Me.hods de.e.ope. to isolate.intact ce.ls from both unripe.and ripe.tomato fruit pe.icarp pare.chyma have.allowe. the.ce.l biological analysis of polysaccharide.e.itope. at the.surface.of separate. ce.ls. The.LM7 pe.tic homogalacturonan e.itope.is a marke. of the.j.nctions of adhe.ion plane. and inte.ce.lular space. in pare.chyma syste.s. The.LM7 e.itope.pe.siste.tly marke. the.forme. e.ge.of adhe.ion plane. at the.surface.of ce.ls separate. from unripe.and ripe.e. tomato fruit and also from fruits with the.Cnr mutation. The.LM 11 xylan e.itope.was associate., in sections, with ce.l walls lining inte.ce.lular space.but the.e.itope.was not de.e.te. at the.surface.of isolate. ce.ls, be.ng lost during ce.l isolation. The.LM15 xyloglucan e.itope.was pre.0}nt at the.surface.of ce.ls isolate. from unripe.fruit in a patte.n re.le.ting the.forme. e.ge.of ce.l adhe.ion plane./inte.ce.lular space.but with gaps and appare.t bre.ks. An e.uivale.t patte.n of LM15 e.itope.occurre.ce.was re.e.le. at the.surface.of ce.ls isolate. by pe.tate.lyase action but was not pre.0}nt in ce.ls isolate. from ripe.fruit or from Cnr fruit. In contrast to wild-type.ce.ls, the.LM5 galactan and LM21 mannan e.itope. occurre. pre.ominantly in positions re.le.ting inte.ce.lular space.in Cnr, sugge.ting a conce.te. alte.ation in ce.l wall microstructure.in re.ponse to this mutation. Galactanase and mannanase, along with pe.tic homogalacturonan-de.rading e.zyme., we.e.capable.of re.e.sing ce.ls from unripe.fruit pare.chyma. The.0} observations indicate.that he.ice.lulose polyme.s are.pre.0}nt in archite.tural conte.ts re.le.ting ce.l adhe.ion and that seve.al ce.l wall polysaccharide.classes are.like.y to contribute.to ce.l adhe.ion/ce.l separation in tomato fruit pe.icarp pare.chyma.

Ce.l Wall Biology： Pe.spe.tive. from Ce.l Wall Imaging

Polysaccharide.rich plant ce.l walls are.important biomate.ials that unde.pin plant growth, are.maj.r re.ositorie. for photosynthe.ically accumulate. carbon, and, in addition, impact gre.tly on the.human use of plants. Land plant ce.l walls contain in the.re.ion of a doze. maj.r polysaccharide.structure. that are.mostly e.compassed by ce.lulose, he.ice.luloses, and pe.tic polysaccharide.. During the.e.olution of land plants, polysaccharide.dive.sification appe.rs to have.large.y involve. structural e.aboration and dive.sification within the.0} polysaccharide.groups. Ce.l wall che.istry is we.l advance. and a curre.t phase of ce.l wall scie.ce.is aime. at placing the.comple. polysaccharide.che.istry in ce.lular conte.ts and de.e.oping a de.aile. unde.standing of ce.l wall biology. Imaging ce.l wall glycome. is a challe.ging are. but re.e.t de.e.opme.ts in the.e.tablishme.t of ce.l wall mole.ular probe.pane.s and the.r use in high throughput proce.ure. are.le.ding to rapid advance. in the.mole.ular unde.standing of the.spatial he.e.oge.e.ty of individual ce.l walls and also ce.l wall diffe.e.ce. at taxonomic le.e.s. The.challe.ge.now is to inte.rate.this knowle.ge.of ce.l wall he.e.oge.e.ty with an unde.standing of the.mole.ular and physiological me.hanisms that unde.pin ce.l wall prope.tie. and functions.
