Ab initio calculation of UV-Vis absorption spectra of a single molecule chlorophyll a: Comparison study between RHF/CIS, TDDFT, and semi-empirical methods [PDF]
ITB Journal of Science 44A (2), 79-98 (2012), 2011 Chlorophyll a is one the most abundant pigment on Earth that responsible for trapping the light energy to perform photosynthesis in green plants. This molecule is a metal-complex that consists of a porphyrin ring with high symmetry that acts as ligands with magnesium as the central ion. Chlorophyll a has been studied for many years from different point

Advanced Science, EarlyView.Tomato chlorosis virus (ToCV) infection induces production of neophytadiene, a volatile resulting from chlorophyll degradation that is highly attractive to whiteflies. OBP2, an odorant‐binding protein from insect vector B. tabaci, exhibits a strong binding affinity for neophytadiene.

Advanced Science, EarlyView.Salt stress endangers coastal cereal crops, requiring resilient crop solutions. This study employs machine learning (KANMB) to analyze multi‐omics data from halophyte Spartina alterniflora, revealing 226 salt‐stress biomarkers and linking them to tolerance pathways. The MYB gene SaMYB35 regulates flavonoid biosynthesis under salinity.

The Diverse Modes of Oxygen Reactivity in Life & Chemistry
ChemSusChem, Volume 15, Issue 24, December 20, 2022., 2022 Breath of life: Oxygen is the quintessential molecule of life on our planet. Three molecular oxygen species dominate natural and artificial oxygenation reactions: the singlet and triplet spin states of dioxygen and ozone. This Review summarizes key applications of these molecular oxygen species in biology, medicine, technologies, and laboratories ...

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

Manipulating the Light Systemic Signal HY5 Greatly Improve Fruit Quality in Tomato
Advanced Science, EarlyView.This study establishes that HY5, activated by low‐dose light, acts as a systemic signal to enhance tomato fruit quality by directly promoting carotenoid synthesis and sugar metabolism. These findings demonstrate HY5's mobility from leaves to fruits and its application potential through nighttime LED lighting, offering a practical strategy for crop ...

Evolution of Photosynthesis and Biospheric Oxygenation Contingent Upon Nitrogen Fixation? [PDF]
Int.J.Astrobiol. 4 (2005) 251-257, 2006 How photosynthesis by Precambrian cyanobacteria oxygenated Earth's biosphere remains incompletely understood. Here it is argued that the oxic transition, which took place between approximately 2.3 and 0.5 Gyr ago, required a great proliferation of cyanobacteria, and this in turn depended on their ability to fix nitrogen via the nitrogenase enzyme ...
