1. Heritability of resistance to potato late blight in an F1 population of elite potato cultivars
ABSTRACT Phytophthora infestans is the most important disease in potato crops. Its control is based on the use of chemical products that have developed pathogen resistance and high economic and environmental impacts. To reduce these effects, the use of plant varieties or cultivars resistant to this pathogen has been proposed. The aim of this study was to eva

2. Atividade antimicrobiana de metabólitos extracelulares das bactérias antagonistas isoladas de cultivos de batata (Solanum phureja)
Os microorganismos biocontroladores têm capacidade de produzir compostos ativos que inibem o desenvolvimento de fitopatógenos, constituindo-se em uma ferramenta promissora para a obtenção de princípios ativos que substituem os pesticidas de sínteses. No presente trabalho, avaliou-se a capacidade de um conjunto de gentes com potencial biocontrolador, pa

3. Uso de esquejes de tallo lateral para evaluar la resistencia de genotipos de Solanum phureja a Spongospora subterranea f. sp. subterranea
In order to evaluate the resistance to Spongospora subterranea f. sp. subterranea on 105 genotypes of Solanum phureja (local name in Colombia papa criolla), bioassays were conducted through propagation by lateral stem cuttings. Inoculation was performed with a 1 x 10(6) sporeballs mL-1 solution. The level of resistance or susceptibility of each genotype to t

4. Herdabilidade do conteúdo de proteína total em batata diplóide Solanum tuberosum grupo Phureja
Nos últimos anos, pesquisas básicas de genética que ajudem no estabelecimento de programas de melhoramento de plantas visando à qualidade nutricional da batata têm tido muita importância. Solanum tuberosum Grupo Phureja é uma espécie que tem potencialidade para a exportação, além de características superiores quando comparadas com espécies de ou

5. Substâncias com atividade citocinínica estimulam a brotação de gemas em tubérculos de batata
Antes de iniciar a brotação, o tubérculo de batata passa por um período de dormência característico de cada genótipo. Quando as condições são favoráveis à tuberização, o crescimento longitudinal do estolão é interrompido e se inicia o espessamento da região subapical entre a penúltima e a última gema. Entre os fatores envolvidos nesse proc

6. Pólen 2n e mecanismos meióticos de formação em Solanum commersonii ssp
Solanum commersonii subsp. commersonii Dun. e Solanum commersonii subsp. malmeanum Bitt. (2n=2x=24 - 1EBN) não podem ser diretamente cruzadas com a batata cultivada de S. tuberosum subsp. tuberosum L. (2n=4x=48 -4 EBN) em razão da barreira da ploidia e do número de equilíbrio do endosperma (EBN). No entanto, a produção de pólen não reduzido por S. co

7. Genetic Analysis of Isozyme Variants in Diploid and Tetraploid Potatoes
Genetic segregations for six enzyme-coding genes were studied in diploid and tetraploid progenies obtained from various Solanum species. The loci identified are Prx-2, Prx-3, Prx-5, Mdh-1, Pgi-1 and Sdh-1. Prx-2 and Prx-3 were found to be linked; alleles at these loci segregated concomitantly in most of the diploid progenies. The putative homologous loci in

8. Comparison of Tuber Proteomes of Potato Varieties, Landraces, and Genetically Modified Lines1
Crop improvement by genetic modification remains controversial, one of the major issues being the potential for unintended effects. Comparative safety assessment includes targeted analysis of key nutrients and antinutritional factors, but broader scale-profiling or “omics” methods could increase the chances of detecting unintended effects. Comparative as

9. Localized Wounding by Heat Initiates the Accumulation of Proteinase Inhibitor II in Abscisic Acid-Deficient Plants by Triggering Jasmonic Acid Biosynthesis.
To test whether the response to electrical current and heat treatment is due to the same signaling pathway that mediates mechanical wounding, we analyzed the effect of electric-current application and localized burning on proteinase inhibitor II (Pin2) gene expression in both wild-type and abscisic acid (ABA)-deficient tomato (Lycopersicon esculentum Mill.)

10. Abscisic Acid Mediates Wound Induction but Not Developmental-Specific Expression of the Proteinase Inhibitor II Gene Family.
The expression of the potato and tomato proteinase inhibitor II (pin2) gene family is subject to both developmental and environmental control, being constitutively expressed in potato tubers while only being present in the foliage of the potato or tomato plants after mechanical damage. There is evidence that the phytohormone abscisic acid (ABA) is involved i

11. RFLP Maps Based on a Common Set of Clones Reveal Modes of Chromosomal Evolution in Potato and Tomato
Potato (Solanum tuberosum L.) and tomato (Lycopersicon esculentum) are members of the Solanaceae (nightshade family) and have the same basic chromosome number (x = 12). However, they cannot be cross-hybridized and, until now, it was unknown how conserved the gene order might be between these two species. We report herein the construction of a genetic linkage
