Vascular functioning and development of the kiwifruit berry (Actinidia deliciosa)
No full textThe aim of this study was to understand kiwifruit berry development and the role of cell turgor and the phloem unloading pathway in development. Important aspects of berry development include the size of the fruit and its composition. The fresh weight growth curve of the kiwifruit berry was shown to be double sigmoid in shape. Dry weight accumulated linearly for the initial 139 days after anthesis (DAA). At this time the soluble solids concentration began to increase. Berry firmness was measured using two methods, with the penetrometer and with a new non-destructive method, utilising skinfold callipers. Both methods exhibited similar results, indicating that the skin callipers may be useful in the future for non-destructive berry rheological measurements.
Cell turgor was measured indirectly from measurements of symplasmic and apoplasmic solute potentials, and the matric potential of the berry. Apoplasmic sap, required to measure the apoplasmic solute potential, was extracted using two different methods the pressure chamber and through centrifugation. Measurements of sap osmotic potential suggest that the sap extracted using the centrifuge was contaminated with symplasmic sap, resulting in a negative cell turgor estimate. However, the pressure chamber technique provided apoplasmic sap that produced a more accurate estimate of cell turgor. Direct estimates of cell turgor were only obtained from the midpoint of the growing season because of contamination with symplasmic sap, but the values obtained were comparable to literature values for developing grape and tomato berries.
The phloem unloading pathway in the fruit was investigated using a symplasmic tracer dye, carboxyfluorescein diacetate coupled with 14C labelling and autoradiography. The phloem unloading pathway was symplasmic until 91 DAA when the dye was restricted to the phloem cells only, indicating a change to an apoplasmic pathway. However, due to the lack of functional unloading seen in radiolabelled samples, a change in the phloem unloading pathway could not be confirmed

No full textPhotographic portrait of Daniel M. Berry, a pioneer of Pasadena, after 1873. Viewed from the chest up. He is wearing a bow tie, light-colored shirt, and dark jacket with wide lapels. He has a thick dark broad beard with moustache. His dark hair is parted on his left. He is turned slightly to his right. Berry was the first secretary of the original California Colony Association (of Indiana) and arrived in Pasadena 13 November 1873

The ripening wine grape berry skin transcriptome
No full textRipening of the grape berry immediately precedes harvesting and is the key phase which determines the composition of wine and table grapes. Although it is apparent that changes in gene expression levels play a role in initiating ripening, it is unknown to what extent gene expression levels differ between cultivars during ripening. We have undertaken a comparison of a selection of wine grape cultivars using a 9200 feature cDNA microarray to gauge the extent to which transcript levels differ between wine grape cultivars in the berry skin during ripening. Clones for microarray slide fabrication were sourced from a cDNA library constructed from mRNA derived from randomly sampled berries. The berries were collected at weekly intervals over four weeks of berry development including véraison. The microarray slides were hybridised with Cy3 and Cy5 labelled cDNA derived from the skin of ripening berries of the cultivars Cabernet Sauvignon, Pinot Noir, Shiraz, Chardonnay, Riesling, Sauvignon Blanc and Semillon. Only a small proportion of the genes within the berry skin showed a three-fold or greater difference in expression level after ripening commenced. Most of the differences appear to arise from environmental signals rather than genome differences

Wendell Berry, Kentucky\u27s Author
No full textMy poster highlights the life and works of Kentucky native Wendell Berry. Mr. Berry is most noted for his writings which encourage the support of local agriculture. I have done a phone interview with Mr. Berry, quotations from which were incorporated into the poster. Mr. Berry has intertwined his philosophy into both his fictional and non- fictional works, and highlights from these works are presented
