Towards a more accurate future for chlorophyll a and b determinations: the inaccuracies of Daniel Arnon’s assay
TLDR
A summary not only of an accurate assay of chlorophylls in aqueous 80% acetone but also of a long-known method to correct the data obtained by Arnon’s procedure is briefly described below.
Effects of zinc application on the growth and photosynthetic characteristics of pecan at the seedling stage.
TLDR
It is shown that moderate soil Zn application promotes pecan growth and development by increasing photosynthesis, however excess Zn concentrations were not conducive to seedling growth.
Estimating fractional green vegetation cover of Mongolian grasslands using digital camera images and MODIS satellite vegetation indices
ABSTRACT Fractional green vegetation cover (FVC) is a useful indicator for monitoring grassland status. Satellite imagery with coarse spatial but high temporal resolutions has been preferred to
Modification of AlphaLISA Excitation Wavelength Leads to Improved Assay Sensitivity for Photosynthetic Tissue Samples
TLDR
A customized donor bead, modified for excitation outside the range of photosystem absorbance, was tested for its capacity to improve assay sensitivity with extracts containing photosynthetic pigments, potentially improving the overall utility of AlphaLISA technology.
Strongly enhanced luminescence of Sr4Al14O25:Mn4+ phosphor by co-doping B3+ and Na+ ions with red emission for plant growth LEDs
Development of a more cost-effective radiation source for use in plant-growing facilities would be of significant benefit for commercial crop production applications. A series of co-doped B3+ and Na+

Cloning and heterologous expression of chlorophyll a synthase in Rhodobacter sphaeroides
TLDR
The results demonstrated the feasibility of genetic engineering to combine chlorophyll and bacteriochlorophyll biosynthetic pathways which utilize common intermediates and improved absorption spectra and yield of photosynthesis and hydrogen gas production in bacteria.
Contribution made by the carotenoid cleavage dioxygenase 4 gene to yellow colour fade in azalea petals
TLDR
It is suggested that the high expression level of CCD4, which was inherited from ‘Miyamasatsuki’, was the main factor controlling the reduction in carotenoid content in the progeny.
EARLY INDUCTION OF SPROUTING ON SEED TUBERS OF YAM (Dioscorea spp.) SOON AFTER TUBER INITIATION IN A HYDROPONICS SYSTEM
TLDR
It is shown that the duration from vine emergence of the old tuber to sprouting of the new tuber can be reduced by more than half if young plants absorbed fluridone during early tuber development.
