13. Development of two sequence-specific PCR markers linked to the le gene that reduces pod shattering in narrow-leafed Lupin (Lupinus angustifolius L.)
Wild types of narrow-leaf lupin (Lupinus angustifolius L.) have seed pods that shatter upon maturity, leading to the loss of their seeds before or during the harvest process. Two recessive genes have been incorporated into domesticated cultivars of this species to maximize harvest-ability of the produce. One of these genes is called lentus (le). Two microsat

14. Performance of lettuce (Lactuca sativa L.) intercropped with different green manures / Desempenho de alface (Lactuca sativa L.) consorciada com diferentes adubos verdes
The agricultural production systems currently used are in most cases ecologically impacting and use high amounts of natural resources. Within this context, vegetable production is an activity characterized by intensive land use and high demand for farm inputs, requiring the adoption of an agroecological management approach for sustaining its production. Thus

15. Atividade e diversidade da biomassa microbiana em diferentes sistemas de manejo do solo e de culturas no norte do Estado do Parana / Activity and diversity of microbial biomass under different soil and crop management systems in the north of the state of Parana (Brazil)
The microbial biomass carbon (MB-C) and nitrogen (MB-N), basal respiration and metabolic quotient (qCO2) were evaluated in a Rhodic Eutrudox of the North Region of the State of Paraná under different soil and crop management systems. The experimental area was established in 1988/1989 at the experimental station of Embrapa Soja, Londrina, Paraná, and consis

16. Efficiency of different crops and corn hybrids on the use of phosphorus in cerrado soil. / Eficiências de diferentes culturas e híbridos de milho quanto a utilização de fósforo em solos de cerrado.
The Cerrado (Savannah) region has been one of main agriculture expansion area in Brasil, presenting favorable characteristics, but also limitations to crop production, mainly the low soil phophorus content and availability. The objective of the work was to evaluate the mainly recommended maize hybrids for cerrado region on the ability to absorb poorly-availa

17. EFFECTS OF ROOT-DERIVED ORGANIC ACIDS ON METAL SPECIATION IN SOIL SOLUTION AND BIOAVAILABILITY
Several plant species can exude relative large amounts of low-molecular-weight organic acids (LMWOAs) into the hizosphere. Limited information is available about the effects of these compounds on the mobilization and bioavailability of trace metals for plants. The objective of this study was to measure the impact of in situ-produced and added LMWOAs on metal

18. Transfer RNA methyltransferases from yellow lupin seeds: purification and properties.
tRNA methyltransferases from extract of yellow lupin seeds were purified over 300-fold by the methods based on hydrophobic and affinity chromatography. However, in the most active fractions the methylating enzymes were over 2000 purified. The purified enzyme fractions catalysed the formation of 1-methyladenine and 5-methylcytosine using E. coli B and B. subt

19. Sulfur Assimilation in Developing Lupin Cotyledons Could Contribute Significantly to the Accumulation of Organic Sulfur Reserves in the Seed
It is currently assumed that the assimilation of sulfur into reduced forms occurs predominantly in the leaves of plants. However, developing seeds have a strong requirement for sulfur amino acids for storage protein synthesis. We have assessed the capacity of developing seeds of narrow-leaf lupin (Lupinus angustifolius) for sulfur assimilation. Cotyledons of

20. Limits to Sulfur Accumulation in Transgenic Lupin Seeds Expressing a Foreign Sulfur-Rich Protein
The low sulfur amino acid content of legume seeds restricts their nutritive value for animals. We have investigated the limitations to the accumulation of sulfur amino acids in the storage proteins of narrow leaf lupin (Lupinus angustifolius) seeds. Variation in sulfur supply to lupin plants affected the sulfur amino acid accumulation in the mature seed. How

21. Molecular Control of Acid Phosphatase Secretion into the Rhizosphere of Proteoid Roots from Phosphorus-Stressed White Lupin1
White lupin (Lupinus albus) grown under P deficiency displays a suite of highly coordinated adaptive responses. Included among these is secretion of copious amounts of acid phosphatase (APase). Although numerous reports document that plants secrete APases in response to P deficiency, little is known of the biochemical and molecular events involved in this pr

22. Organization and nucleotide sequence of nuclear 5S rRNA genes in yellow lupin (Lupinus luteus).
Genomic blots of yellow lupin (Lupinus luteus) DNA digested with restriction nucleases and probed with 32P-labelled Lupinus 5S RNA reveal that 5S DNA is organized as tandemly repeated sequences of one size class, 342 bp. The DNA is extensively methylated. Two cloned BamHI ribosomal repeats were sequenced, revealing sequence divergence within both the coding

24. Studies with Detached Lupin Root Nodules in Culture: I. Maintenance and Induction of Acetylene Reduction Activity
A method has been developed for culturing detached nitrogen-fixing root nodules of lupin (Lupinus angustifolius L.) on a simple nutrient medium. Under the best conditions devised, the acetylene reduction activity of mature detached nodules was maintained at 10 to 25 nmoles of ethylene hr−1 mg−1 fresh weight for 3 days. Under the same culture conditions,
