DNA transposon activity is associated with increased mutation rates in genes of rice and other grasses by Wicker, Thomas, Yu, Yeisoo, Haberer, Georg, Mayer, Klaus F. X., Marri, Pradeep Reddy, Rounsley, Steve, Chen, Mingsheng, Zuccolo, Andrea, Panaud, Olivier, Wing, Rod A., Roffler, Stefan

“…Analysing over 650 transposon polymorphisms in the rice species Oryza sativa and Oryza glaberrima, we find that DNA repair following transposon excisions is associated with an increased number of mutations in the sequences neighbouring the transposon. …”

Genetic control of seed shattering during African rice domestication by Lv, S., Wu, W., Wang, M., Meyer, R.S., Ndjiondjop, M.N., Tan, L., Zhou, H., Zhang, J., Fu, Y., Cai, H., Sun, C., Wing, Rod A., Zhu, Z.

“…Moreover, selecting a genomic segment deletion containing SH3 resulted in the loss of seed dispersal in populations of African cultivated rice (Oryza glaberrima Steud.). Functional characterization of SH3 and SH4 (another gene controlling seed shattering on chromosome 4) revealed that multiple genes can lead to a spectrum of non-shattering phenotypes, affecting other traits such as ease of threshing that may be important to tune across different agroecologies and postharvest practices. …”
