first report of Raceme blight caused by cladosporium cladosporioides on macadamia nuts in south africa
Plant Disease, 2008Co-Authors: N Van Den Berg, S Serfontein, B Christie, C MunroAbstract:In September of 2005 and 2006, macadamia (Macadamia integrifolia Maiden & Betche) orchards in Tzaneen, Modjadji, Politsi, and Levubu in the Northern Province and Kiepersol in Mpumalanga, South Africa were surveyed and sampled to determine the causal agent of Raceme blight. Symptoms appeared during early bloom and were present on Racemes of all developmental stages. Early signs were necrotic tips of the peduncle that often curved to one side with necrosis spreading upward, resulting in the so-called “rat tail”. Unopened flowers were also affected. In severe cases, the entire inflorescence (flowers and peduncle) was necrotic and eventually flowers abscised. Occasionally, infection began with single flowers as small water-soaked specks on the flower, with no symptoms on the green peduncle. Diseased Racemes were covered with olive gray patches of mycelia and abundant conidia. Flowers with blight symptoms were collected, surface disinfested with 70% ethanol for 2 min, and left to dry. Thirty isolations were ma...

changes in soybean Raceme and petiole anatomy induced by 6 benzylaminopurine
Annals of Botany, 1991Co-Authors: Anxiu Kuang, Curt M Peterson, Roland R DuteAbstract:Our purpose was to determine the cellular changes that occured in the rachis of terminal Racemes and the petiole of the uppermost mainstem leaf following BAP treatment.

expression of vegetative storage protein vsp β in soybean Raceme tissues in response to flowers set
Journal of Experimental Botany, 1995Co-Authors: R N Reese, C D Dybing, C A White, C A Page, J E LarsonAbstract:Abortion of flowers and pods (>25%) appears to be part of the normal developmental sequence in Glycine max [L.] Merr. Slow growth rates of seeds and pods, and development of an abscission zone in Raceme tissues subtending flowers destined to abort contribute to this loss, but the processes leading to these events have not been elucidated. Rescue of soybean flowers destined to abort was accomplished by removal of proximal flowers and/or application of 1 mM benzyladenine (BA) before anthesis. Raceme tissues (axes and pedicels, including the abscission zone) subtending setting and aborting flowers were examined for differential protein expression to identify gene products that were directly associated with the induction of flower set. Induction to set was associated with increased protein concentrations. Transcription and translation of a soybean vegetative storage protein (VSP-β) in the subtending Raceme tissues was directly linked to flower set. Cytokinin application increased growth of Raceme tissues independent of fruit set. A model system for future studies of regulation of soybean flower set and abortion is presented.

plant associated and soil microbiota composition as a novel criterion for the environmental risk assessment of genetically modified plants
GM crops & food, 2020Co-Authors: Astghik Z Pepoyan, Michael L. ChikindasAbstract:The impact of genetically modified plants on plant-associated and surrounding soil microorganisms is an uninvestigated area of environmental risk assessment. Biological markers such as lysine racem...
