Record 1 2002-03-21

English

Subject field(s)
  • Xylology (The Study of Wood)
  • Plant Biology
  • Genetics
  • Biochemistry
DEF

A threadlike component of cell walls, visible under an optical microscope.

OBS

This term, used without qualification,=macrofibril, in contrast to the ultrastructural microfibril.

OBS

this groove ... deepens, cuts through the spindle fibrils, and ... constricts the cell into two daughter cells.

French

Domaine(s)

DEF

Élément structural filiforme des parois cellulaires, visible au microscope optique ou photonique.

OBS

Ce terme employé sans spécification est équivalent à : macro-fibrille et il s'oppose à micro-fibrille visible au microscope électronique.

OBS

[...] entre deux divisions cellulaires, [la chromatine] se présente sous forme de fibrilles constituées d'ADN.

Record 3 1997-03-20

English

Subject field(s)
  • Genetics
CONT

Cellulose is one of the most important primary plant products, yet its biosynthetic pathway remains obscure. Freeze fracture studies have revealed that organized macromolecular structures ’terminal complexes’ are present on the plasma membrane, and are associated with cellulose microfibril assembly. A variety of techniques have been developed to isolate and characterize components of this cellulose synthesis complex, and to reconstitute the biosynthetic apparatus in vitro.

French

Domaine(s)
  • Génétique
CONT

L'impossibilité de transduire des cellules musculaires in vivo a récemment été rapportée, les particules étant incapables de franchir la membrane basale. Parallèlement, les méthodes non virales, en particulier les complexes de synthèse comportant des ligands spécifiques pour une cible cellulaire d'intérêt, soulèvent un intérêt considérable.
