Hayward Cultured in Vitro

An efficient procedure for shoot regeneration was obtained by endosperm culture in Actinidia deliciosa cv. Hayward. Mature endosperm cultured on MS medium supplemented with 2 mg/l 2,4-D and 5 mg/l kinetin developed callus with 80% efficiency. Callus was transferred on MS medium containing different plant growth regulators (2,4-D, TDZ, IAA, NAA, BAP, kinetin, 2iP) for regeneration. There were si...

There have recently been moves afoot among evolutionary biologists to stop speaking of ‘Darwin’s theory of evolution’ and, instead, to call it ‘Darwin’s law of evolution’.

The underlying assumption is that the use of the word ‘La...

As a flexible needle with a bevel tip is pushed through soft tissue, the asymmetry of the tip causes the needle to bend. We propose that, by using nonholonomic kinematics, control, and path planning, an appropriately designed needle can be steered through tissue to reach a specified 3D target. Such steering capability could enhance targeting accuracy and may improve outcomes for percutaneous th...
