“…This mechanism might play a role in the rapid "chemical desiccation" used in the evaluation of drought resistance in plant breeding, to simulate natural drought (Blum et al 1983;Nicolas and Turner 1993;Burkhardt 2010), and in the rapid defoliation of crops such as potato and cotton to facilitate harvest. The technique works better with chaotropic than with kosmotropic ions (Wilson et al 1947;Herrett et al 1962;Murphy 1968;Renner 1991;Bond and Bollich 2007;Burkhardt et al 2012).…”

“…While some of these disorders are clearly non-pathologic or 'physiological', many have been positively linked to pathogens, including late blight (Phytophthora infestans) (Levin et al 2001), potato soft rot (Erwinia carotovora pv. atroseptica) (Ghanekar et al 1984;Nourian et al 2002), potato leaf roll virus 'net necrosis' (Murphy 1968), potato virus Y (PVY) (HinrichsBerger et al 1999), potato virus X (PVX) (Mondy and Kock 1978;Cruz and Baulcombe 1993), and common scab (Streptomyces scabies) (Blaszczak et al 2005). The end result of the above-mentioned diseases is the rendering of the tuber unusable as food or as seed for future plantings.…”

Evidence that Cell Death is Associated with Zebra Chip Disease in Potato Tubers

Zebra chip (ZC) is an established and highly destructive disease of potato (Solanum tuberosum L.) that occurs in several southwestern states of the United States, Mexico, Central America, and New Zealand. The causal agent for this disease has not been identified. However, the bacterium "Candidatus Liberibacter solanacearum" and the potato psyllid, Bactericera cockerelli (Šulc), its insect vector, are associated with the disease. Tubers from ZCaffected potato plants exhibit dramatic browning of vascular tissue concomitant with "necrotic flecking" both of which can affect the entire tuber. Upon frying, these tubers develop a characteristic striped pattern of discoloration rendering them unmarketable. These characteristic ZC symptoms in the tubers have been suggested to be associated with general cell death, though no evidence to confirm this hypothesis has been shown. In order to determine if cell death is associated with ZC disease, a series of experiments were undertaken. Cell death was initially quantified by comparing cellular ion leakage from ZC-affected and ZC-free tubers. Levels of ion leakage were found to be significantly higher in ZC-affected tubers compared to ZC-free tubers. To examine further the association of cell death with ZC disease, ZC-affected and ZC-free tubers were compared using classical histochemical staining methods in conjunction with optical microscopy, which revealed layers of dead cells surrounding numerous, small, irregularly-shaped lesions throughout the parenchymatic medullary region, vascular ring and cortex of ZC-affected tubers. This cell death was confirmed using high-resolution, field-emission scanning electron microscopy (FE-SEM) of fresh-cut tuber tissue.Resumen Zebra chip (ZC) es una enfermedad establecida y altamente destructiva de papa (Solanum tuberosum L.) que se presenta en varios estados del suroeste de los Estados Unidos, México, América Central y Nueva Zelandia. El agente causal de esta enfermedad no ha sido identificado. No obstante, la bacteria "Candidatus Liberibacter solanacearum" y el psílido de la papa Bactericera cockerelli (Šulc), su insecto vector, están asociados con la enfermedad. Los tubérculos de plantas afectadas por ZC presentan oscurecimiento dramático del tejido vascular concomitante con "pecas necróticas" que en ambos casos pueden afectar al tubérculo completo. Al freírse, estos tubérculos desarrollan un patrón característico de rayado haciéndolos no comerciales. Se ha sugerido que estos síntomas característicos en los tubérculos estén asociados con muerte general de las células, aún cuando no se ha mostrado evidencia para confirmar esta hipótesis. Se llevaron a cabo varios experimentos a fin de determinar si la muerte de las células está asociada con la enfermedad de ZC. La muerte celular se cuantificó inicialmente comparando el lixiviado iónico celular de tubérculos con y sin ZC. Se encontró que los niveles de iones lixiviados fueron significativamente más altos en tubérculos afectados con ZC comparados con los libres de ZC. Para examinar mas la a...

“…The resistance to excoriation of the periderm is a measure of skin set or physical maturity (Halderson and Henning 1993;Lulai and Orr 1994), and tuber sucrose content is used to quantify chemical maturity (Sowokinos 1978). In many potato production regions, vine maturity and physical maturity are encouraged by application of non-selective herbicides that cause vine desiccation and promote maturation of the periderm (Kempenaar and Struik 2007;Murphy 1968). Chemical maturity has proven to be a useful measure that predicts the potential for longterm storage of chipping potatoes (Sowokinos 1978), but has not proved to be a reliable measure for Russet Burbank and other processing russets (Sabba et al 2007).…”

Vine-Kill Treatment and Harvest Date have Persistent Effects on Tuber Physiology

The quality of potato (Solanum tuberosum) tubers coming out of storage depends on the state of the tubers going into storage. Experiments determined the effects of vine-kill treatment and harvest date on the post-harvest physiology of potato tubers stored for up to 12 weeks. Potato cultivar Russet Burbank grown in central Wisconsin was harvested in late July when tubers were immature, in late August, and in early September after complete natural senescence of vines. Prior to the first two harvests, vines were either desiccated with diquat dibromide or were untreated. Data were collected at harvest and in storage for skin set, tuber respiration rate, and tuber sucrose, glucose, and fructose contents. Skin set at harvest was increased by use of the desiccant at the early harvest date, but not at the middle harvest date. Early harvest without vine kill resulted in elevated tuber bud-end glucose contents in storage. Early harvest with vine kill treatment resulted in increased rates of respiration in storage that persisted through December. Neither tuber sucrose nor glucose content 6 weeks after harvest was a good predictor of tuber glucose content 12 weeks after harvest. These data demonstrate that vine-kill treatment and tuber maturity at harvest have long-term effects on tuber quality.Resumen La calidad de los tubérculos de papa (Solanum tuberosum) saliendo del almacén, depende de la condición de los tubérculos cuando entran. Los experimentos determinaron los efectos del tratamiento para eliminación del follaje y fecha de cosecha en la fisiología de post-cosecha de tubérculos de papa almacenados hasta por 12 semanas. El cultivar Russet Burbank cultivado en la parte central de Wisconsin se cosechó a finales de julio, cuando los tubérculos eran inmaduros, a finales de agosto, y al principio de septiembre, después de completar la senescencia natural del follaje. Antes de las primeras dos cosechas, el follaje se desecó con dibromuro de diquat o sin desecante. Se tomaron datos a la cosecha y en el almacén para madurez de la piel, nivel respiratorio del tubérculo, y para el contenido de sacarosa, glucosa y fructosa. La madurez de la piel se incrementó con el uso del desecante en la fecha temprana de cosecha, mas no en la intermedia. La cosecha temprana sin la eliminación del follaje dio por resultado un contenido elevado de glucosa en el extremo apical del tubérculo en almacén. La cosecha temprana con el tratamiento de eliminación del follaje resultó en niveles elevados de respiración en el almacén que persistieron hasta diciembre. Ni el contenido de la sacarosa ni el de glucosa del tubérculo, seis semanas después de la cosecha, fueron buenos indicadores del contenido de glucosa doce semanas después de la cosecha. Estos datos demuestran que el tratamiento de eliminación del follaje y la madurez del tubérculo a la cosecha, tienen efecto a largo plazo en la calidad del tubérculo.
