TL;DR: The protein-synthesizing capacity of 3-day-old seedlings of radish and lettuce grown in the presence of earthworm casts was investigated using L-14-C-leucine incorporation, finding no significant differences in protein content.
Abstract: The protein-synthesizing capacity of 3-day-old seedlings of radish and lettuce grown in the presence of earthworm casts was investigated using L-14-C-leucine incorporation. The results showed that earthworm casts increased protein synthesis by 24% for lettuce and 32% for radish, althought no significant differences in protein content were evident.

TL;DR: These phenolic acids profoundly affected root morphology in terms of extension growth of the main root and the number and size of the lateral roots and the precise growth effects depended on the phenolic acid.
Abstract: At relatively high concentrations (1 mM), ferulic, vanillic, p-coumaric, p-hydroxybenzoic, syringic and caffeic acids inhibited the growth of roots of Pisum sativum L cultured in a Hoagland nutrient solution under axenic conditions. These phenolic acids also profoundly affected root morphology in terms of extension growth of the main root and the number and size of the lateral roots. The precise growth effects depended on the phenolic acid. At concentrations that inhibited an increase in the length of the main root, the phenolic acids also inhibited cell division. To produce the maximum growth effect, the phenolic acids must be present continuously. Lower concentrations (1 μM)of the phenolic acids also affected root growth and morphology when the nitrogen content of the nutrient solution was limiting.

TL;DR: Treatment of Pisum sativum (L.) cv ;Sparkle' with ethylmethane sulfonic acid produced a stable mutant, E107, which forms few nodules, and the mutant allele exhibits other pleiotropic properties including bronze necrotic spots on the leaflets and high accumulation of iron in the shoot.
Abstract: Treatment of Pisum sativum (L.) cv `Sparkle9 with ethylmethane sulfonic acid produced a stable mutant, E107, which forms few nodules. The mutant allele exhibits other pleiotropic properties including bronze necrotic spots on the leaflets and high accumulation of iron in the shoot. The mutant phenotype is under monogenic recessive control. The gene, designated brz (bronze), is nonallelic with two other genes conditioning necrotic spots on leaves of other mutants of P. sativum. The brz allele was located on chromosome 4 by linkage with wax production controlled by alleles at the was locus.

TL;DR: Antibodies raised against two pea (Pisum sativum L. cv. Birte) seed lipoxygenases have been used to analyze Lipoxygenase heterogeneity in seeds and in other organs and at least seven different polypeptides were identified in vivo.
Abstract: Antibodies raised against two pea (Pisum sativum L. cv. Birte) seed lipoxygenases have been used to analyze lipoxygenase heterogeneity in seeds and in other organs. At least seven different polypeptides were identified in vivo; five of these were identified as precursors synthesized in vitro. The developmental appearance of the seed polypeptides has been analyzed and 'early' and 'late' forms were identified. Limited N-terminal sequence data indicated further heterogeneity when compared with sequences predicted from cDNAs.

