“…For example, Zhang et al reported that 32 crabgrass populations collected from the north and northeast of China have evolved resistance to nicosulfuron. Mei et al mentioned that NTSR mechanisms are the main reason for high crabgrass resistance to nicosulfuron in China. Previous studies have shown that many weed species can exhibit from one to several coexisting resistance mechanisms, both non‐target‐site and target‐site based .…”

“…ALS inhibitors, which exhibit excellent efficacy to control broadleaf weeds and sedges in paddy fields, are widely and continuously used; however, more and more weeds are becoming resistant to these herbicides. Some prominent examples are Amaranthus retroflexus L. (redroot amaranth), Descu- tions [25][26][27][28]. In the rice paddy fields, S. trifolia has become the dominant weed species in the northeast of China since 2010, and it has developed resistance to SU herbicides [2].…”

Herbicide resistance to sulfonylureas in Sagittaria trifolia L. is a common problem in northern China. In our study, we used whole-plant dose-response, acetolactate synthase (ALS) sequencing, and ALS enzyme activity methods to assess 3 putative resistant (LN-1, LN-2, and LN-3) and one susceptible (S) S. trifolia populations for crossresistance to ALS inhibitors (bensulfuron-methyl, ethoxysulfuron, pyrazosulfuron-ethyl, penoxsulam, pyribenzoxim, and bispyribac-sodium). Regarding the whole-plant dose-response and the in vitro ALS assays, the results showed that the LN-2 population evolved cross-resistance to all herbicides tested whereas the other two populations showed crossresistance only to bensulfuron-methyl, ethoxysulfuron, pyrazosulfuron-ethyl, and penoxsulam. Results of the in vitro ALS assays were consistent with whole-plant dose-response data. The DNA sequencing of the ALS gene showed that LN-1 and LN-3 populations had a single nucleotide polymorphism in the Pro 197 codon, resulting in the substitution of proline (Pro) by serine (Ser) and leucine (Leu), respectively. However, the LN-2 population showed single nucleotide polymorphism in the second position of the Asp 376 codon, causing substitution of aspartic acid (Asp) by glutamic acid (Glu). The cross-resistance of the S. trifolia population to all ALS inhibitors due to Asp 376 mutation in the ALS gene of this species is reported for the first time.

“…52 In addition, Mei et al 53 found that one or more P450s may be involved in large crabgrass (Digitaria sanguinalis L.) resistance to nicosulfuron and non-target site resistance mechanisms may responsible for the resistance. 53 Zhao et al 54 demonstrated that the BC1 population of threeleaf arrowhead (Sagittaria trifolia L.) has evolved a non-target site resistance mechanism to ALS-inhibiting herbicides. 54 All of these papers present a phenomenon that the resistance was related with non-target site resistance mechanisms but they did not provide a specific change in coding or non-coding regions that fully explain how and why such changes occurred.…”

BACKGROUND Genomes are vital to the study of genomics, population genetics, and evolution of species. To date, only one genome (Echinochloa crus‐galli) for C4 annual weedy grass species has been sequenced. Research was conducted to develop a draft genome of goosegrass (Eleusine indica; 2n = 2x = 18), one of the most common and troublesome weeds in the world. RESULTS A draft assembly of an approximately 492 Mb whole‐genome sequence of goosegrass was obtained by de novo assembly of paired‐end and mate‐paired reads generated by Illumina sequencing of total genomic DNA. The genome was assembled into 24,072 scaffolds with N50 = 233,459 bp. More than 99% of transcriptome sequences were mapped to the goosegrass draft genome, and 95% of the commonly conserved plant genes were present. The assembled genome contains 25,467 unique protein‐coding genes. Genes associated with herbicide resistance were obtained and variant calling allowed the detection of 754,409 single nucleotide polymorphisms. In addition, we also report 115,417 simple sequence repeats which can be deployed in population genetics and phylogenetic analysis. CONCLUSION This is the first report of genome sequence of goosegrass. Our assembly was able to identify all major herbicide‐resistance related genes and develop a useful tool for other genomic and evolutionary analysis. © 2019 Society of Chemical Industry
