-
(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, 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, 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, 1995-06-01)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, 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, 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, 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, 1997-06-01)Plants undergo a series of physiological, biochemical and molecular changes in response to adverse environmental conditions or stresses such as drought, low temperature or high salt. Several genes and their corresponding ...
-
(Cambridge University Press. Cambridge, UK, 1999-01-01)A suite of mechanisms or processes that together have been implicated in the acquisition and maintenance of desiccation tolerance in orthodox seeds is discussed in the context of the behaviour of desiccation-sensitive ...
-
(Cambridge University Press. Cambridge, UK, 1999-03-01)
-
(Cambridge University Press. Cambridge, UK, 2008-06-01)In vitro techniques are essential for Striga research and the development of appropriate control methods. In the laboratory, pre-screening of non-host or false-host plants of Striga for trap cropping or the screening of ...
-
(Cambridge University Press. Cambridge, UK, 2001-03-01)A model has been developed to simulate the annual dormancy cycle of seeds of light-requiring species in the seed bank and the germination of exhumed seeds after irradiation. Simulation of dormancy and germination is based ...
-
(Cambridge University Press. Cambridge, UK, 1998-09-01)Seed development is a series of events involving cell division, followed by cell differentiation and storage activity In legume cotyledons, cell differentiation starts in certain regions and gradually spreads to other ...
-
(Cambridge University Press. Cambridge, UK, 2006-12-01)
-
(Cambridge University Press. Cambridge, UK, 1999-01-01)The cell cycle is regulated, at least partially, by protein phosphorylation, activity that is carried out by a series of calcium-independent protein kinases among which the p34cdc2 kinase plays a preponderant role. The ...
