This is a topic that has not been systematically and clearly resolved for a long time in the scientific community. Based on genomic and genetic analysis, a research team led by the Kunming Institute of Botany, Chinese Academy of Sciences, proposed a new hypothesis of the function of “spur water storage”, which filled the gaps in the early functional research of skin thorns. Related research results were published online in the comprehensive journal National Science Review with the title “A genomic link in China roses: and they all lived prickly but water deficient ever after?”. Prickles refer to sharp protrusions formed on the epidermis or cortex of plants. They are usually considered to be the defensive adaptive tissues of plants to protect plants from animals, pathogens or mechanical damage. The “thorny rose” reminds people that although a rose is beautiful, beware of its thorns. Many plants such as Rosaceae, Leguminosae and Rutaceae have prickles on their stems, leaves and fruits, but the function of prickles in the early developmental stage has not been revealed yet. The genetic mechanism and ecological significance of prickles development of the rose genus of Rosaceae native to China have not been systematically and clearly analyzed for a long time. The picture shows the research results.Photo courtesy of Kunming Institute of Botany, Chinese Academy of Sciences Recently, the plant molecular genetics and adaptation research team of the Kunming Institute of Botany, Chinese Academy of Sciences has cooperated with the Southwest China Wildlife Germplasm Bank and the Yunnan Academy of Agricultural Sciences team to use the ancient Chinese rose thornless leaf rose (Rosa wichuraiana Basye’s Thornless, BT) and Moon powder (R. chinensis Old Blush, OB) and its hybrid F1 and backcross BC1F1 generation genetic populations are used as test materials. Comprehensive use of comparative genomics, molecular genetics and evolutionary biology methods to analyze the genetics of rose thorns Regulation mechanism. The research team first used scanning electron microscopy to compare the early development of BT and OB prickles and found that the lack of BT prickles may be an abnormality in the initial ability of prickly development. After two consecutive years of phenotypic analysis based on the F1 and BC1F1 generation populations of BT x OB, it was found that the heredity of rose thorn density was incompletely dominantly controlled by four genetic loci, and finally two loci were mapped. In order to gain a deeper understanding of the genetic regulation mechanism of rose thorn development, the team constructed a high-quality reference genome at the diploid BT chromosome level, conducted a comparative genomic analysis of BT and OB, and found that the thorn density may be related to water adaptation. To further explore this hypothesis, the team also conducted a series of physiological tests on 41 genotypes of rose. Compared with the epidermis and leaves, the prickles of the old branches can be more water-enriched, and the degree of enrichment is higher in the young prickles; the moisture content of the prickles in the older branches is significantly reduced; this phenomenon is not only It appears in modern cultivated lines and ancient Chinese rose germplasm, and it is also consistent in wild roses and other materials. Based on this, the research team puts forward the hypothesis that the young skin spines are likely to have a water storage function. “Although this hypothesis requires more genetic evidence, it completes the chain of research on the biological functions of prickles: that is, young prickles are mainly used for water storage, while mature prickles are mainly used for defense and water loss. “Scientists said that this research not only promotes the analysis of the genetic mechanism of rose thorn development, but also facilitates the development of rose biology and the cultivation of new germplasm, but also provides a new understanding of the production and maintenance mechanisms of new plant traits.

The statement states that the decision made by the Polish Foreign Ministry was due to the fact that three Russian diplomats have engaged in activities that are inconsistent with diplomatic regulations and endanger Poland’s security.

The statement also expressed Poland’s absolute support for the US measures taken against Russia on April 15.

It is known that earlier in a related development, the US government announced to impose large-scale sanctions on Russia. At the same time expelled 10 Russian diplomats, on the grounds of conducting cyber attacks and interfering in the US presidential election.

The British Foreign Ministry has summoned the Russian Ambassador regarding London’s deep concern about Russia’s hostile policy.

According to Russian media, the British Foreign Ministry has summoned Russian Ambassador to London Andrei Kelin, regarding Russia’s “hostile line of conduct”, the London Foreign Service said in a statement.

Meanwhile, Russian Ambassador to Warsaw, Sergei Andreev, was summoned to the Ministry of Foreign Affairs of Poland. According to diplomatic sources, the reason for the summons was related to “the introduction of new sanctions by the United States against Russia”. Another reason may be the situation on Ukraine’s eastern border.

Two weeks later, more than 40 Chinese ships remained in the Ba Dau Stone and the statements became more concise. The Philippine Foreign Ministry on April 12 warned China that Manila would issue daily protest diplomatic notes as long as the mainland’s “marine militia” remained in the area. The Philippines authorities have used a phrase similar to the US way of describing the Chinese fleet.

