(Cambridge University Press. Cambridge, UK, 2001-09-01)A recombinant protein (approximately 38 kDa by SDS/PAGE), induced by expression in Escherichia coli of a cDNA encoding a 1-aminocyclopropane-1-carboxylate oxidase (ACO) isolated from embryonic axes of Cicer arietinum, was ...
-
(Cambridge University Press. Cambridge, UK, 1997-06-01)How some plant cells can survive a period of desiccation to live again when other cells will die, was the theme of the recent Workshop in the mountain retreat of Franschhoek, near Cape Town, South Africa. Sixty-two biochemists ...
-
(Cambridge University Press. Cambridge, UK, 1998-12-01)Seed dormancy and germination of Senna marilandica and S. obtusifolia were compared in greenhouse and laboratory studies. About 90% of the S. obtusifolia seeds were green and had hard seed coat dormancy, whereas the other ...
-
(Cambridge University Press. Cambridge, UK, 1997-03-01)Solidago shortii is endemic to a small area in northcentral Kentucky (USA), whereas two of its sympatric congeners, S. altissima and S. nemoralis, are geographically widespread. Seeds (achenes) of S. shortii (0.370 mg) are ...
-
(Cambridge University Press. Cambridge, UK, 1997-06-01)Seeds of the narrow-endemic Solidago shortii and of the geographically-widespread S. altissima and S. nemoralis collected and buried in 1992 and 1993 were incubated in light and in darkness at 15/6°, 20/10°, 25/15°, 30/15° ...
-
(Cambridge University Press. Cambridge, UK, 1997-09-01)Regardless of whether or not seeds of the geographically-widespread Solidago altissima and S. nemoralis were exposed to light in autumn, those ‘dispersed’ in autumn (15/°C) or winter (5°C) required 12 weeks of light in ...
-
(Cambridge University Press. Cambridge, UK, 1997-09-01)Seeds of the narrow-endemic Solidago shortii and of the geographically-widespread S. altissima and S. nemoralis buried in December 1993 were exhumed in June 1995 and given 10 cycles of 1 day wet/5 days dry, 9 of 2/5, 8 of ...
-
(Cambridge University Press. Cambridge, UK, 1997-09-01)The effect of dry storage under ambient laboratory conditions on after-ripening and survivorship was tested on seeds of the geographically-widespread Solidago altissima and S. nemoralis and the narrow-endemic S. shortii. ...
-
(Cambridge University Press. Cambridge, UK, 1998-03-01)Seeds of the geographically-widespread Solidago altissima and S. nemoralis and the narrow-endemic S. shortii were buried in pots of soil and placed in a glasshouse without temperature control. After 0.3–4.3 years of burial, ...
-
(Cambridge University Press. Cambridge, UK, 1995-12-01)Dehydrin and QP47, proteins present in mature pea seeds (Pisum sativum), have been proposed to play protective roles during desiccation. To identify possible relationships between these proteins and desiccation tolerance, ...
-
(Cambridge University Press. Cambridge, UK, 1995-06-01)Imbibed embryos of after-ripened and secondarily thermo- and FR-dormant Agrostemma githago seeds were investigated as to their ability to synthesize DNA, RNA and proteins with the aim of finding characteristic differences ...
-
(Cambridge University Press. Cambridge, UK, 1995-06-01)The emphasis of modern dormancy research is almost entirely on the form of dormancy that is acquired during seed development, primary dormancy. Abscisic acid (ABA) appears to be intimately involved in its regulation. The ...
-
(Cambridge University Press. Cambridge, UK, 1997-09-01)Electron paramagnetic resonance studies of high vigour (99% viable) and low vigour (38% viable) dry embryos of rice seeds (Oryza sativa L.) stored in a natural (warm and humid) environment were carried out. Loss in viability ...
-
(Cambridge University Press. Cambridge, UK, 1996-12-01)Bromus tectorum L. is an invasive winter annual grass with seeds that lose dormancy through the process of dry after-ripening. This paper proposes a model for after-ripening of B. tectorum seeds based on the concept of ...
-
(Cambridge University Press. Cambridge, UK, 1994-03-01)Some of the seed-evolved volatiles, which were mainly composed of methanol, acetaldehyde, ethanol and acetone, caused the loss of seed germinability during storage. In general, the deleterious effects of the volatiles ...
-
(Cambridge University Press. Cambridge, UK, 1998-12-01)The longevity of neem, Azadirachta indica, seeds from African Sahelian (Burkina Faso) and Asian (Sri Lanka) provenances was studied over two years of storage under different conditions of moisture and temperature. After ...
-
(Cambridge University Press. Cambridge, UK, 1991-12-01)The variation for protein content has been assessed in a series of pea (Pisum sativum L.) lines differing in mean seed size. The range of seed size within each genotype was manipulated by growing the plants in different ...
-
(Cambridge University Press. Cambridge, UK, 2008-06-01)The ability to initiate radicle elongation, or germination potential, occurs in developing embryos before the completion of seed maturation. Green embryos after the walking-stick stage in developing Arabidopsis thaliana ...
-
(Cambridge University Press. Cambridge, UK, 2000-03-01)Priming treatment of sunflower (Helianthus annuus L., cv Briosol) seeds for 7 days at 15°C with a polyethylene glycol solution at −2.0 MPa strongly improved their subsequent germination at 15°C on water. This stimulatory ...
-
(Cambridge University Press. Cambridge, UK, 1994-03-01)DNA synthesis in organelles seems to be an early event during maize germination. Mitochondria and plastids from maize embryo axes have been separated using differential and gradient centrifugations and DNA polymerase ...
