A Re-Examination of the Relative Turgidity Technique for Estimating Water Deficits in Leaves
Tập 15 Số 3 - Trang 413 - 1962
The relative turgidity technique consists in comparing the initial and turgid
water contents, on a percentage basis, of disks punched from leaves, the turgid
water content being obtained by floating the disks on water.
Storage of Two-Cell Mouse Embryos in Vitro
Tập 22 Số 4 - Trang 1065 - 1969
There are reports of the storage at O-lOoC of fertilized rabbit (Chang 1947,
1948; Hafez 1965) and sheep ova (Averill 1956; Kardymowicz et al. 1963;
Kardy-mowicz, Kardymowicz, and Grochowalski 1966; Kardymowicz, Kardymowicz, and
Kremer 1966). However, the storage of fertilized mouse ova in vitro does not
appear to have been studied. Wales (1969) found that glycolysis at 37�C by
cultured blastocyst...
Studies on The Greening of Dark-Grown Bean Plants II. Development of Photochemical Activity
Tập 17 Số 1 - Trang 93 - 1964
A study of the photochemical activity of plastids isolated from etiolated bean
leaves which had been illuminated for increasing periods was undertaken.
Proplastids isolated from etiolated leaves were inactive in the Hill reaction.
Photochemical ferricyanide reduction was obtained with plastids isolated from
etiolated leaves which had been illuminated for 6 hr. The reduction increased to
a maximum ...
Liver Pathology in Mice in Poisoning by the Blue-Green Alga Microcystis Aeruginosa
Tập 34 Số 2 - Trang 179 - 1981
The bloom-forming M. acruginosa contains a peptide hepatotoxin. Injection of
algal extracts or of solutions of purified toxin (5 x LDlOo approx.) into mice
was shown to cause an increase in liver weight of 63 � 11 % within 45 min due to
an increase in blood content of the organ. At the same time aspartate amino
transferase and lactate dehydrogenase increased 50-fold and 20-fold respectively
in ser...
The Early Stages of Grain Development in Wheat: Response to Light and Temperature in a Single Variety
Tập 23 Số 4 - Trang 765 - 1970
For wheat plants (cv. Gabo) grown under natural daylight at a temperature of
21/16�C, increase in dry weight of the stem exceeded that of the ear for the
first 10 days following anthesis. Higher temperatures (27/22�C) resulted in a
greater rate of grain development, with a corresponding increase in the rate of
cell division in the endosperm tissue, and a shortening of the stem growth
period. Despi...
Simulation of Genetic Systems by Automatic Digital Computers II. Effects of Linkage on Rates of Advance Under Selection
Tập 10 Số 4 - Trang 492 - 1957
Rates of progress of single populations under selection pressure have been
simulated by an automatic electronic computer. Varying intensities of selection
and tightness of linkage are compared, showing that linkage produces no
qualitative effect on the rates of advance at values greater than 0�005, i.e.
0�5 per cent. recombination.
The Evolutionary Significance of Sugar Accumulation in Saccharum
Tập 16 Số 4 - Trang 737 - 1963
Sugar levels in the various species of the Saccharum complex suggest an
evolutionary increase in sugar content. Under suitable ecological conditions,
survival through sucker growth may be dependent on rapid mobilization of stored
carbohydrate. Selection pressure for sucrose storage would then oocur if sucrose
was more readily remobilized than other storage carbohydrates. It is suggested
that this ...
Oestrogen Sulfotransferase: Molecular Cloning and Sequencing of cDNA for the Bovine Placental Enzyme
Tập 41 Số 4 - Trang 507 - 1988
The female sex hormone, oestrogen, plays a central role in breast cell
proliferation in both the normal and malignant state. It controls transcription
from several genes, including that for the progesterone receptor, and in
endometrial tissue, via this receptor, it controls the gene for the enzyme
oestrogen sulfotransferase. This enzyme may control the level of the oestrogen
receptor by sulfurylat...
Isozyme Studies on the Origin and Evolution of Puccinia Graminis F. SP. Tritici in Australia
Tập 35 Số 2 - Trang 231 - 1982
Isozyme phenotypes for eight enzyme systems were used to assess the origins and
evolution of P. graminis f. sp. tritici (the wheat stem rust pathogen) in
Australia. The results obtained by this approach agreed with pathways postulated
on the basis of virulence studies, confirming the suggestion that most of the
major changes in the wheat stem rust pathogen flora of Australia have resulted
from ove...
Studies on Phytoalexins VII. Chemical Stimulation of Pisatin Formation in Pisum Sativum L.
Tập 18 Số 4 - Trang 803 - 1965
Chemical reagents were tested for their effectiveness to stimulate pisatin
production in the endocarp of pea pods. The following compounds were found most
active:
