Recognize BnSP specifically and get autophosphorylated, then phosphorylated SRK would phosphorylate ARC which could result in ubiquitination of its target proteins (e.g ExoA).An insertion of a DNA fragment using a length of bp in the promoter region of BnSP was responsible for the selfcompatibility (SC) of B.napus line “Westar” (Okamoto et al Tochigi et al).By complementing the function of BnSP in “Westar,” we obtained the transgenic line “W” which showed powerful SI (Gao et al).When pollen of “Westar” lands on its own stigma, compatible interaction occurs and standard pods are set; when pollen of “W” lands around the stigma of “Westar,” selfincompatible reaction happens and pods seldom set seeds.These are best components for us to shed further light around the complex responses of compatibleincompatible pollenstigma interactions using nextgeneration RNAseq coupled with a comprehensive timecourse experiment.Supplies AND Approaches Plant Material and Growth ConditionsThe wild type selfcompatible B.napus line “Westar” and transgenic selfincompatible line “W” (Gao et al) were grown within the greenhouse with h daynight photoperiod and temperatures of C.Floral buds of wild kind selfcompatible B.napus line “Westar” have been emasculated day before anthesis to prevent pollen contamination.The subsequent day, stigma samples were collected by cutting the pistil just below the base of the stigma and quickly frozen in liquid nitrogen.By this system, stigma samples of “Westar” with no pollen pollinated (UP) and pollinated stigmas (Coenzyme A medchemexpress Computer, Computer, Computer, Computer, Pc selfpollinated stigmas of “Westar” at , , , , and min; PI, PI, PI, PI, PI stigmas of “Westar” pollinated with all the incompatible pollen of “W” at , , , , and min) were collected.Transmission Electron MicroscopyThe pollinated stigmas (PI and Pc) had been vacuuminfiltrated and prefixed within a resolution of .glutaraldehyde adjusted to pH .with .M phosphate buffer, fixed in OsO inside the very same buffer, and then dehydrated and embedded in epoxyFrontiers in Plant Science www.frontiersin.orgMay Volume ArticleZhang et al.PollenStigma Interactions in Brassica napus L.resin and SPI (Structure Probe, Inc www.spi.com), respectively.Ultrathin sections had been obtained utilizing a Leica UC ultramicrotome (www.leica.com) and have been stained with uranyl acetate and subsequently with lead citrate.The observations and recording of pictures have been performed using a Hitachi H transmission electron microscope (www.hitachihitec.com) at kV plus a Gatan CCD camera (www.gatan.com).cDNA synthesis was performed working with a SuperScript kit (Gibco BRL, www.invitrogen.com).Realtime RTPCR was also performed applying a BioRad IQ with SYBR Green detection (www.biorad.com).Actin (GeneBank accession no.
