TL;DR: A comparison of the globulins, vicilin and legumin, prepared by isoelectric precipitation, of the seeds of three species of the Vicieae, namely Pisum sativum, Vicia faba and Cicer arietinum, was made in this paper.
Abstract: Summary
A comparison has been made of the globulins, vicilin and legumin, prepared by isoelectric precipitation, of the seeds of three species of the Vicieae, namely Pisum sativum, Vicia faba and Cicer arietinum. Their amino acid composition, band patterns after electrophoresis upon polacrylamide-urea gels, fingerprint patterns of their tryptic digests and N-terminal amino acids were compared. Considerable portions of the amino acid sequences of vicilin and legumin of Pisum sativum are probably the same or very similar and both proteins consist of a number of sub-units. Vicia faba and Cicer arietinum also contain two proteins homologous with the vicilin and legumin of Pisum sativum. The homologous proteins of the three species resemble each other more closely than do the vicilin and legumin of any one species.

TL;DR: Evidence is found that cucumber plants treated with auxins or CEPA also produce ethylene, which, it is suggested, alters the sex expression of the treated plants.
Abstract: Laibach and Kribben1 and others2,3 have reported altering the sex expression of monoecious cucumber plants by applying auxins to growing plants. The treatments increased the ratio of female to male flowers. A considerable change toward femaleness in cucumbers was reported4 as a result of a single treatment with 2-chloroethylphosphonic acid (CEPA), which causes the release of ethylene5. There are reports that the production of ethylene is induced in many plants after treatment with indoleacetic acid (IAA)6,7 or naphthaleneacetic acid (NAA)8. We have evidence that cucumber plants treated with auxins or CEPA also produce ethylene, which, we suggest, alters the sex expression of the treated plants.

TL;DR: A modified version of the potometer designed by Gregory and Woodford (1939) was used to supply separate zones, and the amounts of nitrogen absorbed were determined with the stable isotope lON as mentioned in this paper.
Abstract: Measurements were made of the uptake of ammonium and nitrate by successive zones of the radicle of intact seedlings of Pisum sativum L. A modified version of the potometer designed by Gregory and Woodford (1939) was used to supply separate zones, and the amounts of nitrogen absorbed were determined with the stable isotope lON.

TL;DR: Results indicate that high enzyme activity is associated with cells of the root cap, outer layers of the cortex, differentiating xylem elements and phloem fibres, and cortical cells surrounding emerging lateral roots in Pisum sativum.

TL;DR: The volatile fractions extracted from unblanched changes in the volatile fraction during extraction were of similar qualitative but which provide maximum practical protection against markedly different quantitative composition.
Abstract: The volatile fractions extracted from unblanched changes in the volatile fraction during extraction. green peas by three distillation techniques and by Vacuum sublimation, conducted under conditions vacuum sublimation were of similar qualitative but which provide maximum practical protection against markedly different quantitative composition. With enzymic, microbial, and thermal changes, is recomblanched peas the extracts provided by all the mended as a reference method for assessing the methods examined were identical.

TL;DR: The oestrogenic activity of Glycyrrhiza glabra extract, Pimpinella anisum oil, Pomegranate seed oil, Trifolium alexandrinum and Palm kernel extracts has been studied on mouse and rat vagina and on uterine development of mice or rabbits.
Abstract: The oestrogenic activity ofGlycyrrhiza glabra extract,Pimpinella anisum oil, Pomegranate seed oil,Trifolium alexandrinum and Palm kernel extracts has been studied on mouse and rat vagina and on uterine development of mice or rabbits. The activity has also been compared with that of the natural oestrogen, oestradiol. Moreover, the relationship between the natural hormones and phytoestrogens in these vegetable food stuffs has also been demonstrated. The doses of these substances producing this effect which corresponded to that of 0.1 µg of oestradiol were: 50 mg, 0.2 ml, 0.4 ml, 200 mg and 200 mg respectively. The oxytoxic effect of various foods has also been tested on the motility of the uterus at various stages of the sex cycle.Portulaca, cucumber and clover intensified the movements of the pregnant uterus to a great extent, Clover, on the other hand, though stimulating the pregnant uterus, inhibited the oestrous and monoestrous uterus.Corchorus olitorius seeds,Lupinus termis seeds,Pisum sativum, Allium cepa, Petroselinum, Zea mays, Cicer arietinum, Allium sativum, Cyperus and Fenugreek increased the motor activity of the uterus at oestrus, nonoestrus and pregnancy. Moreover,Corchorus increased the uterine response to pitocin as it intensified its effect on the uterine movements, in vitro.

TL;DR: The terminal buds of intact dark grown Alaska pea plants respond to low intensity red light by an enhanced rate of expansion of their leaflets by increasing the ribosomal fraction of the RNA content of the terminal buds.
Abstract: The terminal buds of intact dark grown Alaska pea plants (Pisum sativum) respond to low intensity red light by an enhanced rate of expansion of their leaflets. Twenty four hours after irradiation, red light was found to have increased the ribosomal fraction of the RNA content of the terminal buds. The increase in total RNA liter did not occur if the red light was immediately followed by irradiance with low intensity far red light.
TL;DR: Although germination of spores of both species occurred in the absence of an exogenous energy source, it was enhanced by various mono- and di-saccharides as well as by various plant extracts such as orange juice.
Abstract: Spores of Helminthosporium sativum germinated well at temperatures 30–39 °C while spores of H. pedicellatum germinated best at 39 °C with a lower percentage germination at lower or higher temperatures. Although germination of spores of both species occurred in the absence of an exogenous energy source, it was enhanced by various mono- and di-saccharides as well as by various plant extracts such as orange juice. The viability of these spores remained high (above 80%) for over 2 years when stored with a moisture content of 11% at 4 °C. The constituents of spores of both fungi were quite similar with lipids composing about 10% of the dry weight and carbohydrates 5.5–8.3%. Trehalose and mannitol were the most abundant carbohydrates. Spores of H. sativum had an endogenous respiration rate that was about 2–3 times greater than that of H. pedicellatum spores. The respiration rate of spores of both fungi could be stimulated by various energy sources, including sugars and some polyols. The greatest stimulator of r...

TL;DR: According to the host range, symptoms on pea plants and physical properties the virus isolate studied resembles some isolates described in the U.S. and represents a PEMV strain different from those reported so far in Czechoslovakia.
Abstract: Pea enation mosaic virus (PEMV) was isolated from disea sed field pea (Pisum sativum L.ssp. arvense A.Gr.) and broad bean (Faba vulgaris Moench) plants grown as filed crops at Bohumilice in Bohemia. The virus proved to be pathogenic for the following plant species:Pisum sativum L. cv. Raman,Faba vulgaris Moench,Lens culinaris Med.,Vicia sativa L.,Lathyrus odoratus L.,Glycine soja L.,Phaseolus vulgaris L.,Chenopodium amaranticolorCoste andReyn,Nicotiana clevelandiGray,Trifolium incarnatum L. The dilution end point of the isolate was higher in pea plants (10−4) than in broad bean plants (10−2). The thermal inactivation point was 65–68° and the longevityin vitro between 10 and 14 days. According to the host range, symptoms on pea plants and physical properties the virus isolate studied resembles some isolates described in the U.S.A. and represents a PEMV strain different from those reported so far in Czechoslovakia.
