Alterations of the manifestations of hybrid breakdown in Lycopersicon esculentum L. pennellii F 2 populations containing L. esculentum versus L. pennellii cytoplasm [PDF]

Sexual Plant Reproduction, 1995
Reproductive abnormalities reduced the percent stainable pollen, and fruit and seed set in interspecific F2 populations derived from crosses of Lycopersicon esculentum and L. pennellii but were not observed in parental lines and interspecific F1 populations.

Seedling salt tolerance in tomato

, 2011
Soils with higher concentrations of salt are becoming more and more a constraint for many crops to obtain high yields. Wild tomato species, adapted to adverse environments, are a potential reservoir for genes underlying quantitative trait loci (QTL ...

Xv4-vrxv4: A New Gene-for-Gene Interaction Identified Between Xanthomonas campestris pv. Vesicatoria Race T3 and the Wild Tomato Relative Lycopersicon pennellii

Molecular Plant-Microbe Interactions, 2000
Strains of tomato race 3 (T3) of Xanthomonas campestris pv. vesicatoria elicit a hypersensitive response (HR) in leaves of Lycopersicon pennellii LA716.

Meiosis in hybrids between Lycopersicon esculentum and Solanum pennellii

, 1963
Meiotic chromosome cytology was compared between Solanum pennellii, Lycopersicon esculentum, and the F1 hybrid. Pachytene chromosomes are very similar in gross morphology, but several of the S.

Herança de acilaçúcares em genótipos de tomateiro provenientes de cruzamento interespecífico Inheritance of tomato leaflet acylsugar contents in genotypes derived from an interspecific cross

Pesquisa Agropecuária Brasileira, 2007
O objetivo deste trabalho foi determinar a herança da produção de acilaçúcares em genótipos de tomateiro, em uma população segregante (F2) do terceiro retrocruzamento, para Lycopersicon esculentum Mill. 'TOM-584', a partir da espécie L. pennellii 'LA-716'

Identification and mapping of quantitative resistance to late blight (Phytophthora infestans) in Solanum habrochaites LA1777

, 2011
Late blight (Phytophthora infestans) can have devastating effects on tomato production over the whole world. Most of the commercial cultivars of tomato, Solanum lycopersicum, are susceptible.

Genetic Mapping of Ph-2, a Single Locus Controlling Partial Resistance to Phytophthora infestans in Tomato

Molecular Plant-Microbe Interactions, 1998
Late blight caused by the fungal pathogen Phytophthora infestans is one of the most important diseases of potato (Solanum tuberosum) and tomato (Lycopersicon esculentum).

Salt stress-induced alterations in proline accumulation, relative water content and superoxide dismutase (SOD) activity in salt sensitive Lycopersicon esculentum and salt-tolerant L. pennellii

, 2005
Plants exposed to stress undergo changes in their metabolism in order to adapt with the changes in their environment. Salt stress has been attributed to some physiological and biochemical alterations in plants. Proline accumulation relative water content

Evidence of cryptic introgression in tomato (Solanum lycopersicum L.) based on wild tomato species alleles

BMC Plant Biology, 2012
Background Many highly beneficial traits (e.g. disease or abiotic stress resistance) have been transferred into crops through crosses with their wild relatives.
