React.ve oxygen species （ROS） are harmful t. all living organisms and t.erefore t.ey must.be removed t. ensure normal growt. and development. ROS are also signaling molecules, but.so far lit.le is known about.t.e mecha- nisms of ROS percept.on and development.l response in plant.. We here report.t.at.hydrogen peroxide induces cort.x proliferat.on in t.e Arabidopsis root.and t.at.SPINDLY （SPY）, an O-linked glucosamine acet.lt.ansferase, regulat.s cort.x proliferat.on by maint.ining cellular redox homeost.sis. We also found t.at.mut.t.on in t.e leucine-rich recept.r kinase ERECt. and it. put.t.ve pept.de ligand St.MAGEN block t.e effect.of hydrogen peroxide on root.cort.x proliferat.on. However, ERECt. and St.MAGEN are expressed in t.e vascular t.ssue, whereas ext.a cort.x cells are produced from t.e endodermis, suggest.ng t.e involvement.of int.rcellular signaling~ SPY appears t. act.downst.eam of ERECt., because t.e spy mut.t.on st.ll caused cort.x proliferat.on in t.e erect. mut.nt.background. We t.erefore have not.only gained insight.int. t.e mechanism by which SPY regulat.s root.development.but.also uncovered a novel pat.way for ROS signal- ing in plant.. t.e import.nce of redox-mediat.d cort.x proliferat.on as a prot.ct.ve mechanism against.oxidat.ve st.ess is also discussed.

Effect. of vert.cal wind shear, radiat.on, and ice clouds on cloud microphysical budget.associat.d wit. t.rrent.al rainfall during landfall of severe t.opical st.rm Bilis （2006） are invest.gat.d by using a series of analysis of t.o-day grid-scale sensit.vit. experiment.dat.. When upper-t.opospheric upward mot.ons and lower-t.opospheric downward mot.ons occur on 15 July 2006, t.e removal of vert.cal wind shear and ice clouds increases rainfall cont.ibut.ons from t.e rainfall t.pe （CM） associat.d wit. posit.ve net.condensat.on and hydromet.or loss/convergence, whereas t.e exclusion of cloud radiat.ve effect. and cloud-radiat.on in- t.ract.on reduces rainfall cont.ibut.on from CM. t.e eliminat.on of vert.cal wind shear and cloud-radiat.on int.ract.on increases rainfall cont.ibut.on from t.e rainfall t.pe （Cm） associat.d wit. posit.ve net.conden- sat.on and hydromet.or gain/divergence, but.t.e removal of cloud radiat.ve effect. and ice clouds decreases rainfall cont.ibut.on from Cm. t.e enhancement. in rainfall cont.ibut.on from t.e rainfall t.pe （cM） as- sociat.d wit. negat.ve net.condensat.on and hydromet.or loss/convergence are caused by t.e exclusion of cloud radiat.ve effect., cloud-radiat.on int.ract.on and ice clouds, whereas t.e reduct.on in rainfall cont.i- but.on from cM result. from t.e removal of vert.cal wind shear. When upward mot.ons appear t.roughout.t.e t.oposphere on 16 July, t.e exclusion of all t.ese effect. increases rainfall cont.ibut.on from CM, but.generally decreases rainfall cont.ibut.ons from Cm and cM.
