Absorption of selenium by Lactuca sativa as affected by carboxymethylcellulose
Chemosphere, 2007Several organic compounds of high molecular weight present in soil interact with selenium and may act as active binding agents affecting its availability in soil, and, consequently, selenium uptake by plants. This study is aimed at investigating the effects of polysaccharides on selenium speciation in soil and on selenium absorption by Lactuca sativa L.

Infrequent transposition of Ac in lettuce, Lactuca sativa
Plant Molecular Biology, 1993The maize transposable element Activator (Ac) is being used to develop a transposon mutagenesis system in lettuce, Lactuca sativa. Two constructs containing the complete Ac from the waxy-m7 locus of maize were introduced into lettuce and monitored for activity using Southern analysis and PCR amplification of the excision site.

Microsatellite retrieval in lettuce (Lactuca sativa L.)
Genome, 1999By using enriched genomic libraries, microsatellite-containing sequences were isolated from lettuce (Lactuca sativa) with high efficiency. With this approach, a sizeable fraction (up to 55%) of the clones contained a microsatellite. In about half of these clones, primers could be designed for PCR amplification of the microsatellite.

STRUCTURE OF THE SHOOT APEX IN LACTUCA SATIVA
American Journal of Botany, 1966Histological observations of the leaf lettuce ‘Black Seeded Simpson’ showed the dormant embryo to possess two visible leaves and a flkat to slightly depressed plumular apex. Observations conducted over a 12‐day period of germination and growth showed the development of L 1 and L

Transactivation of Ds elements in plants of lettuce (Lactuca sativa)
Molecular and General Genetics MGG, 1993The maize transposable element, Activator (Ac), is being used to develop a transposon mutagenesis system in lettuce, Lactuca sativa. In this paper, we describe somatic and germinal transactivation of Ds by chimeric transposase genes in whole plants.

Methods in molecular biology (Clifton, N.J.), 2006
Lettuce is a globally important leafy vegetable with the United States being the largest world producers. The crop is susceptible to a number of viruses that are aphid transmitted and also highly vulnerable to post harvest diseases. Although wild species of lettuce are an important source of disease resistance genes, their introgression into commercial

Development of Stomata in Lactuca sativa L.
Annals of Botany, 1972The structure of the epidermis on various parts of the plant of Lactuca sativa Linn. is described. Development of stomata is studied in young leaves and stems. Tognini (1897) has previously mentioned that the stomata on stems of L. virosa develop from a meristemoid with four cutting faces but the present study points out that the meristemoid cuts off ...

Sesquiterpene lactones from Lactuca sativa
Phytochemistry, 1986Abstract The aerial parts of Lactuca sativa afforded lactucin, 1 11β,13-dihydrolactucin, lactupicrin, a new melampolide and 3β,14-dihydroxy-11β,13-dihydrocostunolide.

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.