TL;DR: Analysis of interphase nuclei at different thresholds of optical density showed that certain chromatin fractions are involved in the variations of nuclear DNA content of early prophases after ethanol-acetic acid fixation.
Abstract: The cultivars or experimental lines ofPisum sativum were analyzed cytophotometrically for nuclear DNA content of early prophases after ethanol-acetic acid fixation. Wide variability was found (from 3.93 to 5.07pg per haploid nucleus). This result was confirmed by the cytophotometric analysis of interphase nuclei isolated from leaf tissues fixed in formalin. Analysis of interphase nuclei at different thresholds of optical density showed that certain chromatin fractions are involved in the variations.
TL;DR: The Flea Beetle Phyllotreta striolata (F) was attracted to the cruciferous plants Brassica oleracea L. and Raphanus sativus L., but not to B. campestris L. as mentioned in this paper.
Abstract: The flea beetle, Phyllotreta striolata (F.), was attracted to the cruciferous plants Brassica oleracea L. and Raphanus sativus L., but not to B. campestris L. and B. napus L. which are important natural host plants, nor to Pisum sativum (L.), a legume. The presence or absence of attraction was demonstrated by exposing small groups of caged plants to natural populations and trapping beetles near the plants. In choice and no-choice laboratory feeding experiments, P. striolata fed on eight Cruciferae in the genera Brassica, Raphanus, and Sinapis but not on P. sativum. Phyllotreta striolata fed less on S. arvensis L. and S. alba L. than on plants in the other genera. Within Brassica, B. oleracea, B. napus, and B. campestris were preferred over B. juncea (L.) Czern and B. nigra (L.) Koch. Discrimination at the attraction phase of host selection did not account for discrimination shown in laboratory feeding experiments nor in the natural attack of flea beetles on cruciferous crops.
TL;DR: Three isoforms of alpha-glucosidase have been extracted from pea seedlings and separated by DEAE-cellulose and CM-Sepharose chromatography, and two were most active under acid conditions, and appeared to be apoplastic and a neutral form was identified as a chloroplastic enzyme.
Abstract: Three isoforms of alpha-glucosidase (EC 3.2.1.20) have been extracted from pea (Pisum sativum L.) seedlings and separated by DEAE-cellulose and CM-Sepharose chromatography. Two alpha-glucosidase isoforms (alphaG1 and alphaG2) were most active under acid conditions, and appeared to be apoplastic. A neutral form (alphaG3) was most active near pH 7, and was identified as a chloroplastic enzyme. Together, the activity of alphaG1 and alphaG2 in apoplastic preparations accounted for 21% of the total acid alpha-glucosidase activity recovered from pea stems. The vast majority (86%) of the apoplastic acid alpha-glucosidase activity was due to alphaG1. The apparent K(m) values for maltose of alphaG1 and alphaG2 were 0.3 and 1.3 millimolar, respectively. The apparent K(m) for maltose of alphaG3 was 33 millimolar. The respective native molecular weights of alphaG1, alphaG2, and alphaG3 were 125,000, 150,000, and 110,000.

TL;DR: The results of this preliminary study suggest that the generally accepted view that humic substances exert a positive effect on plant growth may not occur when humic substance interact with herbicides.
Abstract: Slight increases in root length and dry matter production were measured in roots and shoots of Pisum sativum seedlings, when germinated seeds were grown for eight days in a controlled environment chamber, on Nitch nutrient solution to which 10 mg L-1 soil humic acid (HA) had been added. A concentration of 100 mg L-1 of HA produced a small reduction in dry matter production of shoots. In the presence of herbicides, 10 mg L-1 cycluron or 100 mg L-1 prometone, root elongation and shoot growth was reduced by varying degrees with respect to the control. Nutrient solutions containing 100 mg L-1 cycluron, 10 or 100 mg L-1 alachlor, or as little as 0.1 mg L-1 of 2,4-D resulted in an almost complete suppression of the growth of pea seedlings. The addition of 10 or 100 mg L-1 of HA to nutrient solution containing the herbicide was found to be either ineffective in enhancing growth, or even further reduced growth, compared to samples grown in the presence of the herbicide alone. The results of this preliminary study suggest that the generally accepted view that humic substances exert a positive effect on plant growth may not occur when humic substances interact with herbicides.

