Protein Synthesis During Fungal Spore Germination Ii. Aminoacyl-Soluble Ribonucleic Acid Synthetase Activities During Germination Of Botryodiplodia Theobromae Spores, James L. Van Etten, Robert Brambl

Department of Plant Pathology: Faculty Publications

The specific activities of 13 aminoacyl-soluble ribonucleic acid (sRNA) synthetases were measured at various time intervals during the germination of Botryodiplodia theobromae conidiospores. The enzyme activities were low or absent in ungerminated spores, and they increased rapidly as germination proceeded. When extracts of the ungerminated spores were prepared with mortar and pestle, very little or no enzyme activity was detected. When the extracts were prepared with a mechanical homogenizer, however, they exhibited some enzyme activity, although less than did the extracts from germinated spores. Enzyme activities from germinated spores were approximately the same, regardless of the method of preparation. The …

The Certified Strains Of Subterranean Clover : Their Origin, Potential Use And Identification, B J. Quinlivan, C. M. Francis, M. L. Poole

Journal of the Department of Agriculture, Western Australia, Series 4

SUBTERRANEAN CLOVER originated in the countries surrounding the Mediterranean Sea and in parts of Western Europe.

Therefore it is not surprising that it grows well in the agricultural districts of Western Australia, for these regions have a typically Mediterranean climate with cool wet winters and hot dry summers.

Cyanogenetic Plants Of Western Australia, T E H Aplin

Journal of the Department of Agriculture, Western Australia, Series 4

THIS article deals with the more important cyanogenetic plants found in Western Australia.

It also deals with plants which have not been proved as cyanogenetic but which do produce toxic effects similar to those produced by cyanogenetic plants.

Symptoms, post mortem appearances and the treatment for affected stock are also dealt with.

Pressurised Soil Fumigation Equipment For Control Of Eelworm, C W. Robartson

Journal of the Department of Agriculture, Western Australia, Series 4

THE treatment of soil infested with eelworms involves the use of chemical fumigants usually in the form of volatile liquids.

This article gives details for the construction of a simple pressurised fumigator which could be easily made by most orchardists, vignerons and market gardeners.

Maintenance Phosphorus And Sulphur For Pastures : Progress Report, Walter Jacob Cox

Journal of the Department of Agriculture, Western Australia, Series 4

PASTURE IMPROVEMENT has been based on topdressing with superphosphate, which supplies sulphur as well as phosphorus.

In the past, all the benefit due to superphosphate was attributed to the phosphorus.

It is only in recent years that the importance of the sulphur has been appreciated.

Why Australia Needs Plant Quarantine, A T. Gulvin

Journal of the Department of Agriculture, Western Australia, Series 4

LATE blight of potatoes in 1830, powdery mildew of grapes in 1847, phylloxera in 1861, downy mildew in 1875, and black rot in 1838 . . . It was this grim list of plant disease epidemics in Europe that forced Governments to protect plants by quarantine.

Cereal Eelworm : A New Disease Of Cereal Crops In The Geraldton Area, R J. Parkin, Olga M. Goss

Journal of the Department of Agriculture, Western Australia, Series 4

CEREAL eelworm (Heterodera avenae) is a potentially serious disease of crops which was seen in the Geraldton area for the first time in the 1966-67 season.

It was first identified in this State at Beverley in 1958 and later near Northam in 1963.

The Geraldton region has been the only area found to be affected since.

The disease was identified on eight properties in 1966-67, and a further ten properties in 1967- 68. There are indications that many more properties could be affected in varying degrees.
