Cell cycle regulation during growth-dormancy cycles in pea axillary buds
Plant Molecular Biology, 1995Accumulation patterns of mRNAs corresponding to histones H2A and H4, ribosomal protein genes rpL27 and rpL34, MAP kinase, cdc2 kinase and cyclin B were analyzed during growth-dormancy cycles in pea (Pisum sativum cv. Alaska) axillary buds. The level of each of these mRNAs was low in dormant buds on intact plants, increased when buds were stimulated to ...

Variation between Emex australis populations in seed dormancy/non‐dormancy cycles
Australian Journal of Ecology, 1993Abstract Seeds of four Western Australian accessions of Emex australis were stored outside and their germinability tested at 4–6 week intervals for 22 months. Accessions showed cyclical behaviour in germinability, with peaks in autumn/early winter and troughs in spring/summer.

Hydration cycles and overcoming dormancy in Butia capitata (Arecaceae) diaspores
Trees, 2021Hydration cycles promote embryo physiological changes, favoring overcoming dormancy in Butia capitata seed banks. Dormant seeds can spend many years in soil seed banks while subject to successive hydration and dehydration cycles (HC). Our knowledge concerning the effects of HC on seed survival and on overcoming dormancy is still limited, especially ...

Rapid Cycling of Potato Tuber Generations by Overcoming Dormancy
American Journal of Potato Research, 2014Dormancy hinders progress in attempts to fast track potato tuber generations. In this study, we evaluated the ability of gibberellic acid (GA) to overcome dormancy in freshly harvested tubers of 11 potato cultivars in 2 years of field trials. Tubers were wounded and dipped in 0, 10, 100, and 1,000 ppm GA.

Cell cycle inHelianthus tuberosus tuber tissue in relation to dormancy [PDF]
Protoplasma, 1982 Observations are presented on the patterns of DNA synthesis and mitotic activity in medullary parenchyma cells excised from tubers ofHelianthus tuberosus in four different periods of dormancy. Dormancy break (activation) was induced byin vitro culture on media added with 2,4-dichlorophenoxyacetic acid.

Plant and Soil, 2021
Seed dormancy and the formation of a soil seed bank is important plant regeneration strategies, especially if the environment is unpredictable. The present research explores how environmental factors control seed dormancy release, and how seed dormancy is related to the soil seed bank and regeneration of the perennial Aquilegia oxysepala.

Primary dormancy and annual dormancy cycles in seeds of six temperate wetland sedges
Aquatic Botany, 1997Abstract The effects of dry after-ripening and burial in the soil on seed germination of six temperate wetland Carex spp. were investigated. Freshly matured seeds, seeds stored dry for 4 or 8 weeks, and seeds buried at 7-cm depth in a small woodlot, and exhumed at approximately bimonthly intervals over a 2-year period, were tested under a ...

Regulation of Seed Dormancy Cycling in Seasonal Field Environments
2015Seeds respond to a range of environmental signals, using them for both temporal and spatial sensing to alter their depth of dormancy to ensure germination takes place in a favorable habitat and climate space, and in the correct season. Many signals have the potential to inform the seed about its environment; we consider the effects of temperature as a ...

The Annual Dormancy Cycle in Buried Weed Seeds: A Continuum
BioScience, 1985The classic studies of Brenchley and Warington (1930) and numerous other investigations have demonstrated that large reserves (pools) of weed seeds accumulate in arable soils. Work reviewed by Kropad (1966) and Roberts (1981) shows that the number of seeds per m2 in the upper 15-25 cm of soil in cultivated fields may be as high as 70,000-90,000, and up

The localization of the Kip-related proteins to meristematic regions suggests that these proteins might be associated with dormancy regulation. Additionally, the localization of chromatin remodeling to specific genes and loci may reveal the important regulation mechanisms for the dormant state.
