Cellular processes in twining plants and tendrils
Šimečková, Jana ; Krtková, Jana (advisor) ; Skokan, Roman (referee)
This work focuses on the twining of stems and tendrils of vines and the underlying cellular processes involved. Vines, comprising a diverse group, require support for their growth and are known as "climbers." Successful coiling depends on the contact between the plant and the support, this contact is facilitated by movements such as skototropism and circumnutation. Once in contact with the support, coiling occurs. Specialized G-fiber cells appear to play a crucial role in the coiling process. Additionally, microtubules and cellulose microfibrils are extensively studied in the context of helical growth. Although the complete picture of cellular signaling during coiling remains elusive, numerous chemical substances influencing coiling have been identified, including jasmonates and other plant hormones. Many significant plants fall into the category of climbing plants, yet much remains unknown about their coiling mechanisms.
