Ecosphere, 2019 AbstractWeedy rice (Oryza sativa f. spontanea) is a conspecific weedy relative of cultivated Asian rice (O. sativa L.) that occurs in paddy fields worldwide. The mechanism underlying the persistence of weedy rice in rice fields remains unclear. We tested for evidence that southern Chinese weedy rice has originated through pollen flow from weedy rice ...
