During Isolation of total rilmnucleic acids from white lupin (Lupinus albus) and their subsequent separation by 10% polyacrylamide gel electrophoresis, a fast migrating RNA band is very well separated. The nucleotide sequence analysis of 76 nucleotide long sequence with many modified nucleosides was found to be identical with that of tyrosine specific tRNA of yellow lupin seeds (Lupinus luteus) and wheat germ (Trtiicum aestivum). Also this tRNATyr is identical with plant amber suppressor tRNA. 'I'he presented approach offers a very rapid method of purification of plant tRNA with UAG suppressor activity.

This paper presents the results of a study on the influence of lead (Pb2+) on DNA integrity on plant cells. The study was performed on the root tips of lupin (Lupinus luteus cv. Juno) seedlings treated with two selected concentrations of Pb(NO3)2: 150 and 350 mg l-1, which were found to inhibit root growth by 50% and 70%, respectively [Ruciłska et al. Plant Physiol. Biochem. 37 (1999) 37187-37194]. Roots exposed to those external lead concentrations took up about 50 and 70 mg l-1 Pb2+ g-1 fresh weight (FW) over 48 h of incubation. A dose-dependent increase in the degree of root injury was observed in the presence of both tested concentrations. The genotoxicity of lead in lupin root cells was analysed using a mild alkaline comet assay at pH 12.3, which allows the detection of single strand breaks. The quantity of the DNA fragments migrating away from the nuclear remnant (tail area) increased proportionally to the lead content inside the roots, and was positively correlated with the degree of root injury. At 150 mg l-1 Pb2+, a high frequency distribution of nuclei having large values of tail lengths and moments was observed. By contrast, the number of nuclei with minimum values of these parameters increased at 350 mg l-1 Pb2+. This data suggests that lead at low concentrations induces the formation of short, rapidly migrating DNA fragments, whereas at higher concentrations, lead probably causes other changes to DNA that result in slower DNA migration in the electric field.

This paper presents some partial results of a study on the financial consequences of lupine breeding in Poland, as well as market conditions for seed trade. Analysis also covers the impact of breeding fees on the financial performance of this business. The research procedure was based on a case study of two domestic plant-breeding companies. The study includs the analysis of funding sources used for lupine seed breeding and the potential financial outcomes of this activity. The plant-breeding companies, covered by this study, are owned by the State Treasury and are organized so that the breeding department is part of a larger agricultural undertaking engaged in multiple production activities. Therefore, accounting data of these undertakings was used in order to determine the economic performance of the breeding department. Also, direct interviews were conducted with breeding department employees and top-level managers. A simulation calculation was also performed under the assumption that the breeding department is an independent undertaking which settles its accounts with the holding on a commercial basis. Therefore, the breeding department was assumed to sell intellectual property consisting of seed fraction “E.” The plant-breeding company is also a sort of seed company which sells the marketable seed fraction K. In summary, lupine breeding is concluded to be a highly profitable business, provided that the plant-breeding departments fully settle their accounts internally and that the breeding fees from seed companies are fully collectable. The development and production potential identified in this study suggests these plants could be used to increase national self-sufficiency in vegetable protein.

Zaprezentowano cząstkowe wyniki badań dotyczące oceny możliwych skutków finansowych hodowli łubinów w Polsce, a także rynkowych uwarunkowań obrotu materiałem siewnym tych roślin. Analizie poddano również wpływ opłat hodowlanych na efekty finansowe tej działalności. Badania mają charakter studium przypadku dwóch krajowych firm hodowli roślin i obejmowały analizę źródeł finansowania hodowli materiału siewnego łubinu, a także potencjalnych skutków finansowych tego przedsięwzięcia. Analizowane zakłady to spółki hodowli roślin Skarbu Państwa, które działają w strukturze, gdzie dział hodowli jest częścią większego przedsiębiorstwa rolnego nastawionego na wszechstronną produkcję. Do określenia efektów ekonomicznych działu hodowli wykorzystano dane liczbowe tych przedsiębiorstw i wywiady bezpośrednie z pracownikami działu hodowli oraz z zarządem całego gospodarstwa. Przeprowadzono także rachunek symulacyjny, w którym założono, że dział hodowli jest niezależnym przedsiębiorstwem i rozlicza się z gospodarstwem na zasadach komercyjnych. Przyjęto, że dział hodowli sprzedaje wartość intelektualną w postaci materiału siewnego w stopniu „E”, a gospodarstwo rolne stanowi niejako przedsiębiorstwo nasienne, które sprzedaje nasienną produkcję towarową w stopniu „K”. Stwierdzono, że przy zachowaniu pełnego wewnętrznego rozliczenia działów hodowli roślin, a także pełnej ściągalności opłat hodowlanych w spółkach nasiennych hodowla łubinów jest działalnością wysoce opłacalną. Stwierdzony potencjał rozwojowy i produkcyjny wskazuje na możliwość wykorzystania tych roślin do zwiększenia samowystarczalności kraju w białko roślinne.

Phenolics exudation by imbibed seeds and roots of intact lupin plants (Lupinus albus L.) was studied during the first 4 days of growth by a new agar test with specific reagents for phenolics (Gibbs reagent, Naturstoffreagenz A). Comparative studies of the phenolics exudation reveal that legumes exude different phenolics (even if not qualitatively, then at least quantitatively) than oat. The exudation of phenolics starts very quickly after the imbibition of seeds and can be visualized as early as 24 h after sowing. In older seedlings, the exudation of phenolics can be detected along root zones and is influenced by nitrate and pH. At acidic pH, nitrate reduces phenolics exudation, but at pH 7.5 the exudation of phenolics becomes restricted to only some root zones. Nitrate must be present in the rooting media for at least 24 h to cause visible changes in the pattern of exudation at different pH values.

Two full copy cDNA sequences encoding chalcone synthase (CHS) were selected from a yellow lupin (Lupinus luteus L.) root and nodule cDNA library, and sequenced. Analysis of their open reading frames gave evidence that both encode the functional enzyme. Sequence alignment and phylogenetic studies on the DNA and protein level of these clones compared to the sequences of chalcone synthases from 54 other plant species reveal the possibility that lupin chalcone synthase is encoded by a multigene family consisting of at least two distinct genes that probably diverged by gene duplication. The duplication event is estimated to have taken place about 16 million years ago.
