EMBRYO RESCUE OF SOLANUM LYCOPERSICUM × S. PERUVIANUM TOMATO CROSS FOR TOCV RESISTANCE

Acta Horticulturae, 2012
The tomato line 'EELM-802' shows strong resistance to Tomato chlorosis virus (ToCV). Attempts to cross this line with a susceptible parent in order to study genetics of the resistance have failed. 'EELM-802' was derived by selfing and selection from 'IAC-CN-RT', a population obtained by embryo rescue in Brazil from a cross between the cultivated tomato

АКТИВНЫЕ РЕТРОТРАНСПОЗОНЫ SOLANUM PERUVIANUM, ИНТРОГРЕССИРОВАННЫЕ В ГЕНОМ ТОМАТА (S. LYCOPERSICUM L.)

Биотехнология в растениеводстве, животноводстве и сельскохозяйственной микробиологии, 2023
Геном большинства сельскохозяйственных растений в значительной мере представлен мобильными элементами (МЭ, транспозоны), способными к перемещению и пролиферации внутри генома, что также может приводить к появлению генов нового функционального значения.

Obtaining advanced generations from Solanum peruvianum PI 126944 in the genetic background of S. lycopersicum by immature seed culture

Euphytica, 2017
The accession Solanum peruvianum PI 126944 has been reported as resistant to different biotic and abiotic stresses. In previous works of the group, advanced generations were derived from two interspecific hybrids, including up to pseudo-F6 generations and backcrosses to the cultivated species of some of the pseudo-Fn generations.

Fine mapping of the nematode resistance gene Mi-3 in Solanum peruvianum and construction of a S. lycopersicum DNA contig spanning the locus

Molecular Genetics and Genomics, 2005
Currently, the only genetic resistance against root-knot nematodes in the cultivated tomato Solanum lycopersicum (Lycopersicon esculentum) is due to the gene Mi-1. Another resistance gene, Mi-3, identified in the related wild species Solanum peruvianum (Lycopersicon peruvianum) confers resistance to nematodes that are virulent on tomato lines that ...

Chemical profiling and separation of bioactive secondary metabolites in Maca (Lepidium peruvianum) by normal and reverse phase thin layer chromatography coupled to desorption electrospray ionization-mass spectrometry.

Journal of Mass Spectrometry, 2020
Maca is a Peruvian tuberous root of the Brassicaceae family grown in the central Andes between altitudes of 4000 and 4500 m. The medicinal plant is a nutraceutical with important biological activities and health effects.

Sequence of an S-protein of Lycopersicon peruvianum and comparison with other solanaceous S-proteins

Sexual Plant Reproduction, 1992
cDNA clones for an S-allele, designated S5, of the self-incompatibility locus (S-locus) of Lycopersicon peruvianum have been isolated by probing a pistil cDNA library with cDNAs for S-alleles of Petunia inflata and Solanum chacoense. The longest S5-cDNA is 869 bp and contains an open reading frame of 217 amino acids.

The generation of new S alleles at the incompatibility locus of Lycopersicum peruvianum Mill

Theoretical and Applied Genetics, 1971
A detailed analysis has been made of S genotypes in progenies derived from induced and spontaneous inbreeding processes in a clonal population of Lycopersicum peruvianum Mill. The results indicate that, in certain genetic backgrounds, induced inbreeding leads to the generation of a new S allele which usually first appears in the pistil of individuals ...

Pollen-expressed S-RNases are not involved in self-incompatibility in Lycopersicon peruvianum

Sexual Plant Reproduction, 1999
Self-incompatibility in solanaceous plants is gametophytically controlled by a multiallelic S-locus. The only known S-locus product is a series of extracellular ribonucleases (the S-RNases) which are expressed in the mature style and determine its self-incompatibility phenotype. Potentially, S-RNases also determine the self-incompatibility phenotype of

Molecular diversity of three S-allele cDNAs associated with gametophytic self-incompatibility in Lycopersicon peruvianum

Plant Molecular Biology, 1994
We isolated S allele-associated cDNA clones from each of the stylar cDNA libraries of Lycopersicon peruvianum of two different S genotypes (S12Sb and S13Sc) with S11Sa allele-associated cDNA (LPS11) as a probe. The longest cDNA clones, designated LPS12 and LPS13, which were 779 bp and 853 bp in length, contained open reading frames of 189 and 210 amino

Self-compatibility in aLycopersicon peruvianum variant (LA2157) is associated with a lack of style S-RNase activity

Theoretical and Applied Genetics, 1994
A series of crosses between a naturally-occurring self-compatible accession ofLycopersicon peruvianum and a closely-related self-incompatible accession were used to demonstrate that the mutation to self-compatibility is located at the S-locus. Progeny of the crosses contain abundant style proteins of about 30 kDa that segregate with the S6and S7 ...
