TEMPO-oxidized cellulose nanofibers.
The new cellulose-based nanofibers formed by size reduction process of native cellulose fibers by TEMPO-mediated oxidation have potential application as environmentally friendly and new bio- based nanomaterials in high-tech fields.
Cellulose nanofibers prepared by TEMPO-mediated oxidation of native cellulose.
Never-dried and once-dried hardwood celluloses were oxidized by a 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-mediated system, and highly crystalline and individualized cellulose nanofibers,
Comparative analysis of the self‐incompatibility (S‐) locus region of Prunus mume: identification of a pollen‐expressed F‐box gene with allelic diversity
Understanding how S‐RNase causes S‐haplotype specific inhibition of pollen tubes has been hampered by the lack of a cloned pollen S‐determinant gene.
Homogeneous suspensions of individualized microfibrils from TEMPO-catalyzed oxidation of native cellulose.
Never-dried native celluloses (bleached sulfite wood pulp, cotton, tunicin, and bacterial cellulose) were disintegrated into individual microfibrils after oxidation mediated by the
TEMPO-mediated oxidation of native cellulose. The effect of oxidation conditions on chemical and crystal structures of the water-insoluble fractions.
Water retention values of cotton linter can be increased from 60% to about 280% through the introduction of hydrophilic carboxylate groups and morphological changes from fibrous forms to short fragments by the TEMPO-mediated oxidation.
Self-incompatibility in plants.
Recent advances in the understanding of three distinct SI mechanisms, each controlled by two separate determinant genes at the S-locus are discussed.
Collaborative Non-Self Recognition System in S-RNase–Based Self-Incompatibility
The findings reveal a collaborative non-self recognition system in plants and show that in Petunia, at least three types of divergent SLF proteins function as the pollen determinant, each recognizing a subset of non- self S-RNases.
Transparent and high gas barrier films of cellulose nanofibers prepared by TEMPO-mediated oxidation.
The T OCN films prepared from softwood cellulose were transparent and flexible and had extremely low coefficients of thermal expansion caused by high crystallinity of TOCN, which is promising for potential applications in some high-tech materials.
Direct ligand–receptor complex interaction controls Brassica self-incompatibility
It is shown that a single form of SP11 of the S8 haplotype (S8-SP11) stabilized with four intramolecular disulphide bonds specifically binds the stigma membrane of theS8 haplotypes to induce autophosphorylation of SRK8, and thatSRK8 and SLG8 together form a high-affinity receptor complex for S8- SP11 on the stigma membranes.
Elastic modulus of single cellulose microfibrils from tunicate measured by atomic force microscopy.
The result showed that the experimentally determined modulus of the highly crystalline tunicate microfibrils was in agreement with the elasticModulus of native cellulose crystals.
