p-Coumaroylation of lignin occurs outside of commelinid monocots in the eudicot genusMorus(mulberry) [PDF]
Plant Physiology, 2023 AbstractThe presence of p-coumarate (pCA) in plant cell walls is generally considered to be a trait present only in commelinid monocots. Here, we show that this long-held overgeneralizing assumption is incorrect and that mulberry trees (Morus) are eudicot plants that have lignins derived in part from monolignol pCA esters.

Modification of plant cell walls with hydroxycinnamic acids by BAHD acyltransferases [PDF]
Frontiers in Plant Science, 2023 In the last decade it has become clear that enzymes in the “BAHD” family of acyl-CoA transferases play important roles in the addition of phenolic acids to form ester-linked moieties on cell wall polymers.

RNA editing in the chloroplast of Asian Palmyra palm (Borassus flabellifer) [PDF]
Genetics and Molecular Biology, 2020 We have identified 46 RNA editing sites located in 20 chloroplast (cp) genes of Borassus flabellifer (Asian Palmyra palm), family Arecaceae, and tested these genes for supporting phylogenetic study among the commelinids. Among the 46 sites, 43 sites were

Identification of universal grass genes and estimates of their monocot-/commelinid-/grass-specificity. [PDF]
Bioinform AdvAbstract Motivation Where experiments identify sets of grass genes of unknown function, e.g. underlying a QTL or co-expressed in a transcriptome, it is useful to know which of these genes are common to all grasses (universal) and whether they likely have monocot-/commelinid-/grass-specific function.

2D-HSQC-NMR-Based Screening of Feruloylated Side-Chains of Cereal Grain Arabinoxylans [PDF]
Frontiers in Plant Science, 2022 Arabinoxylans of commelinid monocots are characterized by high contents of ferulic acid that is incorporated into arabinose-bearing side-chains of varying complexity.

Biosilicification in monocots: Comparative analysis highlights contrasting patterns of deposition. [PDF]
Am J BotAbstract Premise New insights into biomineral uptake and sequestration are important for understanding how plants grow. Some plants accumulate silica accretions in precise locations in particular cells. Among monocots, controlled biosilicification occurs in several different forms and is restricted to commelinids and orchids. Methods We utilized energy‐

Evolution, Systematics and Classification of Commelinales (Commelinids, Monocots) Based on a Giant Morphological Taxon-Character Matrix. [PDF]
Plants (Basel)Despite being strongly recovered as monophyletic by molecular studies, Commelinales completely lacks any morphological support or circumscription. It is also the Monocot order that suffered the most striking changes across different classification systems, with its type family, Commelinaceae, being the only consistent member since its proposition.

Physiological roles of lignins - tuning cell wall hygroscopy and biomechanics. [PDF]
New PhytolSummary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their

Historical biogeography and plastome evolution of Commelinaceae Mirb. (Commelinales) corroborate the East Gondwanan origins [PDF]
BMC Plant BiologyBackground Commelinaceae are a Pantropical monocot family comprising ca. 36 genera and 810 species. Due to the high morphological variation and limited sampling, the relationships within the family remain unclear.
