Seed dormancy and germination [PDF]

open access: yes, 2002
Seed dormancy allows seeds to overcome periods that are unfavourable for seedling established and is therefore important for plant ecology and agriculture. Several processes are known to be involved in the induction of dormancy and in the switch from the

To germinate or not to germinate : a question of dormancy relief not germination stimulation [PDF]

open access: yes, 2012
A common understanding of the control of germination through dormancy is essential for effective communication between seed scientists whether they are ecologists, physiologists or molecular biologists. Vleeshouwers et al.

What Can Be Learnt about Disease Progression in Breast Cancer Dormancy from Relapse Data? [PDF]

open access: yes, 2013
Breast cancer patients have an anomalously high rate of relapse many years-up to 25 years-after apparently curative surgery removed the primary tumour.

Temperature, light and nitrate sensing coordinate Arabidopsis seed dormancy cycling resulting in winter and summer annual phenotypes [PDF]

open access: yes, 2013
Seeds use environmental cues to sense the seasons and their surroundings to initiate the plants life cycle. Dormancy cycling underlying this process is extensively described, but the molecular mechanism is largely unknown.

Environment sensing in spring-dispersed seeds of a winter annual Arabidopsis influences the regulation of dormancy to align germination potential with seasonal changes [PDF]

open access: yes, 2014
Seed dormancy cycling plays a crucial role in the lifecycle timing of many plants. Little is known of how the seeds respond to the soil seed bank environment following dispersal in spring into the short-term seed bank before seedling emergence in autumn.

16S rRNA/rRNA Gene Ratios and Cell Activity Staining Reveal Consistent Patterns of Microbial Activity in Plant-Associated Soil

open access: yesmSystems, 2019
At any given time, only a subset of microbial community members are active in their environment. The others are in a state of dormancy, with strongly reduced metabolic rates.

Incorporating dormancy in dynamic microbial community models [PDF]

open access: yes, 2011
Biogeochemical activity in natural and engineered systems depends on the abundances, functional capabilities and physiological states of the indigenous microorganisms.

Understanding the mechanisms behind onion bulb dormancy in relation to the potential for improved onion storage [PDF]

open access: yes, 2006
Onion (Allium cepa L.) is the most economically important Allium crop. Onion cultivars adapted for growth in temperate regions require long days for bulb initiation, so the summer crop is stored over-winter.

Do soil microbes and abrasion by soil particles influence persistence and loss of physical dormancy in seeds of tropical pioneers?

open access: yesFrontiers in Plant Science, 2015
Germination from the soil seed bank (SSB) is an important determinant of species composition in tropical forest gaps, with seed persistence in the SSB allowing trees to recruit even decades after dispersal.

MICROBIAL DIVERSITY THROUGH SPACE AND TIME: DISPERSAL AND DORMANCY IN MICROBIAL COMMUNITIES [PDF]

open access: yes, 2020
Thesis (Ph.D.) - Indiana University, Biology/University Graduate School, 2020Microorganisms are the most diverse organisms on the planet. Understanding the processes by which they are assembled into communities across space and time is a primary goal of ...
