In Vitro Function of S RNases in Lycopersicon peruvianum

open access: yesMolecules and Cells, 2001
S RNases are products of the S locus that are expressed in the stylar tissue of Lycopersicon peruvianum with the gametophytic self-incompatibility (SI) system. Two S RNases (S12 and Sa) with RNase activity from the S12Sa genotype of L. peruvianum were purified using gel filtration and cation-exchange chromatography.

Development of a locus-specific, co-dominant SCAR marker for assisted-selection of the Sw-5 (Tospovirus resistance) gene cluster in a wide range of tomato accessions [PDF]

open access: yes, 2010
The best levels of broad-spectrum Tospovirus resistance reported in tomatoes thus far are conferred by the Sw-5 locus. This locus contains at least five paralogues (denoted Sw-5a through Sw-5e), of which Sw-5b represents the actual resistance gene.

Guidelines to use tomato in experiments with a controlled environment [PDF]

open access: yes, 2014
Domesticated tomato (Solanum lycopersicum) is the most important horticultural crop worldwide. Low polymorphism at the DNA level conflicts with the wealth of morphological variation. Fruits vary widely in size, shape, and color.

Balancing Selection at the Tomato RCR3 Guardee Gene Family Maintains Variation in Strength of Pathogen Defense [PDF]

open access: yes, 2012
Coevolution between hosts and pathogens is thought to occur between interacting molecules of both species. This results in the maintenance of genetic diversity at pathogen antigens (or so-called effectors) and host resistance genes such as the major ...

PERICLINAL CHIMERAS COMPOSED OF LYCOPERSICON PERUVIANUM AND L. ESCULENTUM DEMONSTRATE THAT S-LOCUS ASSOCIATED PROTEINS AND SELF-INCOMPATIBILITY CAN BE UNCOUPLED [PDF]

open access: yesHortScience, 1995
Lycopersicon peruvianum is a wild species of tomato that exhibits gametophytic self-incompatibility (S), wherein the SI response is controlled by the genotype of the pollen. Cultivated tomato (L. esculentum) is a self-compatible species. Assisted by phenotypic markers, periclinal graft chimeras between these two species have been obtained.

Fitness effects of derived deleterious mutations in four closely related wild tomato species with spatial structure [PDF]

open access: yes, 2011
A key issue in evolutionary biology is an improved understanding of the genetic mechanisms by which species adapt to various environments. Using DNA sequence data, it is possible to quantify the number of adaptive and deleterious mutations, and the ...

Scion and Rootstock Differently Influence Growth, Yield and Quality Characteristics of Cherry Tomato

open access: yesPlants, 2020
Grafting is a valuable tool for managing problems of tomato soil-borne pathogens and pests, but often generates unpredictable effects on crop yield and product quality.

Edaphoclimatic Descriptors of Wild Tomato Species (Solanum Sect. Lycopersicon) and Closely Related Species (Solanum Sect. Juglandifolia and Sect. Lycopersicoides) in South America

open access: yesFrontiers in Genetics, 2021
Wild species related to cultivated tomato are essential genetic resources in breeding programs focused on food security to face future challenges. The ecogeographic analysis allows identifying the species adaptive ranges and most relevant environmental ...

Effects of Alternaria alternata f.sp. lycopersici toxins on pollen [PDF]

open access: yes, 1988
Effects of the phytotoxic compounds (AAL-toxins) isolated from cell-free culture filtrates of Alternaria alternata f.sp. lycopersici on in vitro pollen development were studied. AAL-toxins inhibited both germination and tube growth of pollen from several
