Physiological mechanism of tolerance of Lycopersicon spp. exposed to salt stress
Canadian Journal of Plant Science, 2000 The physiological mechanism of salt tolerance in Lycopersicon spp. was investigated. Ten Lycopersicon spp. were exposed to a gradual NaCl-induced decline in root zone water potential of −0.10 MPa d−1 for 10 d and maintained at −1.065 MPa (221.4 mM NaCl) for a period of 20 d. Growth, water relations and accumulation of ions and compatible solutes, such

MOLECULAR MARKERS AND GENETIC BASE BROADENING IN LYCOPERSICON SPP.
Acta Horticulturae, 2001Genetic variability utilised in modern crops is limited because of bottlenecks produced during the domestication process, breeding new cultivars outside the native region and past selection pressures. Tomato (Lycopersicon esculentum L.) is one of many autogamous crop species in which germplasm has been severely reduced by these processes.

Protoplast fusion experiments between Lycopersicon esculentum or L. peruvianum and Nicotiana tabacum or N. plumbaginifolia were performed to investigate the possibility of producing symmetric and asymmetric somatic hybrids between these genera. These fusions, which involved 1.7 x 10(8) protoplasts, yielded 35 viable hybrid calli. Plant regeneration was

The Inheritance of Chilling Tolerance in Tomato (Lycopersicon spp.)
Plant Biology, 2005During the past 25 years, chilling tolerance of the cultivated (chilling-sensitive) tomato Lycopersicon esculentum and its wild, chilling-tolerant relatives L. peruvianum and L. hirsutum (and, less intensively studied, L. chilense) has been the object of several investigations.

Response of Pratylenchus spp Infected Tomato (Lycopersicon esculentum Mill) to Organic Compounds from Mangifera indica [PDF]
, 2015 The need to reduce the negative impact of synthetic nematicides on the environment necessitated the search for bio-pesticides. This study was conducted to evaluate the nematicidal potential of chromatographic fractions from Mangifera indica on tomato in the screenhouse and field. M. indica bark was extracted with ethanol (EtOH) and dichloromethane (DCM)

, 2002 Resistance against both Potato virus Y (PVY) and Tobacco etch virus (TEV) was identified in the wild tomato relative Lycopersicon hirsutum PI247087. Analysis of the segregation ratio in F2/F3 and BC1 interspecific progenies indicated that a single recessive gene or two very tightly linked recessive loci are involved in resistance to both potyviruses ...

Herpetomonas spp. isolated from tomato fruits (Lycopersicon esculentum) in southern Spain [PDF]
Experimental Parasitology, 2007 A flagellate of the family Trypanosomatidae was isolated from fruits of Lycopersicon esculentum (tomato) in southeastern Spain. The isolate was successfully adapted to in vitro culture in monophasic media. The morphology showed the kinetoplast to be positioned towards the middle of the body, and the typical opistomastigote form characteristic of ...

Accessions of Lycopersicon chilense, L. peruvianum, L.hirsutum and sixteen L. esculentum genotypes were evaluated undergreenhouse conditions for resistance to a whitefly-transmitted geminivirusisolate from Brasilia-DF (DF1). Artificial cage inoculation oftomato plants at the two true-leaf stage, using 20 viruliferous whiteflies perplant in individual ...
