Photosynthetic Chlorophyll Pigments in Phaseolus vulgaris Treated with Mutagens

, 2022
Beans (Phaseolus vulgaris) are considered one of major leguminous plants. In addition, they are characterised by a high genetic and significant variability, appropriate for agricultural production.

Optimizing germination and cultivation of edible halophytes using effluents from an IMTA system

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Halophytes offer nature‐based solutions to food insecurity and soil degradation, while their integration into integrated multi‐trophic aquaculture (IMTA) systems promotes circular economy practices. This study aimed to optimize the germination and cultivation of edible halophytic species, namely Limbarda crithmoides, Suaeda vera and

Content of photosynthetic pigments in pepper in vitro cultures [PDF]

, 2004
Chlorophylls are some of the most important chelates in nature. They are capable of channelling the energy of sunlight into potential chemical energy through the process of photosynthesis. Photosynthesis is complex biological process which occurs in in

Spectroscopy of Photosynthetic Pigment-Protein Complex LHCII

Acta Physica Polonica A, 2012
Light-harvesting pigment-protein complex of photosystem II is the most abundant membrane protein in the biosphere, comprising more than half chlorophyll molecules. The protein plays a role of photosynthetic antenna, collecting solar radiation and transferring excitations towards the reaction centers, where electric charge separation takes place ...

The effect of light supplementation on the changes in outer and inner fruit quality of different Selenicereus spp. cultivars

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Selenicereus spp., belonging to the Cactaceae family, produces pitaya, a fruit recognized for its exotic appearance and rich phytochemical composition. In regions with shorter photoperiods, flowering and fruit development are limited, making light supplementation a promising strategy.

Dynamical simulation of the optical response of photosynthetic pigments

Physical Chemistry Chemical Physics, 2010
From time integration of the electron dynamics under a density functional tight binding Hamiltonian in the presence of external time varying electric fields, we obtain the absorption spectra of a series of chlorophylls and bacteriochlorophylls. We obtain good agreement with the observed experimental energies as well as with fully ab initio results in ...

Beyond a dual role: how Purpureocillium lilacinum reprograms citrus metabolism for integrated biocontrol and growth promotion

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Plants harbor complex microbial communities that are fundamental to their health and productivity. Among them, endophytic fungi such as Purpureocillium lilacinum establish mutualistic associations, offering dual benefits as plant growth promoters and biocontrol agents.

Support for a Photoprotective Function of Winter Leaf Reddening in Nitrogen-Deficient Individuals of Lonicera japonica

Molecules, 2014
Plants growing in high-light environments during winter often exhibit leaf reddening due to synthesis of anthocyanin pigments, which are thought to alleviate photooxidative stress associated with low-temperature photoinhibition through light attenuation ...
