Evolution of repetitive DNA in angiosperms: examples from Nicotiana allopolyploids [PDF]
PhDAllopolyploidy, interspecific hybridisation coupled with genome multiplication, is a prevailing force in the evolution of angiosperms. This thesis examines the consequences of allopolyploidy at the genomic level.

An Endophytic Trichoderma Strain Promotes Growth of Its Hosts and Defends Against Pathogen Attack
Plants host numerous endophytic microbes which promote plant performance, in particular under stress. A new endophytic fungus was isolated from the leaves of a deciduous wood tree Leucas aspera.

Native bacterial endophytes promote host growth in a species-specific manner; phytohormone manipulations do not result in common growth responses. [PDF]
BackgroundAll plants in nature harbor a diverse community of endophytic bacteria which can positively affect host plant growth. Changes in plant growth frequently reflect alterations in phytohormone homoeostasis by plant-growth-promoting (PGP ...

The effect of polyploidy and hybridization on the evolution of floral colour in Nicotiana (Solanaceae). [PDF]
Speciation in angiosperms can be accompanied by changes in floral colour that may influence pollinator preference and reproductive isolation. This study investigates whether changes in floral colour can accompany polyploid and homoploid hybridization ...

CELL CYCLE KINETICS AND DEVELOPMENT OF HYDRA ATTENUATA [PDF]
The differentiation of nerve cells and nematocytes in Hydra attenuata has been investigated by labelling interstitial cell precursors with PHJthymidine and following by autoradiography the appearance of labelled, newly differentiated cells.

Biosynthesis, regulation and herbivore defense function of triterpenes from Nicotiana attenuata
In this study, the biosynthesis, regulation, and defense function of triterpenes in a wild tobacco plant Nicotiana attenuata were elucidated. We discovered that two oxidosqualene cyclases, NaOSC1 and NaOSC2, are involved in the synthesis of the ...

Determination of Nectar Nicotine Concentration in N. attenuata
In this protocol, the determination of the nicotine concentration in nectar of Nicotiana attenuata is described. This method is applicable for the investigation of small amounts of nectar (above 1 μl).

Background Tobacco rattle virus (TRV) based virus-induced gene silencing (VIGS), a widely used functional genomics tool, requires growth temperatures typically lower than those of the plant’s native environment.

Increases in pathogenesis-related (PR) transcripts are commonly interpreted as evidence of plants' resistance responses to pathogens; however, few studies have examined whether increases in PR proteins protect plants growing under natural conditions ...
