    pollen typhae

    Echemi shares different kinds of information about pollen typhae. Maybe you'll get different insights into pollen typhae here.
    • Scientists reveal the molecular mechanism of pollen-stigma recognition

      Time of Update: 2021-04-17
      with active oxygen inhibitors and scavengers Later, it was found that the reduced stigma active oxygen level promoted pollen hydration. Treatment of wild-type stigmas with PCP-B small peptides from pollen coverings can cause
    • Why are more and more people allergic to pollen

      Time of Update: 2021-04-17
      The high pollen concentration and the high incidence of willow catkins have caused many people to lose out in the fight against various allergic symptoms.
    • Milestone progress in allergic diseases, the world's first Artemisia pollen sublingual immunotherapy drug was launched

      Time of Update: 2021-04-13
      >. The latest research data shows that long-term desensitization treatment can effectively prevent re-allergies in the pollen season
    • Researchers use environmental DNA to detect grass pollen levels

      Time of Update: 2021-03-19
      " Rowney said, "Because different types of grass pollen particles are usually not They are distinguished by light microscopy, so most epidemiological investigations focus on people exposed to total grass pollen concentrations and their relationship with allergy-related health outcomes.
    • Scientists have discovered a new method of quantitative testing of mixed pollen ingredients

      Time of Update: 2021-03-16
      the new hybrid pollen quantitative analysis, known as "genome scanning", required only pollen from a bee's pollen basket to perform genome screening, the researchers said.
    • Pollen grain germination

      Time of Update: 2021-03-15
      For example, rice, sugar cane, sorghum, etc., sprouted almost immediately after pollination; enzymes stored in pollen grains and various metabolic substances are important factors in pollen germination.
    • Modulating and Monitoring MAPK Activity During Programmed Cell Death in Pollen

      Time of Update: 2021-03-14
      MAPK inhibitors provide a useful tool to dissect these mechanisms and distinguish their regulation by different signaling pathways.

      Time of Update: 2021-03-14
      Here we describe the development of a lab-on-a-chip (LOC) for the manipulation and experimental testing of individual pollen tubes.
    • Pollen tube

      Time of Update: 2021-03-13
      The cytoste behind the cap area contains a variety of cytocytes, which are associated with the growth of pollen tubes.
    • Cell Biological Analyses of Anther Morphogenesis and Pollen Viability in Arabidopsis and Rice

      Time of Update: 2021-03-12
      approaches. In this chapter, we summarize the widely used protocols for pollen viability staining; the investigation of anther morphogenesis by light microscopy of semi-thin sections; TUNEL assay for programmed tapetum cell death; and laser microdissection procedures to obtain specialized cells or cell layers for carrying out transcriptomics.
    • The life of pollen (pollen viability)

      Time of Update: 2021-03-12
      Pollen preservation requirements of the plant, such as rice at 12 degrees C, 85% of the relative humidity conditions, the living force can be maintained for 24 hours.
    • The main culprit for pollen sensitivity is not "flowers" but "trees".

      Time of Update: 2021-03-07
      addition, leading to allergy symptoms, in addition to relying on the "wind media" spread of tree pollen, there are wrapped in tree seeds flying.
    • The scientists' new findings provide an explanation for the phenomenon of "same pollen first"

      Time of Update: 2021-02-22
      Interestingly, however, whether it is the small peptide signal AtLURE1 or the receptor that feels the signal, the plant is able to successfully complete the pollen tube attraction and subsequent fertilization process after loss of function, and produce normal seeds.
    • Is bee pollen an all-powerful food?

      Time of Update: 2021-02-06
      , regulating the gastrointestinal" "liver protection" and so on. Because it can cause a person's allergy, there are no reports of side effects, so manufacturers casually nonsense will not cause serious consequences. However, consumers need to be clear that these features are not "scientifically researched", as advertised, but are essentially "decided" by advertisers themselves.
    • Pollen Electrotransformation in Tobacco

      Time of Update: 2021-01-19
      Numerous techniques have been developed to transfer genes into plants to create genetically engineered crops that can tolerate environmental stresses, and to improve productivity and quality. The search for easier, more efficient
    • Pollen Tube Development

      Time of Update: 2021-01-14
      Pollen tubes grow rapidly in a strictly polarized manner as they transport male reproductive cells through female flower tissues to bring about fertilization.
