Exogenous spermidine improves seed germination of sweet corn via involvement in phytohormone interactions, H2O2 and relevant gene expression

open access: yesBMC Plant Biology, 2017
The low seed vigor and poor field emergence are main factors that restricting the extension of sweet corn in China. Spermidine (Spd) plays an important role in plant growth and development, but little is known about the effect of Spd on sweet corn seed ...

Germinable seeds and periodicity of germination in annual grasslands

open access: yesHilgardia, 1981
Germinable seed reserves and periodicity of germination of the plant species in annual communities were periodically and intensively sampled from 1974 through 1977 at the Sierra Foothill Range Field Station (SFRFS) and the U.S. Forest Service’s San Joaquin Experimental Range (SJER).

Transforming Plastic Waste into Strain Sensors: Multifunctional Upcycled TPEE Elastomers with MXene Multilayer Assemblies

open access: yesAdvanced Materials Technologies, EarlyView.
A sustainable approach is reported for upcycling PET waste into thermoplastic polyester elastomer (TPEE)‐based films with advanced properties, specifically designed for applications in strain sensing, conductivity, and photothermal response. Through a layer‐by‐layer deposition technique, TPEE films are fabricated with bio‐compatible chitosan (CH) or ...

The NF-YC–RGL2 module integrates GA and ABA signalling to regulate seed germination in Arabidopsis

open access: yesNature Communications, 2016
The antagonistic crosstalk between gibberellic acid (GA) and abscisic acid (ABA) plays a pivotal role in the modulation of seed germination. However, the molecular mechanism of such phytohormone interaction remains largely elusive.

The Biology of the Germinal Center [PDF]

open access: yesHematology, 2007
The immune system requires the production of high affinity antibodies of different subclasses to accomplish its many effector functions. Specific steps in B-cell ontogeny that occur within germinal centers of secondary lymphoid organs create much of the diversity in the immune system.

Etude de la germination des graines d'Acacia tortilis sous différentes contraintes abiotiques [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2010
Study of Acacia tortilis seed germination under different abiotic constraints. Since Tunisian acacia populations are threatened by regression, we analyzed as a preliminary study the germination behavior of the species in order to plan subsequently for a ...

Application of a Dynamic Semitransparent Agrivoltaic Panel for Controlling Sunlight Allocation to Solar Cells and Crops

open access: yesAdvanced Sustainable Systems, EarlyView.
Effects of dynamic agrivoltaic semitransparency controls on cucumber seedling growth are assessed for this study using a micro‐cell photovoltaic panel. Seedling growth with 9:30–14:30 agrivoltaic shading is comparable to that without shading. The dynamic shading regulates the electrical energy and crop production allocation.
