Specificity of Bremia lactucae from Lactuca sativa

Transactions of the British Mycological Society, 1977
Bremia lactucae Regel isolates from Lactuca sativa L. were capable of extensively invading only closely related wild species belonging to the same subsection of the genus as the original host (i.e. Lactuca serriola L., L. virosa L., L. saligna L. and variants of these species).

Resistance in lactuca against Bremia lactucae Regel

Euphytica, 1974
After testing many Lactuca species consisting of cultivated types and wild species, 23 PIVT numbers (all accessions of wild species) were found to have resistance to the five NL races of Bremia lactucaeRegel.

Response of differential cultivars of Lactuca sativa to Bremia lactucae isolates from Lactuca serriola

Transactions of the British Mycological Society, 1984
Eight isolates of Bremia lactucae from Lactuca serriola were tested for pathogenicity on 29 differential cultivars of Lactuca sativa and one L. sativa × L. serriola hybrid. The cultivars carried fourteen known race specific resistance factors (R1–R14) both singly and in combination, plus RO in Cobham Green.

Characterization and identification of Lactuca sativa cultivars and wild relatives with SDS-electrophoresis (Lactuca sect. Lactuca, Compositae)

Genetic Resources and Crop Evolution, 1996
Patterns of achene proteins of L. sativa cultivars are mutually compared and compared with L. saligna, L. serriola and L. virosa. L. virosa and L. saligna are easy to identify and are characterized by typical banding patterns. L. sativa and L. serriola share the same banding pattern. They differ clearly from L. saligna and L. virosa. L.

Sesquiterpenoids from Lactuca tatarica

Fitoterapia, 2010
A new guaianolide and a new eudesmanolide were isolated from Lactuca tatarica, as well as eight known sesquiterpenoids. The new compounds were elucidated on the basis of spectroscopic methods including IR, HRESIMS, 1D and 2D NMR, and the known compounds were established by comparing their physical data with those of the corresponding compounds in the ...

The behaviour of Bretnia lactucae on cultivars of Lactuca sativa and on other composites

Annals of Applied Biology, 1976
SUMMARYThe spores of an isolate of Bremia lactucae obtained from lettuce germinated equally well on Cellophane and on the surfaces of all plant species inoculated. The fungus penetrated the epidermal cells of both host and non‐host plants but extensively invaded only certain lettuce cultivars.

New sources of major gene resistance in Lactuca to Bremia lactucae

Euphytica, 1991
A total of 1789 accessions of several lettuce collections was screened to find new major gene resistance to the downy mildew fungus Bremia lactucae Regel. The accessions belonged to the species Lactuca sativa (N=1288), L. serriola (N=399), L. saligna (N=52) and L. virosa (N=50). A total of 20 races of B.

The effects of chloramphenicol on Ulva lactuca

Chemosphere, 2013
The administration of pharmacological substances in the food producing industry is a crucial and long established practice in ensuring animal welfare. However, a very high percentage of the drugs used will directly or indirectly be present in the various compartments of natural ecosystems therefore constituting a source of pollution. The reactions that
