Variability of nutrient transport and associated upper ocean primary production induced by Kuroshio meanders in the Enshu-nada Sea, Japan by Namazue Gaku, Uchiyama Yusuke, Zhang Xu, Masunaga Eiji

“…A prominent difference was found in nitrate transport processes between for a period when the Kuroshio took a meandering path and for a non-meandering period, leading to about 1.5 times higher surface primary production measured by chlorophyl-a concentration during the non-meandering period than during the meandering period. …”

Development of a TSR-based method for understanding structural relationships of cofactors and local environments in photosystem I by Lujun Luo, Tarikul I. Milon, Elijah K. Tandoh, Walter J. Galdamez, Andrei Y. Chistoserdov, Jianping Yu, Jan Kern, Yingchun Wang, Wu Xu

“…A comprehensive study was conducted, by taking advantage of the PS I 3D structures and the TSR-based algorithm, to answer three questions: (i) Are electron cofactors including P700, A-1 and A0, which are chemically identical chlorophylls, structurally different? (ii) There are two electron transfer chains (A and B branches) in PS I. …”

Photosynthetic Pigments with Potential for a Photosynthetic Antenna: A DFT Analysis by Jesús Francisco Monzón-Bensojo, Manuel A. Flores-Hidalgo, Diana Barraza-Jiménez

“…Geometrical and electronic properties of the main photosynthetic pigments in higher plants such as chlorophylls and xanthophylls were studied to find potential candidates that were able to participate in an eventual zeolite-dye artificial antenna. …”

Spectroscopic analysis (UV-VIS-NIR) for predictive modeling of macro and micronutrients in grapevine leaves by J.I. Manzano, M. Rodríguez-Febereiro, M. Fandiño, M. Vilanova, J.J. Cancela

“…The findings revealed that reflectances in the visible (VIS) region of the spectrum played a key role in predicting micronutrients like B, corresponding with photosynthetic pigments (chlorophylls and carotenoids). In contrast, reflectances in the near-infrared region (NIR) had a greater impact on macronutrient prediction, particularly for P and Mg, due to their stronger interaction with organic compounds. …”
