Natural variation in chalcone isomerase defines a major locus controlling radial stem growth variation among Populus nigra populations

Harold Duruflé, Annabelle Déjardin, Véronique Jorge, Marie Pégard et autres

Poplar is a promising resource for wood production and the development of lignocellulosic biomass, but currently available varieties have not been optimized for these purposes. Therefore, it is critical to investigate the genetic variability and mechanisms underlying traits that affect biomass yield. …

Cinnamyl alcohol dehydrogenase downregulation in poplar wood increases saccharification after dilute acid pretreatment: a key role for lignin revealed by a multimodal investigation

Julien du Pasquier, Aya Zoghlami, Youri Naudin, Annabelle Déjardin et autres

This study is the first to apply dilute acid pretreatment (DAP) under different severity conditions to poplar wood genetically modified for the cinnamyl alcohol dehydrogenase (CAD1) gene, which is involved in the lignin biosynthesis pathway. The carefully selected pretreatment conditions resulted in …

Immunolocalization of fasciclin-like arabinogalactan proteins in the G-layers of poplar tension wood fibers

Fernanda Trilstz Perassolo Guedes, Françoise Laurans, Nathalie Boizot, Annabelle Déjardin et autres

Abstract In hardwood trees, tension wood (TW) is an adaptive mechanism used by trees to orient their stems and branches, withstand their own weight, and improve wind resistance. In many species, such as poplar, TW fiber cell walls exhibit a supplemental layer, …

Can genome editing help transitioning to agroecology?

Fabien Nogué, Mathilde Causse, Philippe Debaeke, Annabelle Déjardin et autres

Meeting the challenges of agroecological transition in a context of climate change requires the use of various strategies such as biological regulations, adapted animal and plant genotypes, diversified production systems, and digital technologies. Seeds and plants, through plant breeding, play a crucial …

RNAseq based variant dataset in a black poplar association panel

Odile Rogier, Aurélien Chateigner, Marie-Claude Lesage-Descauses, Claire Mandin et autres

OBJECTIVE: Black poplar (Populus nigra L.) is a species native to Eurasia with a wide distribution area. It is an ecologically important species from riparian ecosystems, that is used as a parent of interspecific (P. deltoides x P. nigra) cultivated poplar hybrids. …

Field and saccharification performances of poplars severely downregulated in CAD1

Barbara De Meester, Rebecca Van Acker, Marlies Wouters, Silvia Traversari et autres

Lignin is one of the main factors causing lignocellulosic biomass recalcitrance to enzymatic hydrolysis. Glasshouse-grown poplars severely downregulated for CINNAMYL ALCOHOL DEHYDROGENASE 1 (CAD1), the enzyme catalysing the last step in the monolignol-specific branch of lignin biosynthesis, have increased saccharification yields and …

Duplication of NRAMP3 Gene in Poplars Generated Two Homologous Transporters with Distinct Functions

Mathieu Pottier, Van Anh Le Thi, Catherine Primard-Brisset, Jessica Marion et autres

Transition metals are essential for a wealth of metabolic reactions, but their concentrations need to be tightly controlled across cells and cell compartments, as metal excess or imbalance has deleterious effects. Metal homeostasis is achieved by a combination of metal transport across …
