What's the difference between lignification and signification?
Lignification
Definition:
(n.) A change in the character of a cell wall, by which it becomes harder. It is supposed to be due to an incrustation of lignin.
Example Sentences:
(1) An Italian "Dalita" ryegrass (Lolium italicum) and a European lucerne (Medicago sativa) were harvested at 5 different growth stages to determine the anatomical factors limiting their digestibility and in particular the effects of lignification of the tissues.
(2) The possible relationship between pectic polysaccharide-xylan-phenolic complexes and the onset of lignification in maturing tissues is discussed.
(3) The observation that the oxidation of CA by cell wall peroxidase at the expense of IAA and O2 is inhibited by genistein, a putative endogenous inhibitor of lignification in lupin hypocotyls, supports the view that the H2O2-generating system coexists with cell wall peroxidase activities involved in lignification, and that it takes place at the expense of IAA and O2.
(4) Surface area equations based on lignification of NDF accurately estimated fiber digestion and suggested that lignification was the primary reason DM and NDF digestibilities decreased with advanced maturity.
(5) It is also found that the degree of lignification of fibres and medullary cells of the herbaceous stems is related to the positions and diameters of the stems.
(6) The data suggest that beta-glucosidase-catalyzed reaction might be involved in lignification of these plant cell cultures.
(7) The regulatory significance of the rapid activation of this CAD gene and the possible existence of a second, divergent CAD gene involved in lignification during xylogenesis are discussed.
(8) We have isolated a full-length cDNA clone encoding CAD, as a molecular marker specific for lignification, by immunoscreening a lambda gt11 library containing cDNAs complementary to mRNA from elicitor-treated cell cultures of bean (Phaseolus vulgaris L.).
(9) This peroxidase-catalyzed reaction has been proposed for the plant peroxidases involved in lignification.
Signification
Definition:
(n.) The act of signifying; a making known by signs or other means.
(n.) That which is signified or made known; that meaning which a sign, character, or token is intended to convey; as, the signification of words.
Example Sentences:
(1) Insulin requirement in the treated groups was significantly lower than in control group at 6 months, this difference was no longer significative at 12 months.
(2) The intrinsic viscosity of hyaluronic acid in synovial fluid decreases significatively in mild and severe arthritis (24% and 37% respectively).
(3) Statistical analysis of regression lines obtained in both groups of patients showed significative differences between slopes and elevations.
(4) It was found that the nurses' knowledge of AIDS was limited: they do not understand the signification of seropositivity and they had little knowledge of the epidemiological dimensions of the illness.
(5) Fractional excretion of potassium did not change in the control group after nephrectomy while the ethanol-fed group displayed a significative decrease at days 7 and 14.
(6) At the end of the tests the development of the most significative symptomatologic parameters has been analysed according to the Wilcoxon test: quantity, kind and characteristics of nasal secretions, nasal obstruction, phlogosis of the nasal and pharyngeal mucosa, hoarseness, difficulty in catarrhal expectoration, hypoacusia, retraction of the tympanic membrane.
(7) In spite of a significative descent of arterial pressure, we did not find any significative change in the fetal heart rate, accelerations, variability, or in the fetal motility.
(8) The bentazepam treatment cut down significatively the score mean in Hamilton scale for the anxiety after 10-15 days of treatment.
(9) The percentage of reactors increased from 30% among healthy subjects to 45,9% among the those attending the day hospital and to 60% among those admitted to wards; this is statistically significative.

(11) not any other parameter had significative relation with the neurotransmitters variations.
(12) On 122 validated cases out of 188 analyzed patients, the study demonstrates a significative effect on the mortality and severe morbidity related to vasospasm: the reduction of the risk is appreciated to 72%.
(13) The author points out the transport proteins whose biological roles are not completely known and ascertains that the free hormone concept has not at the present time a biological signification well defined.
