Protoplast Division

Mesophyll protoplasts of two genetically distinct genotypes of N. debneyi were cultured with sustained division following a plating efficiency in excess of 50%. Fully fertile mature plants were regenerated from callus cultures derived from protoplasts. Shoots were induced in medium containing 1 mg/l 6-benzylaminopurine and 0.5 mg/I indole acetic acid. The repeatably high efficiency of protoplast culture was used to evaluate the quantitative effects of two drugs, kanamycin and trimethoprim, which effectively inhibited colony formation at concentrations of 100 and 50 �g/ml, respectively. An enhancer of DNA uptake, poly-L-ornithine, had virtually no effect on sustained protoplast division at a concentration of 7.5 �g/ml or less.

Extracts from eleven different plant species such as jute (Corchorus capsularisL.), cheerota (Swertia chiraitaHam.), chatim (Alstonia scholarisL.), mander (Erythrina variegata), bael (Aegle marmelosL.), marigold (Tagetes erecta), onion (Allium cepa), garlic (Allium sativumL.), neem (Azadiracta indica), lime (Citrus aurantifolia), and turmeric (Curcuma longaL.) were tested for antibacterial activity against potato soft rot bacteria,E. carotovorasubsp.carotovora (Ecc)P-138, underin vitroand storage conditions. Previously,EccP-138 was identified as the most aggressive soft rot bacterium in Bangladeshi potatoes. Of the 11 different plant extracts, only extracts from dried jute leaves and cheerota significantly inhibited growth ofEccP-138in vitro. Finally, both plant extracts were tested to control the soft rot disease of potato tuber under storage conditions. In a 22-week storage condition, the treated potatoes were significantly more protected against the soft rot infection than those of untreated samples in terms of infection rate and weight loss. The jute leaf extracts showed more pronounced inhibitory effects onEcc-138 growth both inin vitroand storage experiments.

The problems of feeding a rapidly expanding world population with decreasing arable land resources are placing increasing demands on our genetic resources and the plant breeders who exploit them. Innovative or novel genetic approaches may provide solutions to some of the problems of genetic analysis and the development of additional genetic variability in plants. The present status of techniques such as wide crossing, DNA feeding, tissue, cell and protoplast culture and somatic cell hybridisation is discussed. Plant tissue culture procedures may enable us to expand the gene pools for disease and pest resistance, greater tolerance to environmental stress, increased quality or possibly to develop new plant types. However, the utility of innovative procedures will require a rigorous evaluation of their potential and limitations, and the ability to produce material which can be readily introgressed into established plant breeding systems.

Hypocotyl Segments

Double haploid (DH) genotypes of canola (Brassica napus L.) have a high level of genetic uniformity but have not been previously tested for genetic transformation. Transgenic plants from three of four DH genotypes derived from cv. Westar were obtained by inoculation of either hypocotyl segments or root explants with Agrobacterium tumefaciens. For hypocotyl transformation, A. tumefaciens strain LBA4404 containing a binary plasmid with the neomycin phosphotransferase gene (nptII) and a CaMV 35S-peroxidase gene cassette was co-cultivated with hypocotyl segments taken from the 5–6-day-old seedlings. Transformation frequencies for hypocotyl explants of two DH genotypes were 0.3–3%. Direct evidence for genetic transformation of hypocotyl explants was obtained through molecular hybridisation analysis. Using this protocol, mature transformed plants were obtained within 4–6 months of co-cultivation. A method of root transformation was successfully modified for one DH genotype of canola and transgenic plants were obtained at a frequency of 2%. Using this protocol, a peroxidase gene promoter–GUS fusion construct was introduced into a DH genotype. Tissue specific GUS expression driven by the peroxidase gene promoter in transgenic plants was analysed by GUS staining. Transformation systems for double haploid canola lines will permit the assessment of introduced genes for their effect on agronomic and physiological traits.
