“…Most diploids in the genus, including S. noctiflora , have a chromosome number of 2 n = 24, which is likely the ancestral number ( Bari 1973 ; McNeill 1980 ; Yildiz et al 2008 ; Kemal et al 2009 ; Gholipour and Sheidai 2010 ; Ghasemi et al 2015 ; Mirzadeh Vaghefi and Jalili 2019 ). There are also numerous polyploid Silene species, including tetraploid, hexaploid, and octaploid forms ( Kruckeberg 1960 ; Popp and Oxelman 2001 , 2007 ; Popp et al 2005 ; Bai et al 2012 ).…”

“…Silene noctiflora ( Figure 1 ) is largely hermaphroditic but can produce a mixture of hermaphroditic and male-sterile flowers on the same plant (gynomonoecy) ( Davis and Delph 2005 ). Also known as the night-flowering catchfly, this annual species is native to Eurasia and introduced throughout much of the world ( McNeill 1980 ; Davis and Delph 2005 ).…”

The angiosperm genus Silene is a model system for several traits of ecological and evolutionary significance in plants, including breeding system and sex chromosome evolution, host-pathogen interactions, invasive species biology, heavy metal tolerance, and cytonuclear interactions. Despite its importance, genomic resources for this large genus of approximately 850 species are scarce, with only one published whole-genome sequence (from the dioecious species S. latifolia). Here, we provide genomic and transcriptomic resources for a hermaphroditic representative of this genus (S. noctiflora), including a PacBio Iso-Seq transcriptome, which uses long-read, single-molecule sequencing technology to analyze full-length mRNA transcripts. Using these data, we have assembled and annotated high-quality full-length cDNA sequences for approximately 14,126 S. noctiflora genes and 25,317 isoforms. We demonstrated the utility of these data to distinguish between recent and highly similar gene duplicates by identifying novel paralogous genes in an essential protease complex. Further, we provide a draft assembly for the approximately 2.7-Gb genome of this species, which is near the upper range of genome-size values reported for diploids in this genus and three-fold larger than the 0.9-Gb genome of S. conica, another species in the same subgenus. Karyotyping confirmed that S. noctiflora is a diploid, indicating that its large genome size is not due to polyploidization. These resources should facilitate further study and development of this genus as a model in plant ecology and evolution.

“…S. noctiflora has been previously reported as a diploid (2n=24) (McNeill 1980;Yildiz et al 2008;Ghasemi et al 2015). Given its relatively large genome size, we sought to confirm this result in our sampled population with a karyotype analysis (Figure 4), which indeed supported the conclusion that that S. noctiflora OPL is diploid.…”

The angiosperm genus Silene is a model system for several traits of ecological and evolutionary significance in plants, including breeding system and sex chromosome evolution, host-pathogen interactions, invasive species biology, heavy metal tolerance, and cytonuclear interactions. Despite its importance, genomic resources for this large genus of approximately 850 species are scarce, with only one published whole-genome sequence (from the dioecious species S. latifolia). Here, we provide genomic and transcriptomic resources for a hermaphroditic representative of this genus (S. noctiflora), including a PacBio Iso-Seq transcriptome, which uses long-read, single-molecule sequencing technology to analyze full-length mRNA transcripts and identify paralogous genes and alternatively spliced genes. Using these data, we have assembled and annotated high-quality full-length cDNA sequences for approximately 17,000 S. noctiflora genes and 27,000 isoforms. We demonstrated the utility of these data to distinguish between recent and highly similar gene duplicates by identifying novel paralogous genes in an essential protease complex. Further, we provide a draft assembly for the approximately 2.7-Gb genome of this species, which is near the upper range of genome-size values reported for diploids in this genus and three-fold larger than the 0.9-Gb genome of S. conica, another species in the same subgenus.

“…The white flowers of S. noctiflora develop between June and September and are nocturnal, opening at night to release a fragrance that attracts nocturnal moths. However, the species is also self‐compatible (McNeill ). Both are considered weed species in agricultural areas, and are in decline in their native habitats (Sutcliffe and Kay ).…”

Plant competitive interactions influence the effect of herbicides, and the effect of competitive interactions on plant responses may be important to include in the ecological risk assessment of herbicides. In the present study the effect of competitive interactions and sublethal doses of 2 herbicides on plant species was investigated in competition experiments and fitted to empirical competition models. Two nontarget species commonly found in agroecosystems (Centaurea cyanus L. and Silene noctiflora L.) and 2 herbicides (glyphosate and metsulfuron methyl) were used in separate experiments. Plants were sprayed at the 6‐ to 8‐leaf stage. Effects of herbicide treatments and plant density were modeled by generalization of a discrete hyperbolic competition model. The 10% effective dose (ED10) was calculated for C. cyanus. All experiments showed that as density increased, plants were negatively affected. Furthermore, in all cases, C. cyanus remained a better competitor than S. noctiflora. Nevertheless, the density of S. noctiflora (competitor) was an influential element in determining the ED10 of C. cyanus measured at the mature stage. With herbicide exposure, the competitive interactions were further altered; C. cyanus was less affected by glyphosate when S. noctiflora increased to high density. In contrast, at the young stage, conspecific density was important in determining the sensitivity of C. cyanus to metsulfuron methyl, whereas the density of the competitor S. noctiflora had a limited influence. Overall, the results demonstrate the importance of integrating the effect of herbicide and species interactions measured at the reproductive stage into the ecological risk assessments of pesticides.
