Abstract

As a consequence of global climate change, increasing carbon dioxide, temperature and drought factors and their interactions are affecting photosynthesis. In addition to different photosynthesis mechanisms such as C3 and C4 in plants, C4 plants have three subspecies: NAD-malic enzyme (NAD-ME), NADP-malic enzyme (NADP-ME) and PEP carboxylase. The NAD-ME plants had more water use efficiency under arid conditions than NADP-ME plants, NAD-ME C4 plants have better growth and photosynthesis activity under increasing CO2 conditions. C4 plants show less response to increased CO2 conditions than other plant species on the other hand, it uses water and nitrogen more effectively. For this reason, some C3 crops especially wheat and rice are undergoing breeding experiments to transfer the C4 pathway.

Özet

Küresel iklim de ğ i ş ikli ğ inin sonucu olarak artan karbondioksit, sıcaklık ve kuraklık faktörleri ve karşılıklı etkileşimleri fotosentezi etkilemektedir. Bitkilerde C3 ve C4 gibi farklı fotosentez mekanizmalarının yanı sıra C4 bitkilerinde NAD-malik enzim (NAD-ME), NADP-malik enzim (NADP-ME) ve PEP karboksilaz olmak üzere üç alt tür oldu ğ u g ö zlenmektedir. NAD-ME bitkilerinin kurak koşullar altında su kullanım etkinli ğ i, NADP-ME bitkilerine g ö re daha fazla olup, NAD-ME C4 bitkileri artan CO2 koşullarında daha iyi büyüme ve fotosentez etkinli ğ ine sahiptir. C4 bitkileri artan CO2 koşullarına, di ğ er bitki t ü rlerine göre daha az tepki göstermekte buna karşın suyu ve azotu daha etkin kullanmaktadır. Bu nedenle bu ğ day ve ç eltik ba ş ta olmak ü zere baz ı C3 bitkilerine C4 yolunun aktar ı lmas ı y ö n ü nde ı slah ç al ış malar ı devam etmektedir.
