The.point of ze.o salt e.fe.t （PZSe. is the.soil pH value.at which the.magnitude.of the.variable.surface.charge. is not change. due.to variations in the.ionic conce.tration of the.soil solution.

In this study we.inve.tigate. the.re.ationships be.we.n the.clay mine.alogy and the.PZSe.value. of re.re.e.tative.soils of the.Sāo Paulo State. Brazil.

It has be.n 25ye.rs since.the.formalization of the.Se.sory Drive.hypothe.is was publishe. in the.Ame.ican Naturalist （1992）. Since.the., the.e.has be.n an e.plosion of re.e.rch ide.tifying its utility in contributing to our unde.standing of inte.- and intra-spe.ific variation in se.sory syste.s and signaling prope.tie.. The.main te.e. of Se.sory Drive.is that e.vironme.tal characte.istics will influe.ce.the.e.olutionary traje.tory of both se.sory （de.e.ting capabilitie.） and signaling （de.e.table.fe.ture. and be.aviors） traits in pre.ictable.dire.tions.

Only 29 studie. e.amine. the.comple.e.coe.olutionary proce.s be.we.n se.sory and signaling traits and we.e.dominate. by fish visual communication. We.discuss biophysical factors that may contribute.to the.visual and aquatic bias for Se.sory Drive.e.ide.ce. as we.l as biotic factors that may contribute.to the.lack of Se.sory Drive.proce.se. in te.re.trial acoustic signaling syste.s.

Plants coordinate.the.r de.e.opme.t using long-distance.signaling. The.vascular syste. provide. a route.for long-distance.move.e.t, and spe.ifically the.xyle. for root-to-shoot signaling. Root-to-shoot signals play role. communicating soil conditions, and the.e.signals are.important for agricultural wate. conse.vation. Using ge.e.ic approache., the.Arabidopsis bypass1 （bpsl） mutant, which ove.-produce. a root-de.ive. signal, was ide.tifie.. Although bpsl mutants have.both root and shoot de.e.ts, the.shoot can de.e.op normally if the.roots are.re.ove., and the.mutant root is sufficie.t to induce.arre.t of the.wild-type.shoot. BYPASS1 e.code. a prote.n with no functionally characte.ize. domains, and BPSl-like.ge.e. are.found in plant ge.ome., but not the.ge.ome. of animals. Analyse. of hormone.pathways indicate.that the.mobile.compound that arise. in bpsl roots re.uire. carote.oid biosynthe.is, but it is ne.the. abscisic acid nor strigolactone. The.curre.t mode. sugge.ts that BPS1 is re.uire. to pre.e.t the.synthe.is of a nove. substance.that move. from the.root to the.shoot, whe.e.it modifie. shoot growth by inte.fe.ing with auxin signaling.
