Phytophthora infestans, the causal agent of late blight is the most devastating pathogen of cultivated potato worldwide. Utilizing map based cloning; a genomic region containing a cluster of six nucleotide binding site-leucine-rich repeat resistance gene analogs was isolated from the wild potato species Solanum bulbocastanum. Four genes were pseudogenes, with coding sequences interrupted by either frame shift mutations or premature stop codons. However, neither of the two uninterrupted genes conferred resistance to P. infestans when introduced into susceptible potatoes. Specific primers for one of the pseudogenes were used to amplify an uninterrupted cDNA from P. infestans-infected S. bulbocastanum leaves. A corresponding gDNA was amplified from a late blight-resistant bulbocastanum-tuberosum introgression line (Rpi-bt1). The Rpi-bt1 gene under transcriptional control of the constitutive potato Ubi3 promoter was found to confer resistance to P. infestans in several transgenic potato lines in a whole plant greenhouse assay.Resumen Phytophthora infestans, el agente causal del tizón tardío, es el patógeno mas devastador de la papa cultivada en el mundo. Mediante la clonación basada en mapas, se aisló de la especie silvestre de papa Solanum bulbocastanum una región genómica que incluía un grupo de repetición con seis análogos de genes de resistencia de sitios de unión de nucleótidos ricos en leucina. Cuatro genes fueron pseudogenes, con secuencias de codificación interrumpidas ya fuera por mutaciones por cambio de marcos o por codones de terminación prematura. No obstante, ninguno de los dos genes sin interrupción confirió resistencia a P. infestans cuando se introdujeron a papas susceptibles. Se utilizaron iniciadores específicos para uno de los pseudogenes para amplificar un ADNc ininterrumpido de hojas de S. bulbocastanum infectadas con P. infestans. También se amplificó un ADNg correspondiente de una línea de introgresión (Rpi-bt1) de bulbocastanumtuberosum resistente al tizón tardío. Se encontró que el gen Rpi-bt1 bajo control transcripcional del promotor de papa Ubi3 confiere resistencia a P. infestans en varias líneas de papa transgénica en un ensayo con planta completa bajo invernadero.

BACKGROUND:Recently, weather disasters such as hail and typhoon occur frequently. These threaten the stable cultivation of potatoes. It is very important to cultivate potatoes with stable under unexpected weather disasters. This study was performed to investigate the correlation between mophological characteristics of potato stem and its resistance to hail damage in different potato cultivars. METHODS AND RESULTS:Hail fall occurred for 8 minutes on May 31, 2012 in the field of Highland Agriculture Research Center located in Jinbu-myeon Gangwon-do. Potato crop grown in the field was affected by hail due to which the stems of potato were broken. The percentage of broken stem of potato was investigated as the level of damage by hail. To determine the difference in the

“…An effort was made to select clones that are familiar to the potato industry and that fall into welldefined maturity classes. However, conflicting maturity designations were reported for some cultivars [22][23][24][25]. In general, the cultivars fell into three maturity classes, defined as early-medium (Russet Norkotah and Atlantic), medium-late (Pike and C75-5 + 297), and late (Snowden and Russet Burbank).…”

Examination of Potential Measures of Vine Maturity in Potato

Plant maturity is a complex physiological trait routinely evaluated by plant breeders because of its agronomic, economic, and breeding implications. In potato, plant maturity is typically estimated by monitoring vine characteristics. This study investigates several reported measures of vine maturity in potato cultivars, including examination of flower development, leaf chlorophyll content, and leaf peroxidase activity to see what method is most appropriate for maturity classification in temperate production regions. These three measures were evaluated multiple times throughout a single growing season across two locations. The data were analyzed using canonical discriminant and dichotomous tree analyses. Both methods revealed that flower development is not an accurate indicator of maturity, even though it is a common component of maturity screening protocols. Peroxidase measures were slightly better, but the optimal period of time to assess this trait was variable across locations and a considerable time commitment is required to collect and process samples. Monitoring leaf chlorophyll content throughout plant development was most appropriate for predicting vine maturity under these conditions, as this trait showed the most consistency and greatest prediction accuracy (69% -71%) relative to peroxidase activity and flowering development. Additionally, chlorophyll measurements are a more practical method of measuring maturity due to the ease of data collection. Leaf chlorophyll content best distinguished late cultivars from early-medium and medium-late cultivars. However, it did not separate early-medium from mediumlate cultivars. Combining chlorophyll monitoring with peroxidase and flowering measures improved the ability to distinguish among the early-medium and medium-late maturity classes. However, doing so only increased classification accuracy by 3%.
