Pea Seed

Due to low culturing costs and high seed protein contents, legumes represent the main global source of food protein. Pea (Pisum sativum L.) is one of the major legume crops, impacting both animal feed and human nutrition. Therefore, the quality of pea seeds needs to be ensured in the context of sustainable crop production and nutritional efficiency. Apparently, changes in seed protein patterns might directly affect both of these aspects. Thus, here, we address the pea seed proteome in detail and provide, to the best of our knowledge, the most comprehensive annotation of the functions and intracellular localization of pea seed proteins. To address possible intercultivar differences, we compared seed proteomes of yellow- and green-seeded pea cultivars in a comprehensive case study. The analysis revealed totally 1938 and 1989 nonredundant proteins, respectively. Only 35 and 44 proteins, respectively, could be additionally identified after protamine sulfate precipitation (PSP), potentially indicating the high efficiency of our experimental workflow. Totally 981 protein groups were assigned to 34 functional classes, which were to a large extent differentially represented in yellow and green seeds. Closer analysis of these differences by processing of the data in KEGG and String databases revealed their possible relation to a higher metabolic status and reduced longevity of green seeds.

Seed Proteome

Legume crops represent the major source of food protein and contribute to human nutrition and animal feeding. An essential improvement of their productivity can be achieved by symbiosis with beneficial soil microorganisms—rhizobia (Rh) and arbuscular mycorrhizal (AM) fungi. The efficiency of these interactions depends on plant genotype. Recently, we have shown that, after simultaneous inoculation with Rh and AM, the productivity gain of pea (Pisum sativum L) line K-8274, characterized by high efficiency of interaction with soil microorganisms (EIBSM), was higher in comparison to a low-EIBSM line K-3358. However, the molecular mechanisms behind this effect are still uncharacterized. Therefore, here, we address the alterations in pea seed proteome, underlying the symbiosis-related productivity gain, and identify 111 differentially expressed proteins in the two lines. The high-EIBSM line K-8274 responded to inoculation by prolongation of seed maturation, manifested by up-regulation of proteins involved in cellular respiration, protein biosynthesis, and down-regulation of late-embryogenesis abundant (LEA) proteins. In contrast, the low-EIBSM line K-3358 demonstrated lower levels of the proteins, related to cell metabolism. Thus, we propose that the EIBSM trait is linked to prolongation of seed filling that needs to be taken into account in pulse crop breeding programs. The raw data have been deposited to the ProteomeXchange with identifier PXD013479.

Representative Samples

The goal of the trial was to reduce the content of antinutritional substances in pea (Pisum sativum L.) seeds in order to enhance its use in livestock nutrition. A variety of field pea (Pisum sativum L.) with a high content of antinutritional substances and favourable production traits (Gotik) was chosen. Native and heat-treated pea seeds were used to collect representative samples (n = 6) for analytical purposes. The technology (V-0 technology, Czech patent No. 285745) was further modified by adjusting the reactor temperature, the duration of exposure to that temperature, and the duration of ageing of the material treated in this way (V-I and V-II technologies). The methodology of treatment is based on exposing pea seeds to vapour, organic acids and selected oxides.The monitored parameters included antinutritional substances. As far as the antinutritional substances were concerned, the content of trypsin inhibitors in native pea seeds (P) was around 15.4 ± 0.5 TIU. After treatment with technologies V-0, V-I, and V-II its activity dropped by 83.8, 80.5 and 83.8%, respectively. The pre-treatment titre of lectins (P) was 717 ± 376. It dropped by 70.3, 35.7 and 73.2% after treatment with technologies V-0, V-I and V-II, respectively. The content of tannins measured by the amount of gallic acid in native pea seeds was 49.1 ± 2.7 mg per kg. It dropped by 41.4, 32.0 and 46.2% after the application of the above-mentioned technologies. The content of indigestible oligosaccharides causing flatulence was less affected by the treatments. The pre-treatment content of raffinose was 9.5 ± 0.5 g/kg. The drop associated with the treatment was 9.5, 6.3 and 10.5%, respectively. The pre-treatment content of stachyose was 21.4 ± 0.8 g/kg and after treatment with technologies V-0 and V-II it dropped by 7.0% and by 16.4%, respectively. The application of technology V-I did not result in a drop in the content of stachyose. The content of verbascose in native pea seeds was 16.1 g/kgand the treatment with technologies V-0; V-I and V-II resulted in a drop by 7.5, 5.6 and 20.5%, respectively. As for the detected phenolic acids, with the exception of caffeic acid, not a drop, but an increase in their content was recorded. Isoflavone oestrogens such as daidzein and genistein also recorded a small increase in their content. The results of the trial lead us to conclude that the above-described methods of pea seed treatment, especially the V-II variant, proved to be useful and can be recommended for practical use.

