Silene latifolia and its pollinator, the noctuid moth hadena bicruris, represent an open nursery pollination system wherein floral volatiles, especially veratrole (1, 2-dimethoxybenzene), lilac aldehydes, and phenylacetaldehyde are of key importance for floral signaling. Our observations confirmed a classical genetic prediction that s latifolia has three dispersed male-determining loci on the y chromosome, one for carpel suppression, one for early stamen development, and another for late stamen development.
Twelve individuals of the plant silene latifolia (white campion) were used for this study: one male parent (individual number sa984), one female parent (individual number sa985) and 10 f1 progeny (4 males, 6 females) from the sa984 x sa985 cross all individuals were grown in the glasshouse at the university of oxford (department of plant sciences. White campion, silene latifolia (caryophyllaceae), emits a diverse array of volatiles to attract sphingid, geometrid, and noctuid moths for pollination [1 – 4] this species also shows a pronounced day-night rhythm in odor emission, with the key compounds predominately emitted during the night [ 4 – 7 . Silene latifolia (formerly melandrium album), the white campion is a dioecious flowering plant in the family caryophyllaceae, native to most of europe, western asia and northern africa it is a herbaceous annual , occasionally biennial or a short-lived perennial plant , growing to between 40–80 centimetres tall.
In some unisexual plants, such as maize and silene latifolia (white campion), genetic sex determination is generally achieved by sex chromosomes, where males and females differ in the composition of one chromosome pair smeekens et al cloned and sequenced a cdna for plastocyanin from silene pratensis (white campion) and identified an n. 9 silene latifolia poir ssp alba (p mill) greuter & burdet e white campion lychnis alba p mill melandrium album (p mill) garcke silene alba (p mill) krause s pratensis (raf) godr & gren • ct, ma, me, nh, ri, vt fields, roadsides, waste areas, areas of cultivation 7×9.

Silene latifolia is the currently accepted latin name for white campion however, some recent literature refers to this species as silene alba, and older literature refers to it as lychnis alba or melindrum seeds mature in mid to late summer depending upon the latitude each fruit produces over 200 seeds, and 80 to 90 percent of seeds germinate. Identification of white campion (silene latifolia) guaiacol o-methyltransferase involved in the biosynthesis of veratrole, a key volatile for pollinator attraction alok k gupta 1 , 2 email author , tariq a akhtar 3 . The dioecious white campion silene latifolia (syn melandrium album) has heteromorphic sex chromosomes, xx in females and xy in males, that are larger than the autosomes and enable their separation by flow sorting the group of mros genes, the first male-specifically expressed genes in dioecious plants, was recently identified in s latifolia. Mapping of sex determination loci on the white campion (silene latifolia)y chromosome using ampliﬁed fragment length polymorphism sabine lebel-hardenack, elizabeth hauser, † teresa f law.
The white campion’s masculinity crisis the y chromosome of the white campion (silene latifolia) has undergone genetic degradation, losing some genes entirely from its y chromosome charlotte gardener, danielle hewson, abbie o’connor, francis windram this year, bergero et al. The sex chromosomes of dioecious white campion, silene latifolia (caryophyllaceae), are of relatively recent origin (10–20 million years), providing a unique opportunity to trace the origin and evolution of sex chromosomes in this genus by comparing closely related silene species with and without sex chromosomes.
Older taxonomic treatments place s latifolia subsp alba in the genus lychnis, which differs from silene in very small structural details of the flowers however, robinson and fernald (1908) record both l alba and s latifolia, while other botanists record this species as s alba.