Bloomberg quoted Carl Schuster, former director of missions at the US Pacific Command’s Joint Intelligence Center as commenting: “If your goal is to capture an ocean and atoll, without fighting, this is an excellent dishonesty tactic. Only professional seafarers knew it was a lie. No one allowed their ships to ‘shelter’ in the hurricane zone several weeks before a storm. If they were really commercial ships, it would cost hundreds, if not thousands, of dollars a day to lay these ships idle side by side.

Analysts Andreo Calonzo and Philip Heijmans said Beijing appears to be probing whether the new US President Joe Biden will take any action after pledging to shake hands with allies in the region to prevent Chinese assertiveness or not. Philippine Foreign Minister Teodoro Locsin blamed the Obama administration for failing to stop Beijing in a similar incident in 2012 at Scarborough Shoal.

“This is a test of what the Biden administration is willing to do. The way the US responds will determine the next challenge. For now, everything we (the US) have done is more eloquent than substantive, ”said Schuster, currently professor in military science and diplomacy at the University of Hawaii Pacific. emphasize.

Complex decisions

Last month, the US vowed to stand with the Philippines while accusing China of using “maritime militias to intimidate, provoke and intimidate other countries”. When asked about relations with China at a news conference the same month, President Biden revealed that his administration “would hold China accountable for obeying the rules” in the South China Sea and elsewhere.

Another big problem is how to correct the response. China’s use of commercial fishing vessels resembles a “gray zone” tactic, allowing Beijing to deny that anything is wrong. Sending an aircraft carrier or other warships near the reef risks becoming an overreact, making the United States seem like the aggressor.

On the contrary, doing nothing can give the impression of weakness. Over the past few years, the United States has increased its challenge of China’s sovereignty over the waters, increasing the frequency of free navigation operations around disputed territories. The Biden administration also reaffirmed that the US-Philippines defense treaty covers every attack in the South China Sea, which was made clear under former President Donald Trump after decades of ambiguity.

Another major problem for Mr. Biden is Philippine leader Rodrigo Duterte, who has weakened the alliance while praising closer ties with Beijing.

According to Rommel Ong, a retired Philippine Navy admiral and now professor at the Ateneo de Manila University School of Management, under President Duterte there will be only very limited options for the Navy. Manila’s response is believed to be limited to sending objectionable diplomatic notes and anti-China statements via social media.

The Philippines’ statement on April 12 used some of the strongest words, including a 2016 international arbitral tribunal ruling. The statement also condemns the Chinese Embassy for criticizing the minister. Defense Delfin Lorenzana, who last weekend said the weather was fine and boats had no reason to stay in the Ba Dau Rock area.

Warning

Duterte’s government responded to China’s April 3 statement with a statement that it hopes Filipino officials will “avoid any unprofessional remarks that may add to irrational feelings”. . On April 13, Chinese Foreign Ministry spokesman Zhao Lap Kien accused the Philippines of violating the United Nations Charter, the Law of the Sea and international law by invoking the 2016 ruling of the United Nations court. But Beijing insisted on rejecting.

Mr. Trieu warned the Philippines should see the situation “objectively and properly, stop exaggerating the problem to avoid any negative effects on the bilateral relationship between the two countries, stability and peace in the country. East Sea”. The Beijing representative also denied that the Chinese ships illegally present in the Ba Dau Rock belonged to the maritime militia.

President Duterte broke his weeks-long silence with an April 13 statement, insisting the dispute would be resolved through “peaceful measures” and would not “shape the relationship. Bilateral”.

“It will not be an obstacle to the positive overall development trajectory of our bilateral friendship,” the Philippine government leader said in the statement, citing increasingly deep cooperation. vaccine against Covid-19 and “economic recovery from the pandemic” between the two sides.

Reputation is compromised

Vaccine access has become a major concern for Mr. Duterte. Manila was shut down again last week as the Philippines faces its worst outbreak and is expecting much of the vaccine supply from Chinese pharmaceutical company Sinovac.

The Philippine President attended a March 29 celebration in which Chinese Ambassador Huang Zilian said the vaccine was a testament to the “closer cooperation in the new era” between the two countries.

Shahriman Lockman, a senior analyst at the Institute for Strategic and International Studies in Malaysia, said that this time, Washington was “not so naive” after a failed attempt in 2012 to reach a withdrawal agreement. retreating from Scarborough Shoal “did great damage to American prestige in Southeast Asia”. According to Mr. Lockman, the Biden administration is wary of the danger of sinking into this scenario and not knowing if they will eventually be blamed for escalating the situation, which is quite possible while the Philippines capable of reacting only in a perfunctory way.
