Abstract The unique life form of plants promotes the accumulation somatic mutations that can be passed to offspring in next generation, because same meristem cells responsible for vegetative growth also generate gametes sexual reproduction. However, little is known about consequences mutation fitness. We evaluate fitness effects Mimulus guttatus by comparing progeny from self-pollinations made ...

The mutant Paramecium tetraurelia cell line d48 is unable to express the serotype A protein on its surface. Although the A gene is intact in the micronuclei of d48, the A gene copies in the macronucleus contain a large deletion eliminating virtually the entire coding sequence. Previous studies showed that microinjection of a plasmid containing the entire A gene into the macronucleus of d48 perm...

Introduction In Tunisia the genus Lathyrus is represented by 15 native species , distributed essentially in marginal environments in the north of the country. Many of them are of considerable agronomic interest as forage (L. ochrus and L. articulatus) and as human food (L. cicera and L. sativus). These species are under utilised and in the past little effort has been made to expand the selectio...

The Paramecium tetraurelia mutant called d48 has a complete copy of the A surface protein gene in its micronuclei, but lacks the A gene in the macronucleus. Previous experiments have shown that microinjection of a plasmid containing the entire A gene or a large portion of the gene into the macronucleus of d48 rescued the cell line after formation of a new macronucleus (autogamy). Here we show t...

Background: Argemone ochroleuca is a worldwide invasive weed but also highly valuable for their chemical compounds. Knowledge about its reproduction will help create plans control or propagation.
 Questions: Does A. has an incompatibility system like other Papaveraceae species? Which are the reproductive strategies that favor seed formation in ?
 Studied species: annual species with b...