TL;DR: The protein content of legumes is affected by genetic as well as environmental factors, while the nutritional quality depends on several factors such as their digestibility, balance of essential amino acids, and the presence of certain toxic substances.
Abstract: Legumes and oilseed crops are the most important source of plant proteins and energy, and are cultivated throughout the world in wide areas (Table 1). The grain legumes are grown in the tropics, subtropics and temperate zones. They are amongst the earliest food crops to be cultivated by man, and constitute one of the most importent sources of dietary protein, especially in Asia, Latin America and Africa. Some species which are commonly cultivated for human consumption are peanut (Arachis hypogaea), pigeon pea (Cajanus cajan), chickpea (Cicer arietinum), soybean (Glycine max), lathyrus pea (Lathyrus sativus), lentil (Lens esculenta), lima bean (Phaseolus lunatus), kidney or navy bean (Phaseolus vulgaris), garden pea (Pisum sativum), winged bean (Psophocarpus tetragonolobus), broad bean (Vicia faba), blackgram (Vigna mungo), greengram (Vigna radiata), cowpea (Vigna unguiculata), etc. They are of paramount importance not only for their value as human food, but also because of the high protein content for livestock and fish feed. Moreover, legumes are endowed with the ability to fix atmospheric nitrogen and thus improve soil fertility. In different countries they are consumed in various forms, such as immature seed, dry grain, as condiments or roasted grain, for flour production, and as fermented products (Parpia 1973). The protein content of legumes is affected by genetic as well as environmental factors, while the nutritional quality depends on several factors such as their digestibility, balance of essential amino acids, and the presence of certain toxic substances.
TL;DR: Two lines were investigated and resulted to be different from the standard P. sativum karyotype and from each other and both lines showed pericentric inversions in chromosome VI that involved different segments.
Abstract: SUMMARYP. sativum ect. abyssinicum was studied by karyotype and meiotic analyses. Two lines were investigated and resulted to be different from the standard P. sativum karyotype and from each other. Line 2 showed a reciprocal interchange involving chromosomes III and IV and both lines showed pericentric inversions in chromosome VI that involved different segments.
TL;DR: N6- Methylagmatine was found to be present in seeds and seedlings of Glycine max, Psophocarpus tetragonolobus, Pisum sativum, Medicago sativa, Phaseolus vulgaris, Lathyrus odoratus and Arachis hypogaea among 20 species of leguminous plants tested.
TL;DR: The activity of cellulase and pectin methyl esterase and the protein and chlorophyll contents in potted plants showed a gradual increase from the control up to 2.5% concentration of vinasse, but decreased at higher concentrations, which may be due to the high BOD load and the presence of cell wall cations in it.

TL;DR: At equivalent level of stress, NaCl proved more harmful to germination, seedling growth, vigour index, as well as initial mobilizing efficiency of food material from seed to the growing seedling, while PEG-6000 was more harmful than NaCl to imbibition rate and mobilization efficiency in further days.
Abstract: Germination and seedling growth of pea (Pisum sativum L. cv. Rachna) was studied in salts and PEG-6000 solution having osmotic potentials −0.1, −0.2, −0.3, −0.4 and −0.5 MPa. At equivalent level of stress, NaCl proved more harmful to germination, seedling growth, vigour index, as well as initial mobilizing efficiency of food material from seed to the growing seedling, while PEG-6000 was more harmful to imbibition rate and mobilization efficiency in further days.
TL;DR: The detailed distribution of 14C in the roots of Pisum sativum showed that 44% of the absorbed 14C had been metabolized to compounds other than valine but only 4% appeared as [14C]leucine, suggesting that a range of plants have a significant ability to respire valine.
TL;DR: There were qualitative similarities which correlated with the presence of chlorophyll in all the tissues, and the Red/Far-Red ratio decreased as light penetrated the pod and testa, so that the photomorphogenic environment of the embryo had a much lower R/FR ratio than that of daylight.
TL;DR: Green field pea (Pisum sativum L.) genotypes were grown in the field and harvested before and after exposure to moist conditions, and percentage of hard seed was strongly correlated with percentage of bleached seeds and color at last harvest, and would provide the basis of a screening technique.
Abstract: Green field pea (Pisum sativum L.) genotypes were grown in the field and harvested before and after exposure to moist conditions. The seeds were evaluated for percent bleaching and intensity of green color. Samples from the first harvest were placed on moist paper in petri dishes for later recording of percent hard seeds and color. Percentage of bleached seeds and color at last harvest gave a good evaluation of resistance to color loss of the genotypes. Percentage of hard seed was strongly correlated with percentage of bleached seeds (negative) and color at last harvest (positive), and would provide the basis of a screening technique. However, non-soaking on moist paper may be associated with cooking quality, in which case the method would be of value in selecting lines for the split green pea market, but not for the whole green pea market.Key words: Pea (green field), Pisum sativum L., cotyledon color, seed bleaching
