Abstract

Plants are exposed to environmental stresses and their combinations throughout their lives. Photosynthesis, a basic physiological process in all plants, is severely affected by these stress factors. The effects of environmental stresses on photosynthesis are either direct effects such as limitation of CO2 by stomata and mesophyll and changes in photosynthetic metabolism or indirect effects such as oxidative stress. Phytohormones, on the other hand, are essential both for plant growth and development and play an important role in regulating responses to abiotic stress conditions. In this review, the role of photosynthesis and phytohormones in plants exposed to environmental stress conditions are discussed.

Özet

Bitkiler yaşamları boyunca çevresel streslere ve bunların kombinasyonlarına maruz kalmaktadırlar. Tüm bitkilerde temel fizyolojik bir süreç olan fotosentez, bu stres faktörlerinden ciddi bir şekilde etkilenmektedir. Çevresel streslerin fotosentez üzerindeki etkileri ya stoma ve mezofil yoluyla CO2’nin sınırlanması ve fotosentetik metabolizmada değişiklikler gibi doğrudan ya da oksidatif stres gibi dolaylı etkilerdir. Fitohormonlar ise hem bitki büyüme ve gelişmesi için gerekli olup hem de abiyotik stres koşullarına karşı tepkilerin düzenlenmesinde önemli bir rol oynamaktadırlar. Bu derlemede, çevresel stres koşullarına maruz kalan bitkilerde fotosentez ve fitohormonların rolü ele alınmıştır.
