Spatial-Temporal Variability of Chlorophyll-a Concentration in Cenderawasih Bay and Surrounding Waters

Journal of Applied Geospatial Information, 2020
Chlorophyll-a is one of the parameters determining the primary productivity of water. In the fisheries sector, information on chlorophyll-a concentration in marine waters is very important for the prediction of fishing grounds. This study aims to analyze

River Streamflow, Remotely Sensed Water Quality, and Benthic Composition of Previously Undescribed Nearshore Coral Reefs in Northern Puerto Rico

Frontiers in Marine Science, 2021
Land-based sediment stress represents a threat to many coral reefs in Puerto Rico primarily as a result of unrestricted land cover/land use changes and poor best management practices.

Excitated state properties of 20-chloro-chlorophyll a [PDF]

, 1990
The excited-state and lasing properties of 20-chloro-chlorophyll a in ether solution were compared to those of chlorophyll a. Desactivation parameters and cross-sections were obtained from non-linear absorption spectroscopy in combination with a physico ...

The lack of plastidal transit sequence cannot override the targeting capacity of Bradyrhizobium japonicum δ-aminolevulinic acid synthase in transgenic rice

Biologia Plantarum, 2010
The δ-aminolevulinic acid synthase (ALA-S) is an enzyme which catalyzes the synthesis of δ-aminolevulinic acid (ALA). The Bradyrhizobium japonicum ALA-S coding sequence lacking plastidal transit sequence was introduced into the rice genome (C line).

Overexpression of cytoplasmic Solanum tuberosum Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) gene improves PSII efficiency and alleviates salinity stress in Arabidopsis.

Journal of Plant Interactions, 2021
In this study, transgenic Arabidopsis lines expressing a potato gene (D43), encoding Glyceraldehyde 3-phosphate dehydrogenase, were studied. The D43 plants exhibited improved morphological parameters and accumulation of photosynthetic pigments compared ...

Offshore wind farms changed the spatial distribution of chlorophyll-a on the sea surface

Frontiers in Marine Science, 2022
Offshore wind farms (OWFs) have developed rapidly in recent years. However, it is difficult to accurately evaluate their impact on marine ecosystems and the marine environment due to the complexity of marine dynamic monitoring and various marine ...
