    Notes: The quality of two new drought-resistant varieties of rice (IR441 and IR3304) grown in Egypt, were compared with three commercial varieties (Selection 180, Reiho and Giza 172). Based on milling yield, IR441 and IR3304 showed lowest rice quality. Gelatinization temperature was highest in IR441 and lowest in IR3304 and Giza 172. During cooking, water uptake ratio and elongation ratio were higher in IR441 and Selection 180. Protein content was in the range 4–6% for all varieties. Amino acid analysis indicated nutritional superiority of Selection 180 over the other varieties. With the exception of lysine and threonine, the amount of each of the other essential acids in IR441 and Reiho matched or exceeded the FAO/ WHO pattern. IR3304 is deficient in the most number of essential acids (lysine, threonine, and isoleucine).

    Over-expression of the cercosporin facilitator protein, CFP, in Cercospora kikuchii up-regulates production and secretion of cercosporin (2001)

    Notes: CFP (cercosporin facilitator protein), a light-regulated gene from the soybean fungal pathogen Cercospora kikuchii, encodes the putative major facilitator transporter of the fungal polyketide cercosporin. Gene disruption of CFP in C. kikuchii strain Gus-3 resulted in dramatically reduced cercosporin production and virulence, and increased sensitivity to the toxin. Two C. kikuchii transformant strains (10-1 and 10-11) that over-produce cercosporin were recovered from the complementation of CFP gene-disrupted strain Gus-3. Southern analysis revealed that these strains contained multiple genomic copies of CFP and over-expressed CFP transcript and protein. Although 10-1 and 10-11 produce and secrete significantly elevated levels of cercosporin, they exhibit wild-type resistance to cercosporin, and maintain a wild-type pattern of light-regulated toxin accumulation. Restoration of wild-type cercosporin resistance in 10-1 and 10-11 suggests that CFP does contribute substantially to cercosporin resistance via toxin secretion. The three-fold increase in toxin accumulation, predominately associated with the mycelium fraction of these CFP multi-copy strains, suggests that CFP may also have a significant, but unknown, role in regulating toxin production.

    Genetically engineered resistance to potato virus X in four commercial potato cultivars (1995)

    Notes: Abstract The genes for the capsid protein (CP) and the 8K movement protein of PVX were introduced into potato (Solanum tuberosum L.) and expressed under the control of CaMV 35S promoter using a binary vector andAgrobacterium tumefaciens. Four commercial potato cultivars (Russet Burbank, Shepody, Desirée and Bintje) have been efficiently transformed. Eleven independent transgenic clones, with CP expression levels higher than 0.05% of the soluble leaf proteins, were analyzed for resistance to inoculation with PVX (5 and 50µg/ml). The resistance of the transgenic plants to PVX was observed with the lower titer of virus inoculation (5 µg/ml) but not with higher titer (50 µg/ml). A significant reduction in the accumulation of virus in the inoculated transgenic potato plants has been observed under greenhouse and field conditions. Furthermore, the CP gene is very stable and is transferred to new plants originated from stem cuttings or from tubers. The transgenic plants appeared to be phenotypically identical to the nontransformed controls.

    Notes: Abstract Osmoregulation and post ischemic glutamate surge suppression (PIGSS) are important mechanisms in the neuroprotective properties of taurine. We studied the role of taurine in PIGSS following transient global forebrain ischemia (TGFI). A group of gerbils received a high dose of continuous intracerebral taurine during the peri-ischemic period. β-alanine was given similarly to a negative control group. The control group consisted of animals undergoing only TGFI. On the fourth day following commencement of drug administration, TGFI was induced. Concurrently, half the animals from each group receiving an agent had intracerebral microdialysis. All animals underwent histological assessment at day 7. The microdialysis and histological data was analyzed. Our results showed that taurine treatment did not cause PIGSS. The histological difference between the three groups was statistically insignificant. We conclude that intracerebral taurine in the dosage administered during peri-ischemic period, does not result in PIGSS or histologically evident neuroprotection.
