving crop productivity, adjustments of crop management practices are required.

Cosmetic or Dietary Vegetable Oils Sampled in the Cameroonian Market May Not Expose Consumers to Lipid Oxidation Products Generating Oxidative Stress and Inflammation

引用

American Journal of Plant Sciences 2024年第3期15卷 193-202页

作者： Ferdinand Kouoh Elombo Erika van Damme Clara Delepine David Depraetere Ludovic Chaveriat paul Lunga Keilah Nico Fréderic Njayou Patrick Martin Laboratory of Toxicology and Pharmacology Department of Biochemistry Faculty of Sciences University of Yaound&#233 I Yaound&#233 Cameroon Dé partement de Chimie IUT B&#233thune Universit&#233 d&#8217Artois B&#233thune France Unité Transformations & Agroressources (ULR7519) Universit&#232 d&#8217Artois-UniLaSalle Bethune France

Vegetable oils are a source of energy, essential fatty acids, antioxidants and fat-soluble vitamins useful for human health care and development. These oils also contribute to organoleptic quality of their products’ derivatives. However, their chemical and physical properties can be modified by the mode of their extraction, storage and distribution. These modifications might negatively affect the nutritional quality of the oils. The goals of this study were to: sample different vegetable oils for cosmetic or dietary use marketed in Cameroon, and verify purity and oxidation states of each kind of oil through determination of its acidity, iodine, peroxide, saponification, refractive indexes and the conformity of the labeling. The carotene content, the level of polar components and specific absorbance were also determined. As the result, six oils namely palm, palm kernel, coconut, black cumin, peanut and shea butter were collected. Apart from labeling, chemicals and physicals parameters analyzed were generally in accordance with the Cameroonian and Codex Alimentarius standard. This study suggests that vegetable oils sampled in the Cameroonian market may not expose consumers to lipid oxidation products generating pathological oxidative stress and inflammation. However, efforts in application of existing standard need to be done as far as labeling are concerned.
