Plant Hormones & Other Growth Regulators

Welcome to the International Conference “Plant Hormones & Other Growth Regulators”!

Plant growth regulators (also called plant hormones) are numerous chemical substances that profoundly influence the growth and differentiation of plant cells, tissues and organs. Plant growth regulators function as chemical messengers for intercellular communication . There are currently five recognized groups of plant hormones: auxins, gibberellins, cytokinins, abscisic acid (ABA) and ethylene. They work together coordinating the growth and development of cells. Ethylene is mainly involved in abscission and flower secscence in plants and is rarely used in plant tissue culture. In addition to the five principal growth regulators, two other groups sometimes appear to be active in regulating plant growth, the brassinosteroids and polyamines.

As agriculture becomes more mechanized and science increases the possibilities for using inputs to enhance production, the role of PGRs becomes more vital.

Through discussions of the “classical five” phytohormones–gibberellins, cytokinins, ethylene, abscisic acid, and auxins–and the growing number of nontraditional PGRs such as oligosaccharins and brassinosteroids, the International conference “Plant Hormones and Other Growth Regulators” discuss the past and present uses of PGRs in managing crop yield and offers some speculation on future directions.

Vienna is located in the heart of Europe on the banks of the Danube River, and considered as one of the most important economic, cultural and touristic large cities of central Europe. Apart from providing top science, the Conference will capture the spirit of the city thanks to the central location of the venue offering a multitude of cultural events.

This two-days event will provide leading academy and industry scientists a platform to communicate recent advances in “Plant Hormones & Other Growth Regulators”, and an opportunity to establish multilateral collaboration.

The International Conference “Plant Hormones & Other Growth Regulators” will cover the following research topics:

  • Hormone Metabolism and Transport
  • Hormone Perception & Signaling
  • Hormone Biosynthesis & Metabolism
  • Hormone Interactions
  • Hormone Imaging
  • Hormone Evolution
  • Hormones & Development

Among the invited speakers are internationally known names such as:

Zhiyong Wang (USA), Ana Caño Delgado (Spain), Ana Margarida Fortes (Portugal), Chuanyou Li (China), Jerry Cohen (USA), Salim Albabili (Saudi Arabia), Alicja Banasiak (Poland), Dominique Van Der Straeten (Belgium), Maria Samsonova (Russia), Klaus Palme (Germany), Carolin Delker (Germany), Minsung Kim (United Kingdom),…

Approximately 250 participants are expected to attend this exciting scientific forum including almost 40 lectures delivered by worldwide known invited speakers and young, talented speakers selected from submitted abstracts. The program combines plenary lectures, poster sessions, a unique Conference Dinner Party and sightseeing tours of Vienna.

We are looking forward to seeing you in Vienna on February 17-18, 2020!

Deadline for submission of abstracts is January 20, 2020
