The field investigation led by Professor Xie Gaoyi did not gain more after the surprise created by Yang Rui. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

It is also natural that the discovery of new species is not difficult to say, but simple is not simple.

If you organize a survey of Shennongjia species, or the distribution of seabed organisms, it is natural to find dozens of new species, but in the main teaching area of hundreds of colleges and universities in Beijing, in the Badaling forest area, if you want to find a new species, it will have to be pure luck.

Or goldfinger.

Yang Rui undoubtedly took the results of his descendants, but from an academic point of view, this did not have any impact.

This new plant of the genus Blue Thorn was originally discovered during a field screening in the Badaling forest area. The so-called screening is naturally not as simple as field investigation, and it is a little too much to describe it as a dragnet inspection, but from the perspective of wild biology, its scale is almost the same meaning, nothing more than the size of the mesh.

This kind of field screening will collect a lot of plant specimens, and whether new species can be found depends more on the analysis and identification of standards by scholars.

As Professor Xie said, there are thousands of specimens waiting to be examined at Peking University alone, and if scholars have enough time, it is possible to find dozens of new species, or even hundreds of new species.

However, there are many biology enthusiasts, but there are only a handful of taxonomists who are really capable of identification.

However, Yang Rui's newly discovered blue thorn head is a new plant, which can naturally be identified by Professor Xie's priority. Not only did Yang Rui want to know the results, but the other 24 students in the same group also wanted to know if there would be a new species.

The discovery of new species or something, although it is a very common thing in the academic world, but in the eyes of laymen, it seems to be a very important thing, after all, ordinary people do not understand the significance of the function of ion channels, but ordinary people often regard the discovery of species as very important, as if the discovery of a new species makes a big step forward in the level of human biological science.

For the students, if Yang Rui can discover a new species, everyone will at least get a new talking point. Seeing that the Chinese New Year is coming, this time when I go home, I can tell the seven aunts and eight aunts about my college life.

Otherwise, every time you go back, you will say that you have learned to do electrophoresis, and everyone will not take it seriously -- swimming in electricity is nothing more than a matter of guts, and there are still few bold and reckless offspring in the village? Perhaps, this classmate will be warned by the village chief: You are the only college student in the whole village, and you can't give up your life for the sake of practicing courage.

All in all, the students came to the ion channel lab with curiosity.

Not only the students who went to participate in the field investigation, but also many students in the Department of Biology who received the news, there are many people who are curious about this strain, which may be the first new species discovered by the students of the Department of Biology of Peking University.

The reason for the identification in the ion channel laboratory is also very simple, Yang Rui decided to use PCR to identify the source for the first time.

PCR technology has been invented by Yang Rui for two years.

The use of PCR in taxonomy is a natural idea - PCR is the technique of replicating and comparing DNA, DNA is the genetic material of organisms, and taxonomy seeks homologous organisms...... Therefore, experts in taxonomy began to apply PCR technology more than a year ago.

However, for the Chinese academic community in the 80s, two years is so short, not to mention popularization, the attempt is just beginning, the domestic PCR instrument is simple, but the reagent is not cheap, the most important thing is that most scholars are still in the state of learning imported knowledge in the past few years, just like high school students do not care about the changes in college textbooks, the overall change in the domestic biology community is still slow.

As a professor in the Department of Botany of Peking University, Professor Xie also wanted to start learning PCR from scratch with his relationship with Yang Rui.

Therefore, after a small amount of communication, Professor Xie directly brought the specimen to Yang Rui's laboratory.

The students swarmed in.

……

Xu Anqing looked at the ceiling of the ion channel laboratory with fascination.

The renovated ion channel laboratory has a clean and bright floor, and the ceiling is also made of composite materials, which is very different from the usual gray roofs or painted white roofs today.

Of course, such a level of decoration is not unusual, and Xu Anqing doesn't know how many places he has been to.

However, thinking that this was Yang Rui's territory, and Yang Rui was the person in charge of this laboratory, Xu Anqing felt full of strangeness.

"I was also the second place in the national college entrance examination that year. Xu Anqing remembered the past inexplicably. To say, the junior Xu Anqing, has not recalled the college entrance examination Yunyun for a while, his college career is very smooth, of course, it is not comparable to Yang Rui, but it is also very smooth, he has also published papers in academic journals, although it is a Chinese journal, but still, this is an achievement that only a few people in Peking University can achieve. In addition, Xu Anqing is also the winner of the school and even the national scholarship, and his academic performance has long been maintained before the 5% of his grade, in the grade of less than 100 students, which means that he is always in the top five of his grade.

Unlike 30 years later, the student results of the 80s are very valuable. First of all, from the most utilitarian point of view, academic performance can determine the distribution of graduation, and it has a very large weight. Under the national allocation policy, it is not easy for any unit to assign college students, and it is necessary to compete and compete, and when they finally get the allocation right, they naturally hope to get good students.

