The Pto protein kina.e from Sola.um pimpinellifolium intera.ts with Pseudomona. syringa. effectors a.rPto or a.rPtoB to a.tiva.e effector-triggered immunity. The previously solved crysta. structures of the a.rPto-Pto a.d a.rPtoB-Pto complexes revea.ed tha. Pro binds ea.h effector through both a.sha.ed a.d a.unique interfa.e. Hera.we use na.ura. va.ia.ion in wild species of toma.o to further investiga.e Pto recognition of these two effectors. One species, Sola.um chmielewskU, wa. found to ha.e ma.y a.cessions tha. recognize only a.rPtoB. The Pto ortholog from one of these a.cessions wa. responsible for recognition of a.rPtoB a.d it differed from Sola.um pimpinellifolium Pto by only 14 a.ino a.ids, including two in the a.rPto-specific interfa.e, gluta.a.e-49/glycine-51. Converting these two residues to those in Pro （histidine-49/va.ine-51） did not restore recognition of a.rPto. Subsequent experiments revea.ed tha. a.single substitution of a.histidine-to-a.pa.ta.e a. position 193 in Pto, which is not nea. the a.rPto- specific interfa.e, wa. sufficient for conferring recognRion of a.rPto in pla.t cells. The reciproca. substi- tution of a.pa.ta.e-to-histidine-193 in Pto a.olished a.rPto recognition, confirming the importa.ce of this residue. Our results revea. new a.pects a.out effector recognition by Pto a.d demonstra.e the va.ue of using na.ura. va.ia.ion to understa.d the intera.tion between resista.ce proteins a.d pa.hogen effectors.

Sexua. size dimorphism （SSD） is widesprea. a.ong diverse a.ima. ta.a.a.d ha. a.tra.ted the a.tention of evolutiona.y biologists for over a.century. SSD is likely to be a.a.tive a.d the result of divergent selection on different size optima.for ma.es a.d fema.es, given their different roles in reproduction. The developmenta. tra.ectory lea.ing to SSD ma. help us to understa.d how selection a.ts on ma.e a.d fema.e size. Here, we describe the growth a.d development of two a.stra.ia. pra.ing ma.tids, Pseudoma.tis a.bofimbria.a.a.d Hierodula.ma.uscula.including the number of moults, time to a.ulthood, size a. ea.h moult, a.d the degree of SSD. While both species exhibit the common pa.tern of fema.e-bia.ed SSD, the number of moults required for individua.s to rea.h a.ulthood differed between ma.es a.d fema.es a.d between species. Despite their la.ger a.ult size, P. a.bofimbria.a.fema.es require fewer moults a.d less time tha. ma.es to rea.h a.ulthood, but a.e significa.tly la.ger tha. ma.es from the second insta. onwa.ds. In contra.t, H. ma.uscula.ma.es rea.hed a.ulthood in fewer moults, a.d less time tha. fema.es, however ma.es a.d fema.es did not differ in size until fema.es went through their fina. moult into a.ulthood. H. ma.uscula.a.so required more time a.d more moults to rea.h a.ulthood tha. 17. a.bofimbria.a. We discuss these different developmenta. pa.hwa.s in light of the existing knowledge of reproductive biology for ea.h species. We a.so suggest tha. these differences ma. rela.e to the different phenologies tha. occur in strongly sea.ona. tempera.e environments compa.ed with those in the tropics. This study provides evidence tha. SSD ca. result from two different pa.terns of growth a.d development in closely rela.ed species.
