Despite the huge efforts and funds expended to try and bring Cacao swollen shoot virus (CSSV) disease under control, the disease has remained largely intractable. Inspired by the need to inject new ideas into the current breeding programmes for CSSV resistance, the interactions between cocoa and the virus in CSSV-infected plants from 3 days post inoculation (dpi) to about 30 dpi were studied us...

Characterization of sugar content and enzyme activity in germinating soybean (Glycine max L. Merrell) seeds led to the discovery of sorbitol accumulating in the axes during germination. The identity of sorbitol was confirmed by relative retention times on high-performance liquid chromatography and gas liquid chromatography and by mass spectra identical with authentic sorbitol. Accumulation of s...

Membrane fractions from seedlings of four soybean [Glycine max (L.) Merr.] lines were examined by radioimmunoassay and hemagglutination assay for the 120,000 dalton soybean lectin. Two of the lines (Sooty and T-102) are genotypically lele and lack buffer-soluble soybean lectin; the remaining two lines (Beeson and Harosoy 63) are Le and produce seeds that contain the lectin (Su et al. 1980 Bioch...

During germination and early growth of castor bean (Ricinus communis), all cellular constituents of the endosperm are eventually transferred to the growing embryo. The present results bear on the transport of breakdown products of nucleic acids. The total content of nucleic acids and nucleotides declines rapidly between day 4 and day 8 of seedling development. Concomitant with this decline, a s...

In the present study, Glycyrrhiza uralensis (Leguminosae) seeds were germinated and grown with different concentrations (0, 0.05, 0.1, 0.2 and 0.4 mmol/l) of cadmium acetate, in order to investigate the effects of cadmium on the growth, uptake, superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), polyphenol oxidase (PPO) and phenylalanine ammonia-lyase (PAL) activities in Glycyrrhiza u...

A short treatment o f excised buckwheat cotyledons with a solution o f kinetin lead to an up to 9-fold stimulation o f anthocyanin biosynthesis, to an about 50 percent increase in the accum ula­ tion o f rutin, and to an about 30 percent increase, on the average, in the accumulation o f C-glycosylflavones in the treated material during its posttreatment incubation in the dark. When the treated ...

BACKGROUND AND AIMS Imbibition of Japanese soybean (Glycine max) cultivars was studied using micro-magnetic resonance imaging (MRI) in order to elucidate the mechanism of soaking injury and the protective role of the seed coat. METHODS Time-lapse images during water uptake were acquired by the single-point imaging (SPI) method at 15-min intervals, for 20 h in the dry seed with seed coat, and ...

The effects of abscisic acid, zeatin, and gibberellic acid on the development of somatic embryos from cultured cells of caraway (Carum carvi L.) were observed.Somatic embryos complete development on a basal medium without exogenous hormones, but some are subject to developmental abnormalities including malformed cotyledons and accessory embryos. Both zeatin and gibberellic acid, especially in c...

We have measured the amount of tRNA in cotton cotyledons that can be charged with each of the 20 amino acids at four developmental stages in cotyledon embryogenesis and germination. We have examined the number and relative levels of isoaccepting tRNA species for 15 amino acids at the same developmental stages by RPC-2 (Freon) chromatography and by the chromatography of RNAse T1 digests of amino...