For more popular positions, such as the government agencies above the ministerial level in Beijing, if they are recruited in ordinary key schools, they basically only need top students, while at Peking University, students who rank 20% in academic performance can successfully go abroad with the results of top students and get full scholarships from developed countries.

As far as the environment of the 80s is concerned, no matter which one it is, it will completely change your life, and in the next forty or fifty years, you will live a life completely different from that of students with ordinary grades - basically any way, you can basically do it, no stealing, no robbing, no corruption, five houses before retirement.

In addition to his academic performance, Xu Anqing's social activities are also going very smoothly, although his family background inevitably helps, but he can join the party in his junior year, and smoothly enter the student union, and then become the minister of the logistics department of the student union, Xu Anqing has also done a lot of work, as a member of the Peking University Student Union, he also got the qualification to participate in the National College Student Federation this year, as far as the student organization is concerned, he is almost at the top.

However, all these achievements, which occasionally make Xu Anqing a little proud, were overwhelmed by a colorless ceiling.

The ion channel laboratory, which has been established for more than two years, is showing its style with brilliant momentum.

X-ray bio-style diffractometer, flow cytometer, environmental scanning electron microscope, isotope ratio mass spectrometer, two-dimensional electrophoresis system, ultracentrifuge, ion chromatograph, ......

You don't need to know the instruments themselves, just looking at their form is enough to determine.

The design of the first-class laboratory imitated that of later generations, and the ion channel laboratory of today behaves like a scene from a science fiction movie...... In fact, students in the 80s didn't have the opportunity to watch any science fiction movies, science fiction did exist, but no matter how they imagined it, I am afraid they could not imagine how magnificent a laboratory that cost 4 million US dollars and 6 million yuan to build is.

"Professor Xie, the electron microscope is here. Yang Rui gave Professor Xie and the accompanying students a brief introduction to the laboratory, and pulled everyone to the experimental area.

The experimental area was a little crowded, but fortunately it was quiet, and in such an environment, everyone naturally became light and talked in a low voice.

Xie Gaoyi nodded, came to the scanning electron microscope, looked at it for a while, and said a little embarrassed: "This is the electron microscope of Shimadzu i400, I haven't used it yet." ”

"Let Zhang Xuetong help operate. Yang Rui called Zhang Xuetong over as he spoke, and then began the formal species identification work.

Before the invention of PCR, that is, before DNA identification was possible, microscopic identification was the most commonly used method for speciation identification.

Although most species are so similar at the macro level that it is difficult for ordinary people to distinguish them, at the micro level, the gap in microstructure is huge, and no special training is required to distinguish them.

Xie Gaoyi began to observe with high spirits, and while observing, he hand-painted the image, which was outrageous.

It doesn't take him too long to draw the new plant form, and anyone with a discerning eye can see the similarities and differences between the stems and leaves.

"Yang Rui, I think you can start thinking about it and name it. Xie Gaoyi was in a good mood and gave Yang Rui a reassurance.

The discussion couldn't help but get louder.

Even Bai Ling looked at Yang Rui in surprise.

This luck is too good.

Yang Rui asked as if unconsciously: "What are the requirements for naming it?"

"Now it's all in the binomial method, the official name is Latin, it's okay, I'll translate it for you when the time comes. Let's start with the Chinese name. It is of the genus Blue Thorn, this cannot be changed, you can give a name to modify it, it can be a morphology, it can be a place name, it can also be a person's name......" When Professor Xie said the name of the person, the surrounding students were excited, this is their own name for the ages, although few people really care about the name of the plant or anything, but what if it can be used in medicine.

Think about it, ten grams of ginseng with three coins of angelica and two plants of Yang Rui's blue thorn head as a medicine primer to drink, any cold has to be cured.

"Zhang Fei's blue thorn. Yang Rui's voice interrupted everyone's assumptions.

Professor Xie asked as if he didn't hear clearly, "Who are you going to commemorate?"

If it's not your name, it's usually in honor of someone.

Yang Rui shrugged his shoulders and said, "I modified it according to the form, and the circle of bristles around its stems and leaves is very similar to the feeling of Zhang Fei's beard. ”

Professor Xie was not good, and said busily: "Don't be in a hurry to name it, don't be so hasty." ”

"Not hasty, I thought about it a long time ago, so I will use this name. In Yang Rui's mind, a multiple-choice question has already emerged, the following four, which one is not named after a person: Zhang Fei's blue thorn, Obama's lizard, Quack fern, and Bush beetle.

Yang Rui even thought of a reference answer: The distractor of this question is the Bush beetle, in English, Bush means shrub, students who choose this item, please do not write English homework in biology class!
