Gene Activation by T-DNA Tagging
Time of Update: 2021-03-13
T- DNA tagging has proven a powerful genetic approach for the isolation of novel plant genes.
Compared with other approaches to gene isolation (for a review,see ref.
Furthermore, T-DNA is an ideal gene tag, as it has the potential to insert preferentially into potentially transcribed regions of the genome ( 5 ).

Seedless fruit
Time of Update: 2021-03-13
Bananas, for example, can develop directly into unseeded fruit without pollination and fertilization of female flowers in the lower part of the spiked flower sequence under natural conditions.
In addition to bananas, some varieties of citrus, persimmon, melon and grape can also form seedless fruits due to monogamical syringe under natural conditions.

小孔律（law of small pore）
Time of Update: 2021-03-13
This is because there is an edge effect when the gas molecules spread outward from the hole surface.
The edge effect can be expressed, and there must be a certain distance between the holes so that the diffusers do not interfere with each other.

Prunus mume
Time of Update: 2021-03-13
Flower leaves open, single or two out, barrel bell-shaped, petals are mostly white or pale red, fragrant.
Depending on the fruit color when harvesting, can be divided into white plum (green white), green plum (green), flower plum (with red) and other types.

Pollen tube
Time of Update: 2021-03-13
Generally each pollen grain germinates to produce a pollen tube, with a poly-germination hole pollen grain can start to grow several pollen tubes at the same time, but in the end only one continues to grow.
The cytoste behind the cap area contains a variety of cytocytes, which are associated with the growth of pollen tubes.

Binding Studies
Time of Update: 2021-03-13
The primary stimulus initiating the sequence of events leading to such responses is the interaction of the hormone with its receptor protein.
In general, receptors may be either membrane-associated or soluble (or solubilized) and this chapter deals with one binding technique suitable for each class.
