4. Validation for herbal medicine

Herbal RemediesHerbal medicine is still widely used around the world. In rural areas of some countries, such as Pakistan, herbal remedies can sometimes be the only treatments available.

  • A study done by local researchers focused on local gynecological herbal-based remedies has shown that some plants used for the treatment of different complaints, including menses disorders and honorrhea, can be useful from pharmacological points of view.
  • Local plants of Asteraceae and Amaranthaceae families were shown to be the most effective.
Reference: “Ethnopharmacology and toxicology of Pakistani medicinal plants used to treat gynecological complaints and sexually transmitted infections – ScienceDirect”. Accessed March 19, 2019. Link.

5. Plant extracts found to be effective Fungicides

Fusarium oxysporumCastor oil plants have several important uses in medicines. However, they have their own diseases, mainly wilt, caused by a fungal species, Fusarium oxysporum.

  • Previously, toxic fungicides were used as protection against this disease. However, the researchers have found an alternative-plant extract.
  • Such common plants as henna, neem cake, and aloe extracts were found to be highly effective at killing fungal cells.
  • Now the researchers plan to study these plants further, in order to develop better methods of protection against fungal infections.

7. Network of genes that controls petal senescence was discovered

Oncidium orchid leavesA team of scientists has attempted to describe the falling of petals in terms of genes instead of poetry.

  • They tracked the changes in the transcriptome of Oncidium orchid petals in the course of their development.
  • It was found that the shift to petal senescence was controlled by a complex gene network including genes responsible for circadian rhythms as well as some plant hormones genes, including gibberellin, brassinosteroid, and salicylic acid, as well as some signaling cascades.
Reference: “Transcriptome analysis of Oncidium petals provides new insights into the initiation of petal senescence” – Cui-Ping Yang, Zhi-Qiang Xia, Jin Hu, Yu-Fen Zhuang, Ying-Wen Pan & Jin-Ping Liu. Accessed March 19, 2019. Link.

8. Silicone as a plant protector

High plantsSilicone has not been previously considered an essential element for higher plants.

  • However, mounting evidence shows that plants do absorb this element. Moreover, modern transcriptomics has revealed the crucial importance of this element in stressful conditions.
  • Based on new research done in 2018, it was shown that though silicone does not alter gene expression in plants in a regular environment, its role changes when the plants are under biotic stress.
  • For instance, Si supplementation is necessary to counteract damage in plants growing in conditions with high salt content.

9. Metabolomics shows the unseen differences in a popular plant

Plant soilA unique study was carried out in Denmark. The researchers undertook a broad metabolic analysis of 15 different populations of broadleaf plantains, Plantago major, that came from different areas of the country.

  • This study has shown that the metabolomes of the plants significantly differed depending on the location, as soil pH, the presence of herbivores, light levels and other parameters all influenced the number of metabolites.
  • Potentially, many inferences about the plant growth conditions and even geographic location can be made based on the features of their metabolism.
Reference: “Untargeted metabolic profiling reveals geography as the strongest predictor of metabolic phenotypes of a cosmopolitan weed”. Accessed March 19, 2019. Link.

10. Novel Genetics-based approach to optimize crop production

CropsPhosphorus (P) is a crucial element for plants. In the case of P deficiency, root development and architecture can be heavily impaired.

  • That is why most crops are dependent on phosphorus fertilizers, but their overuse is dangerous.
  • It is now possible to identify genetic loci in plants that are responsible for efficient P absorption.
  • By monitoring and selecting for these loci, it is possible to improve overall yield in crops, as well as evade overuse of fertilizers.
Reference: “Utilization of molecular markers for improving the phosphorus efficiency in crop plants” – Theivanayagam Maharajan, Stanislaus Antony Ceasar, Thumadath Palayullaparambil Ajeesh krishna, Muthusamy Ramakrishnan, Veeramuthu Duraipandiyan, Al‐Dhabi Naif Abdulla, and Savarimuthu Ignacimuthu. Accessed March 19, 2019. Link.

11. Auxin triggers a specific pathway in palm oil plants

Palm-oil plantIn oil palm cultivation, the fruit developed without fertilization (parthenocarpic) is the most economically advantageous, as they contain the highest palm oil percentage.

  • It was found that auxin treatment before the opening of the flower stigmas could induce 100% development of parthenocarpic plants.
  • It was also found that auxin triggered a certain genetic pathway that eventually led to the development of parthenocarpic fruit.
  • The researchers hope that more research would lead to a better understanding of the parthenocarpic mode of development.
Reference: “Transcriptome analysis of oil palm inflorescences revealed candidate genes for an auxin signaling pathway involved in parthenocarpy [PeerJ]”. Accessed March 19, 2019. Link.

12. Tracing the evolutionary history of an amazing plant group

CaryophyllalesCaryophyllales is an order of higher plants that exhibit a fantastic variety of adaptations.

  • This group contains species with extreme heat tolerance (such as cacti), carnivorous plants (Venus flytrap) and even plants able to accumulate heavy metals.
  • The genome-wide transcriptomic analysis allowed the researchers to understand the relationships between such diverse species better and gain better insight into the evolution of such diverse adaptations.

15. Cognition in plants is real

Plant cognitionThe knowledgeable, intellectual trees of fantasy may be the objects of fiction.

  • Still, the mounting evidence suggests that plants actually have cognition quite similar to animals.
  • They can react and adapt to stimuli in the same basic way animals do, though the types of reactions are different.
  • These newly discovered cognition processes are at present are of highest interest to plant neurobiologists.
Reference: “Are plants cognitive? A reply to Adams” – Miguel, Segundo-Ortina, and Paco Calvo. Accessed March 19, 2019. Link.

As you can see, botany in 2018 was far from the stale science it is sometimes viewed.

We continue to be highly dependent on plants, as they provide us with food, medicine and even novel questions about life itself and our place in the world.
