Partitioning of carbon and nitrogen and the nutrition of root and shoot apex in a nodulated legume.

Plant physiology

Layzell DB, Pate JS, Atkins CA, Canvin DT.
PMID: 16661628
Plant Physiol. 1981 Jan;67(1):30-6. doi: 10.1104/pp.67.1.30.

Empirically based models depicting exchanges of C, N, and H(2)O in phloem and xylem among organs of nodulated white lupin (Lupinus albus cv Ultra) were constructed for the interval 51 to 58 days after sowing. Information was incorporated on...

Synthesis, Storage, and Utilization of Amino Compounds in White Lupin (Lupinus albus L.).

Plant physiology

Pate JS, Atkins CA, Herridge DF, Layzell DB.
PMID: 16661629
Plant Physiol. 1981 Jan;67(1):37-42. doi: 10.1104/pp.67.1.37.

Changes in total N and in free amino compounds were followed during growth of nodulated white lupin. Leaflets contained the greatest fraction of plant N but had lower proportions (1 to 4%) of their N in soluble amino form...

Amino Acid transport and metabolism in relation to the nitrogen economy of a legume leaf.

Plant physiology

Atkins CA, Pate JS, Peoples MB, Joy KW.
PMID: 16662917
Plant Physiol. 1983 Apr;71(4):841-8. doi: 10.1104/pp.71.4.841.

Net balances of amino acids were constructed for stages of development of a leaf of white lupin (Lupinus albus L.) using data on the N economy of the leaf, its exchanges of amino acids through xylem and phloem, and...

Diurnal variation in the functioning of cowpea nodules.

Plant physiology

Rainbird RM, Atkins CA, Pate JS.
PMID: 16662998
Plant Physiol. 1983 Jun;72(2):308-12. doi: 10.1104/pp.72.2.308.

Nitrogenase (EC 1.7.99.2) activity of nodules of cowpea (Vigna unguiculata [L.] Walp), maintained under conditions of a 12-hour day at 30 degrees C and 800 to 1,000 microeinsteins per square meter per second (photosynthetically active radiation) and a 12-hour...

Nutrition of a developing legume fruit: functional economy in terms of carbon, nitrogen, water.

Plant physiology

Pate JS, Sharkey PJ, Atkins CA.
PMID: 16659881
Plant Physiol. 1977 Mar;59(3):506-10. doi: 10.1104/pp.59.3.506.

The economy of functioning of the developing fruit of white lupin (Lupinus albus L.) is assessed quantitatively in relation to intake and usage of carbon, nitrogen, and water. Of every 100 units of carbon imported from the parent plant,...

Carbon Dioxide Fixation in the Carbon Economy of Developing Seeds of Lupinus albus (L.).

Plant physiology

Atkins CA.
PMID: 16660544
Plant Physiol. 1978 Oct;62(4):486-90. doi: 10.1104/pp.62.4.486.

The effects of CO(2) concentration and illumination on net gas exchange and the pathway of (14)CO(2) fixation in detached seeds from developing fruits of Lupinus albus (L.) have been studied.Increasing the CO(2) concentration in the surrounding atmosphere (from 0.03...

Economy of Carbon and Nitrogen in a Nodulated and Nonnodulated (NO(3)-grown) Legume.

Plant physiology

Pate JS, Layzell DB, Atkins CA.
PMID: 16661097
Plant Physiol. 1979 Dec;64(6):1083-8. doi: 10.1104/pp.64.6.1083.

Partitioning and utilization of assimilated C and N were compared in nonnodulated, NO(3)-fed and nodulated, N(2)-fed plants of white lupin (Lupinus albus L.). The NO(3) regime used (5 millimolar NO(3)) promoted closely similar rates of growth and N assimilation...

Pathways of Nitrogen Assimilation in Cowpea Nodules Studied using N(2) and Allopurinol.

Plant physiology

Atkins CA, Storer PJ, Pate JS.
PMID: 16665867
Plant Physiol. 1988 Jan;86(1):204-7. doi: 10.1104/pp.86.1.204.

In the presence of 0.5 millimolar allopurinol (4-hydroxypyrazolo [3,4-d]pyrimidine), an inhibitor of NAD:xanthine oxidoreductase (EC 1.2.3.2), intact attached nodules of cowpea (Vigna unguiculata L. Walp. cv Vita 3) formed [(15)N]xanthine from (15)N(2) at rates equivalent to those of ureide...

In from the cold: prospects for conversion of the defense industrial base.

Science (New York, N.Y.)
