Nova Planta Japonica (I)

In planta gene targeting.

The development of designed site-specific endonucleases boosted the establishment of gene targeting (GT) techniques in a row of different species. However, the methods described in plants require a highly efficient transformation and regeneration procedure and, therefore, can be applied to very few species. Here, we describe a highly efficient GT system that is suitable for all transformable pl...

Optically Thick Winds from Degenerate Dwarfs. I. Classical Nova of Populations I and II

Twenty six sequences of optically thick wind solutions have calculated which mimic time-dependent evolution of classical novae of populations I and II. The peak of the new opacity around log T = 5:2 due to iron lines is found to be strong enough to accelerate the winds even in very low iron abundance such as Z=0.001 for massive white dwarfs ( 0:8M ). The old population novae show the slow light...

Quark - Nova

We explore the scenario where the core of a neutron star (having experienced a transition to an up and down quark phase) shrinks into the equilibrated quark object after reaching strange quark matter saturation density (where a composition of up, down and strange quarks is the favored state of matter). The overlaying (envelope) material free-falls following the core contraction releasing upto 1...

In-planta transformation: recent advances

In-planta transformation is an efficient, quick and tissue culture independent system for crop plants improvement. In-planta transformation is a useful system for those plants that lack tissue culture and regeneration system. Therefore, the direct in-planta methods are commonly used for the transformation of many important genes into these plant species. The two most common Agrobacterium mediat...
