Germinal Centre Shutdown [PDF]

open access: yesFrontiers in Immunology, 2021
Germinal Centres (GCs) are transient structures in secondary lymphoid organs, where affinity maturation of B cells takes place following an infection. While GCs are responsible for protective antibody responses, dysregulated GC reactions are associated with autoimmune disease and B cell lymphoma.

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

open access: yesSeed Science Research, 2012
AbstractA 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. Vleeshouwerset al.(1995) realized that barriers between disciplines limited progress and through insightful conclusions in their paper ...

Germinal Centers [PDF]

open access: yesAnnual Review of Immunology, 2012
Germinal centers (GCs) were described more than 125 years ago as compartments within secondary lymphoid organs that contained mitotic cells. Since then, it has become clear that this structure is the site of B cell clonal expansion, somatic hypermutation, and affinity-based selection, the combination of which results in the production of high-affinity ...

Germination responses to light of four Neotropical forest tree species along an elevational gradient in the southern Central Andes [PDF]

open access: yes, 2020
Seed germination is a key part of plants' life cycle and is mostly affected by the genetic background, the environmental conditions experienced by the mother plant and the seedbed conditions.

Responses of germination to light and to far-red radiation—can they be predicted from diaspores size? [PDF]

open access: yes, 2020
This paper presents an update of a dataset of seed volumes previously released online and combines it with published data of the photoblastic response of germination of fruits or seeds (light or dark conditions), and of the effects of enhanced far-red ...

The germination of germanium [PDF]

open access: yesNature Chemistry, 2018
Shawn C. Burdette and Brett F. Thornton explore how germanium developed from a missing element in Mendeleev's periodic table to an enabler for the information age, while retaining a nomenclature oddity.

Effect of thermal shock and ruminal incubation on seed germination in Helianthemum apenninum L. Mill (Cistaceae) [PDF]

open access: yes, 2002
Effect of thermal shock and ruminal incubation on seed germination in Helianthemum apenninum (L.) Mill. (Cistaceae). Here, we analyse the effect of different treatments on seed germination in Helianthemum apenninum (L.) Mill.

DOF AFFECTING GERMINATION 2 is a positive regulator of light-mediated seed germination and is repressed by DOF AFFECTING GERMINATION 1 [PDF]

open access: yes, 2015
BACKGROUND: The transcription factor DOF AFFECTING GERMINATION1 (DAG1) is a repressor of the light-mediated seed germination process. DAG1 acts downstream PHYTOCHROME INTERACTING FACTOR3-LIKE 5 (PIL5), the master repressor, and negatively regulates ...

The guanine nucleotide exchange factor RIC8 regulates conidial germination through Gα proteins in Neurospora crassa. [PDF]

open access: yes, 2012
Heterotrimeric G protein signaling is essential for normal hyphal growth in the filamentous fungus Neurospora crassa. We have previously demonstrated that the non-receptor guanine nucleotide exchange factor RIC8 acts upstream of the Gα proteins GNA-1 and

Striga seed-germination activity of root exudates and compounds present in stems of Striga host and nonhost (trap crop) plants is reduced due to root colonization by arbuscular mycorrhizal fungi. [PDF]

open access: yes, 2009
Root colonization by arbuscular mycorrhizal (AM) fungi reduces stimulation of seed germination of the plant parasite Striga (Orobanchaceae). This reduction can affect not only host plants for Striga, resulting in a lower parasite incidence, but also ...
