Pollen Tube and Plant Reproduction. [PDF]

Int J Mol Sci, 2019
The pollen tube was a fundamental step forward in the evolution of terrestrial plants; in fact, it allowed plants to liberate themselves from water demand during reproduction [...]

Evolution of plant reproduction: from fusion and dispersal to interaction and communication [PDF]

, 2009
Based on the existing data concerning the evolution of the sexual reproduction, it is argued that the processes of sex differentiation and interactions play a key role in evolution. From the beginning environment and organism are unified.

Biologically active Phytophthora mating hormone prepared by catalytic asymmetric total synthesis [PDF]

, 2008
A Phytophthora mating hormone with an array of 1,5-stereogenic centers has been synthesized by using our recently developed methodology of catalytic enantioselective conjugate addition of Grignard reagents. We applied this methodology in a diastereo- and

The effect of insect herbivory on the growth and fitness of introduced Verbascum thapsus L. [PDF]

, 2013
A majority of the plant species that are introduced into new ranges either do not become established, or become naturalized yet do not attain high densities and are thus considered ecologically and economically unproblematic. The factors that limit these

Sustainable deployment of QTLs conferring quantitative resistance to crops: first lessons from a stochastic model [PDF]

, 2014
Quantitative plant disease resistance is believed to be more durable than qualitative resistance, since it exerts less selective pressure on the pathogens.

Plant Reproduction [PDF]

The Plant Cell, 2002
In a letter addressed to Joseph Hooker in 1879, Charles Darwin referred to the rapid development and diversification of the flowering plants in recent geological times as an “abominable mystery.” The mystery of the origin of angiosperms, the development of floral characters, and the ...

Finished Genome of the Fungal Wheat Pathogen Mycosphaerella graminicola Reveals Dispensome Structure, Chromosome Plasticity, and Stealth Pathogenesis [PDF]

, 2011
The plant-pathogenic fungus Mycosphaerella graminicola (asexual stage: Septoria tritici) causes septoria tritici blotch, a disease that greatly reduces the yield and quality of wheat.

Understanding plant reproductive diversity [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2010
Flowering plants display spectacular floral diversity and a bewildering array of reproductive adaptations that promote mating, particularly outbreeding. A striking feature of this diversity is that related species often differ in pollination and mating systems, and intraspecific variation in sexual traits is not unusual, especially among herbaceous ...
