PCR and RFLP Analyses Based on the Ribosomal Protein Operon
Time of Update: 2021-03-13
RFLP analysis of amplicons obtained by group- or subgroup-specificrp gene-based primers is used for finer differentiation of phytoplasma strains within a given group or subgroup.
Therp gene-based classification not only readily resolves 16Sr subgroups within a given 16Sr group, but also provides finer differentiation of closely related phytoplasma strains.

Investigating Transgene Integration and Organization in Cotton (Gossypium hirsutum L.) Genome
Time of Update: 2021-03-13
For multiple copy insertions into the same site (complex loci), transgene/transgene junctions (including canonical and truncated T-DNA and transgene involved vector backbone sequences) are characterized by PCR and sequencing.
Distribution of T-DNA insertion in cotton genome is evaluated by analysis of transgene flanking sequences.

Gramineae
Time of Update: 2021-03-13
Leaves are mutually produced, two columns, consisting of leaves and leaves wrapped in straw.
In small spikes, they are then lined up in conical, total, spike or head-shaped flower sequences.

Plant Single Cell Sampling
Time of Update: 2021-03-13
Plant single cell sampling and analysis allows the determination of solute concentrations in individual cells and tissues.
In this chapter, some selected single cell sampling and analysis methods are described in detail, and their advantages and possible pitfalls discussed.

Experiment 14 Identification of volatile elements in plant tissue
Time of Update: 2021-03-13
pb(Ac) 2 H 2 S→PbS↓ 2HAc 2． Ba(OH) 2 CO 2 →BaCO 3 ↓ H 2 O 3． 2K 2 (HgI 4 ) 3NAaOH NH 3 → NH 2 Hg 2 O 4KI 3 From these reactions NaI 2H O can identify the presence of H 2 S, CO 2 , and NH 3 to demonstrate the volatile elements contained in plant tissue.

Factory production of new varieties of plants
Time of Update: 2021-03-13
If we use pre-cultured plant cell protosomes for sophyte fusion, we can also quickly obtain a large number of hybrid cells.
addition, pollen cell protosumin culture and chromosomal double technology provides excellent technical means for rapid purification of specific plant line.

Perennial Ryegrass (Lolium perenne L.)
Time of Update: 2021-03-13
The synthetic green fluorescent protein (sgfpS65T) reporter gene is introduced in combination with thenpt II selectable marker gene into axillary bud derived embryogenic calli of perennial ryegrass ( Lolium perenne L.) by co-cultivation withAgrobacterium tumefaciens strain AGL0 harboring binary vector pYF132.

Observation of the phenomenon of plant light cycle
Time of Update: 2021-03-13
Under the condition of natural light, plants are artificially given short daylight, intermittent day, intermittent night and so on to understand the alternating day and night light and darkness and its length on the strong flowering of her ears, soybeans, rice and other short-day crops.

Nelumbo nucifera
Time of Update: 2021-03-13
Plant height 1 to 2 meters, root-shaped stem fat, horizontal underground, outer skin yellow-white, sectional scaly leaves and indeterminite roots, between the section puffed, spindle-shaped or column-shaped, with honeycomb-shaped holes.
After the flower thanks, the flower topple into a lotus pontoon, endo-made most nuts (commonly known as lotus seeds).

Grape rooting
Time of Update: 2021-03-13
The reason is that grape bud eye germination requires a lower temperature, generally at about 10 degrees C can germinate.
Rooting requires a high temperature, and rooting at 25-28 degrees C is the fastest.
