The researchers demonstrated how a group of hormones affects the growth of Vda plant roots

Prague / Olomouc The effect of the brassinosteroid hormone on plant root growth was demonstrated by the Belgian biologist ESKTM. Research findings that influence levels of these hormones affect cell length and growth contribute to a better understanding of the root system. In the future, for example, it could help increase crop resistance. Vd R Academy (AV) reported research in journalism first. The study has been published in Nature Plants.

Plant hormones are essential for the proper growth and development of plants. They develop in this way in the propagation and cultivation of agricultural crops and ornamental flowers. The first group of plant hormones, called brassinosteroids, greatly affect, for example, the growth of roots.

Prazinosteroids have a complex effect on plant growth and development. The aim of this project was to clarify its role in root growth. We participated in both biological experiments in Ghent, Belgium, where Petra Girotov, a PhD student, was a long-term student, as well as Jan Oklikov, who was behind the quantification of brassinosteroids in hundreds of individual roots. The team examined in detail the effect of brassinosteroids on the roots of a field beetle experimental plant.

There is tissue on the rootstock – an area in which beech is more intensively divided. Behind the meristem, there is an extension, in which beech trees grow simultaneously, but grow sharply in height. Brasinosteroids control both processes. Molecules of these hormones bind in every process of beech wood, weakening and enhancing the activity of the tisc gene. At the root, the expanded beech wood tends to respond more strongly to these hormones. So far, according to vdc, the bag is unclear, which is why it is. The possibility was either the level of brassinosteroid in this portion of the root or the intolerance of the cells to the plant hormone. The group fell in love with the answer.

Glue plant resistance

Experts have shown that low concentrations of brassinosteroids support the length of the root cells, and high concentrations stimulate the lengthening of these cells. Hence, changes in hormone levels along the rootstock are likely to be information about whether to buy or grow in height.

We know that the results will help clarify the complex issues of the synthesis and transport of these hormones in plants. Oklikov concluded that this could be used in agriculture, for example, to increase the resistance of crops to various stressors, such as lack of water in the soil.

The research group consists of scientists from the Laboratory of Growth Regulators in Olomouc, working together on the state of experimental botany of the Academy of Sciences and Palacky University in Olomouc, and experts from Ghent University and the Center for Systemic Plant Biology VIB and Mata Fendrych from Prodovdeck College at Charles University in Prague.
