Symbiont diversity is not involved in depth acclimation in the Mediterranean sea whip Eunicella singularis [PDF]

open access: yes, 2011
In symbiotic cnidarians, acclimation to depth and lower irradiance can involve physiological changes in the photosynthetic dinoflagellate endosymbiont, such as increased chlorophyll content, or qualitative modifications in the symbiont population in ...

Chlorophyll breakdown and chlorophyll catabolites in leaves and fruit [PDF]

open access: yesPhotochemical & Photobiological Sciences, 2008
Chlorophyll metabolism probably is the most visible manifestation of life. Total annual turnover of chlorophyll has been estimated to involve more than 1000 million tons. Surprisingly, chlorophyll catabolism has remained an enigma until less than twenty years ago, when a colorless chlorophyll catabolite from senescent plant leaves was identified and ...

Excitation Energy Transfer between Porphyrin Dyes on a Clay Surface: A Study Employing Multifidelity Machine Learning

open access: yesAdvanced Theory and Simulations, EarlyView.
Inspired by natural light‐harvesting systems, this study computationally investigates a synthetic antenna by arranging cationic free‐base porphyrin molecules on an anionic clay surface. Using a multiscale quantum mechanics/molecular mechanics (QM/MM) approach combined with a multifidelity machine learning method, excitation energies are predicted ...

A Study on the Cell Layer Patterns of a Citrus Periclinal Chimera Reveals β‐Cryptoxanthin Regulation in Citrus Fruits

open access: yesAdvanced Science, EarlyView.
Researchers have identified a citrus chimera with distinctive tissue origins and carotenoid profiles. It is discovered that fruit tissues develop from all three cell layers but in different proportions. A key transcription factor, MYB107, regulates β‐cryptoxanthin production by directly activating carotenoid biosynthesis genes, explaining why some ...

Responses of tomato (Solanum lycopersicum L.) plants to iron deficiency in the root zone [PDF]

open access: yes, 2019
Iron deficiency induces a yellowing in the aerial part of plants, known as iron chlorosis, and reduces the growth, yield, and quality of the fruits. Understanding plant response to iron deficiency is essential for agronomic management. This study decoded

Chloroplast Fibrillin‐Mediated α‐Tocopherol Biosynthesis Impaired by a Virus to Enhance Infection and to Improve Drought Tolerance

open access: yesAdvanced Science, EarlyView.
ToCV‐encoded p22 targets chloroplast plastoglobules (PGs) via directly binding PG structural protein FBN1.1, reducing the size of PG and inhibiting α‐tocopherol biosynthesis via competing with tocopherol cyclase (VTE1). Consequently, the elevated chloroplast ROS not only creates a suitable cellular environment for efficient ToCV infection but also ...

Estimating Oceanic Export Production based on 3D coupled physical-biogeochemical modelling [PDF]

open access: yes, 2013
The study addresses various aspects of model-based estimating the oceanic primary production. In particular, we consider existent interpretations of the export fluxes; influence of implied conversions between modelled chlorophyll and biomass, expressed ...
