Hormonome Dynamics During Microgametogenesis in Different Nicotiana Species
Plant microgametogenesis involves stages leading to the progressive development of unicellular microspores into mature pollen. Despite the active and continuing interest in the study of male reproductive development, little is still known about the ...

Mature pollen grain represents a highly desiccated structure with an extremely tough cell wall. Thanks to it, it resists common proteomic protocols. Instead, a robust homogenization has to be performed since proteins are needed to burst out of the cell ...

The rising tide of photographs: Not drowning but waving?
Concerns about the huge quantities of photographs circulating in digital networks have led some to proclaim that we are now drowning in images. This article surveys these anxieties by examining the work of artists who use photography’s scale, and ...

Understanding emissions of ammonia from buildings and the application of fertilizers: an example from Poland [PDF]
A Europe-wide dynamic ammonia (NH3) emissions model has been applied for one of the large agricultural countries in Europe, and its sensitivity on the distribution of emissions among different agricultural functions was analyzed by comparing with ...

Allergenic pollen and pollen allergy in Europe
The allergenic content of the atmosphere varies according to climate, geography and vegetation. Data on the presence and prevalence of allergenic airborne pollens, obtained from both aerobiological studies and allergological investigations, make it possible to design pollen calendars with the approximate flowering period of the plants in the sampling ...

Pollen Sporoplasts: Dissolution of Pollen Walls [PDF]
4-Methylmorpholine N-oxide monohydrate (MMNO.H(2)O), a potent solvent for polysaccharides, is an effective vehicle for release of membrane-enclosed male gametophytes (sporoplasts) from spore walls. This release occurs in minutes when pollen (Lilium longiflorum Thunb.) is suspended in a melt of MMNO.H(2)O at 75 degrees C. Continued heating at 75 degrees

Functional expression and subcellular localization of pea polymorphic isoflavone synthase CYP93C18
Isoflavone synthase (IFS; CYP93C) plays a key role in the biosynthesis of phenolic secondary metabolites, isoflavonoids. These compounds, which are well-known for their benefits to human health and plant defence, are produced mostly in legumes.
