Aluminium toxicity: oxidative stress during germination and early development in purple maize [PDF]
Revista Ciência Agronômica, 2022 Purple maize is a source of natural pigments that can be used for various industrial purposes; however, soil contamination from aluminium affects production. The aim of this study was to evaluate the effect of aluminium toxicity associated with different

Chlorophyll b to Chlorophyll a Conversion Precedes Chlorophyll Degradation in Hordeum vulgare L. [PDF]
Journal of Biological Chemistry, 1999 This study reveals by in vivo deuterium labeling that in higher plants chlorophyll (Chl) b is converted to Chl a before degradation. For this purpose, de-greening of excised green primary leaves of barley (Hordeum vulgare) was induced by permanent darkness in the presence of heavy water (80 atom % (2)H).

The derivation of the formyl-group oxygen of chlorophyll b in higher plants from molecular oxygen. [PDF]
, 1994 The mechanism of formation of the formyl group of chlorophyll b has long been obscure but, in this paper, the origin of the 7-formyl-group oxygen of chlorophyll b in higher plants was determined by greening etiolated maize leaves, excised from dark-grown

REACTIVITY OF CHLOROPHYLL a/b-PROTEINS AND MICELLAR TRITON X-100 COMPLEXES OF CHLOROPHYLLS a OR b WITH BOROHYDRIDE [PDF]
, 1989 The reaction of several plant chlorophyll-protein complexes with NaBH4 has been studied by absorption spectroscopy. In all the complexes studied, chlorophyll b is more reactive than Chi a, due to preferential reaction of its formyl substituent at C-7 ...

Mapping loci for chlorosis associated with chlorophyII b deficiency in potato [PDF]
, 2008 About 30% of the potato plants from a (Solanum tuberosum × S. berthaultii) × S. tuberosum backcross population had chlorotic, malformed leaves; but a gradation in symptom severity suggested regulation by more than one gene.

Spatial Variation of Leaf Chlorophyll in Northern Hemisphere Grasslands
Frontiers in Plant Science, 2020 Chlorophyll is the molecular basis for the function of photosystems and is also a promising tool for ecological prediction. However, the large-scale patterns of chlorophyll variation in grasslands remain poorly understood.