Pea seed-borne mosaic virus (PSbMV) was first identified in Canadian field pea (Pisum sativum L.) breeding lines in 1974. Since then, an extensive program has been underway to eradicate this virus from the breeding lines. At the Morden Research Station, nearly 2000 breeding lines were evaluated. The virus was assayed by infectivity tests using the local lesion host Chenopodium amaranticolor, and by a gel immunodiffusion test. PSbMV was detected in 1361 lines. The level of infection within lines varied from 1 to 3%. Due to the restricted extent of the virus in the breeding lines, it was possible to continue the breeding program without a serious loss in germplasm.

<p>La valoración del efecto del ambiente en el desarrollo de los cultivos es importante para la determinación de zonas aptas y la planificación de la producción. En esta investigación se realizaron cuatro ensayos para evaluar el desarrollo de las plantas de arveja (<em>Pisum sativum </em>L.) variedad Santa Isabel en condiciones de la sabana de Bogotá, Colombia, (2640 msnm, 14°C, 80% H.R., 800 mm de lluvia anual), tema sobre el cual no hay información. Se realizaron dos ensayos bajo cubierta plástica (21°C ± 2,5°C, promedio ± DE) y dos a campo abierto (13,9°C ± 1,2°C). Se evaluó el tiempo de la siembra a la emergencia, la tasa de aparición de nudos en el tallo principal, el inicio de la floración, la duración del ciclo de la siembra hasta la cosecha, el número de nudos totales en la cosecha y el número de nudos con flor. Se encontró que la temperatura bajo cubierta plástica aceleró en 10 días la emergencia de las plantas y redujo el filocrón de 3,05 a 2,72 días/nudo, lo cual a su vez adelantó el momento de floración y cosecha entre 15 y 20 días. La tasa de aparición de nudos no varió significativamente por el cambio de la fase vegetativa a reproductiva. Los resultados contribuyeron a respaldar el modelo dentado de desarrollo vegetal en función de la temperatura para arveja, según el cual el crecimiento es máximo en un rango de temperatura óptima, que se sugiere está entre los 14°C y 21°C. </p><p> </p><p><strong>Phenology of pea crop (</strong><strong><em>Pisum sativum </em></strong><strong>L. var. Santa Isabel) in the Bogotá plateau at open field and under plastic cover</strong> </p><p>The assessment of environment effects on plant development is important to identify suitable zones and schedule crop production. In this research, plant development of pea (<em>Pisum sativum </em>L. var. Santa Isabel) was evaluated under Bogotá flat highland, Colombia, environmental conditions (2640 m over sea level, 14°C, 80% R.H., rainfall of 800 mm/year). Two experiments were done under plastic cover (21°C ± 2,5°C, mean ± SD), and two at open field (13,9 ± 1,2°C). Following variables were evaluated: time to emergence, cycle duration from sowing to harvest, total nude number at harvest and flowering nude number at harvest. It was shown that temperature under plastic cover accelerate plant emergency in 10 days and reduce phyllochron from 3,05 to 2,72 day/node, so the flowering time was accelerated between 15 and 20 days. Node rate appearance did not change from the vegetative to reproductive stage. The results confirm the dent-like model of pea plant growth responses to temperature regimes, so the crop growth had a maximum at a plateau in a temperature range which could be between 14°C and 21°C. </p>

Pea Seed

The seedcoats contain almost all of the acid phosphatase activity (EC 3.1.3.2) in the pea seed in the earliest stages of expansion. The seedcoat activity is maximal by the end of the period of rapid cell expansion and declines as the embryo matures. The developing cotyledons show a later rise in acid phosphatase activity to a maximum shortly before dehydration. The activity in the embryonic axis shows a marked increase only during dehydration. The acid phosphatase activity in the seedcoats results almost entirely from an isoenzyme with high electrophoretic mobility in 5.5% polyacrylamide gels (RF 0.97). This isoenzyme has not been detected in other tissues from the plant. The phosphatase activity in the cotyledons is accounted for by one major isoenzyme at RF 0.75 and by four minor components. The partially purified enzyme from the seedcoats shows a broad pH optimum from pH 5.0 to pH 6.0. In contrast, the preparation from the cotyledons has an optimum close to pH 5.6 and is slightly more sensitive to inhibition by 0.2 mM PI.
