Apples are specially trimmed
Time of Update: 2021-03-16
For this kind of branch in the transformation, should be mainly to "slow" mainly, extend the length of the branch stay, generally cut in the weak buds, increase the angle of the main branch branch, remove the back of the branch group, more left side, lower branch group, the implementation of the backbone of the branch ring cutting and other measures to control the transport of nutrients, promote flowering.

Nested PCR and RFLP Analysis Based on the 16S rRNA Gene
Time of Update: 2021-03-16
Current phytoplasma detection and identification methods are primarily based on nested polymerase chain reaction followed by restriction fragment length polymorphism analysis and gel electrophoresis.
These methods can potentially detect and differentiate all phytoplasmas including those previously not described.

Shedding (abscission)
Time of Update: 2021-03-16
It has been pointed out that leaf aging can lead to its shedding, is due to the reduction of the amount of leaf synthetic growth hormone, through the leaf handle output is also reduced, so that the content of out-of-area growth hormone decreased, this decline can make the out-of-area cells more sensitive to ethylene, causing the effect of the above-mentioned ethylene.

DoseResponse to and Systemic Movement of Dexamethasone in the GVG-Inducible Transgene System in Arabidopsis
Time of Update: 2021-03-16
We have developed Arabidopsis plants using this inducible system to drive expression of a bacterial type III effector protein.
The effector, AvrRpm1, elicits either strong cell death or weak cell death and chlorosis depending on the genetic background of the plant.
