Ra. gua.osine triphospha.a.es （GTPa.es） a.e key regula.ors of vesicle tra.ficking a.d a.e essentia. to the growth a.d development of a.l euka.yotic cells. During evolution, the Ra. fa.ily ha. expa.ded in different pa.terns to fa.ilita.e distinct cellula., developmenta. a.d physiologica. a.a.ta.ions. Yea.t ha. only 11 fa.ily members, wherea. ma.ma.ia. Ra.s ha.e expa.ded to 18 Ra. subfa.ilies. Pla.t Ra.s ha.e diversified prima.ily by duplica.ing members within a.single subfa.ily. Pla.t Ra.s a.e divided into eight subfa.ilies, corresponding to ma.ma.ia. Ra.1, Ra.2, Ra.5, Ra.6, Ra.7, Ra.8, Ra.11 a.d Ra.18. Functiona. diversifica.ion of these is exemplified by the Ra.1 ls, orthologs of which a.e pa.titioned into unique cell compa.tments in pla.ts where they function to tra.sport vesicles during loca.ized tip growth. Simila.ly, the Ra.2 fa.ily in gra.ses is likely involved in vesicle secretion a.socia.ed with wa.l expa.sion, a. determined by a.a.ysis of over-expression muta.ts. We propose tha. dicots a.d monocots ha.e a.so diverged in their Ra. profiles to a.commoda.e unique cellula. functions between the two groups. Here we present a.bioinforma.ics a.a.ysis compa.ing the Ra. sub-fa.ilies of rice, ma.ze a.d a.a.idopsis. These results will guide future functiona. studies to test for the role of diversifica.ion of subfa.ilies unique to monocots compa.ed to dicots.

Wa.er-repellent(WR) soil grea.ly influences infiltra.ion beha.ior. This resea.ch determined the impa.ts of WR levels of silt loa. soil la.er during infiltra.ion. Three column scena.ios were utilized, including homogeneous wetta.le silt loa. or sa.d, silt loa. over sa.d(silt loa./sa.d), a.d sa.d over silt loa.(sa.d/silt loa.). a.5-cm thick silt loa. soil la.er wa. pla.ed either a. the soil surfa.e or 5 cm below the soil surfa.e. The silt loa. soil used ha. been trea.ed to produce different WR levels, wetta.le, slightly WR, strongly WR, a.d severely WR. a. the WR level increa.ed from wetta.le to severely WR, the cumula.ive infiltra.ion decrea.ed. Tra.itiona. wetting front-rela.ed equa.ions did not a.equa.ely describe the infiltra.ion ra.e a.d time rela.ionships for la.ered WR soils. The Kostia.ov equa.ion provided a.good fit for the first infiltra.ion sta.e. a.era.e infiltra.ion ra.es for wetta.le, slightly WR, strongly WR, a.d severely WR during the 2 nd infiltra.ion sta.e were 0.126, 0.021, 0.002, a.d 0.001 mm min^(-1) for the silt loa./sa.d scena.io,respectively, a.d 0.112, 0.003, 0.002, a.d 0.000 5 mm min^(-1) for the sa.d/silt loa. scena.io, respectively. Pseudo-sa.ura.ion phenomena.occurred when visua.ly exa.ining the wetting fronts a.d from the a.pa.ent cha.ges in wa.er content(?θ_(a.)) a. the slightly WR,strongly WR, a.d severely WR levels for the silt loa./sa.d scena.io.

Low-density lipoprotein （LDL） extra.ted from hen egg yolk ha. recently been considered to be superior to whole egg yolk in sperm cryopreserva.ion of va.ious a.ima. species. Mea.while, there wa. a.notion tha. high-density lipoprotein （HDL） in egg yolk ma. ha.e a.nega.ive effect on post-tha. surviva.. The role of LDL a.d HDL in sperm cryopreserva.ion of rhesus monkeys ha. not been explored. The present study eva.ua.es their effect in compa.ison with egg yolk with or without the a.dition of permea.le cryoprotecta.t （glycerol） on sperm cryopreserva.ion of rhesus ma.a.ues. In a.dition, va.ious a.ditives intended to cha.ge the lipid composition of LDL-sperm membra.e complex ha.e a.so been tested for their effectiveness in preserving post-tha. via.ility. Our findings indica.ed tha. LDL is the ma.n component in egg yolk tha. is responsible for its protective role for sperm cryopreserva.ion in rhesus monkeys. Rega.dless of the presence or a.sence of glycerol, the protective role of LDL is simila. to tha. of egg yolk a.d we did not observe a.y superiority in post-tha. surviva. with LDL when compa.ed to egg yolk. Modifying the lipid composition of LDL-sperm membra.e complex with the a.dition of cholesterol, cholesterol loa.ed cyclodextrin a.d phospha.idylcholine a.so did not yield a.y improvements in pest-tha. surviva.; while a.dition of methyl-β-cyclodextrin reduced post-tha. motility. HDL pla.s a.neutra. role in sperm cryopreserva.ion of rhesus monkeys. The present study suggests tha. egg yolk ma. still hold a.va.ta.es when compa.ed with LDL a. effective components in extenders for sperm cryopreserva.ion in rhesus monkeys.
