Phytochemical Screening of 45‐Million‐Year‐Old Colored Angiosperm Leaves Reveals Distinctive Chlorophyll‐Derived and Polyphenolic Pigments

open access: yesGeobiology, Volume 24, Issue 1, January/February 2026.
ABSTRACT Present‐day angiosperm plants produce a plethora of metabolites including pigments that serve for important functions such as photosynthesis, protection against light, attraction of pollinators, and defense against microbes and herbivores. However, little is known about phytochemical constituents of ancient angiosperms, their distribution in ...

Cuticle Structure in Relation to Chemical Composition: Re-assessing the Prevailing Model [PDF]

open access: yes, 2015
The surface of most aerial plant organs is covered with a cuticle that provides protection against multiple stress factors including dehydration. Interest on the nature of this external layer dates back to the beginning of the 19th century and since then,

Memory in the wall: expanding our understanding of the roles of plant cell walls

open access: yesNew Phytologist, Volume 249, Issue 1, Page 56-72, January 2026.
Summary The plant cell wall, while providing mechanical support to cells, also dynamically adjusts its composition and structure in response to cellular and environmental cues. Recent findings indicate that plants exposed to cold stress alter the composition of cell wall polysaccharides and that this altered status primes the plants to overcome future,

Near infrared spectroscopy for predicting quality indices in the organic fertiliser industry [PDF]

open access: yes, 2007
The carbon to nitrogen (C/N) ratio can provide information on the capacity of an organic input to be transformed into humus [1 - 3], but it is not sufficient in some cases [4].
