Abstract

Elicitor and precursor applications are commonly used to induce secondary metabolism in plant cell cultures. In this study, methyl jasmonate, jasmonic acid, salicylic acid and pectin were used as elicitors and β-sitosterol was used as a precursor in batch cultures of Astragalus trojanus in order to trigger astragaloside IV and cycloastragenol productions. Growth parameters (fresh and dry weights and dry weight percentages) of batch cultures were also evaluated in order to understand the effects of elicitors and precursor on primary metabolism. All elicitors and precursor used in this study triggered metabolite production at different stages of culture period. The highest astragaloside IV accumulation (0.9435 µg/mg) was detected in medium supplemented with 50 µM methyl jasmonate at the 14th day of culture period, whereas the highest cycloastragenol concentration (0.3626 µg/mg) was found in medium supplemented with 50 µM jasmonic acid at the 28th day of culture period. Large scale cultivation was also performed and 0.3759 µg/mg astragaloside IV was detected in medium supplemented with 50 µM methyl jasmonate at the 14th day.

Özet

Elisitör ve prekürsör uygulamaları bitki hücre kültürlerinde sekonder metabolizmayı hızlandırmak için sıklıkla kullanılan uygulamalardır. Bu çalışmada Astragalus trojanus kesikli kültürlerinde astragalozit IV ve sikloastragenol üretimlerinin arttırılması için metil jasmonat, jasmonik asit, salisilik asit ve pektin elisitör olarak, β-sitosterol ise prekürsör olarak kullanılmıştır. Kesikli kültürlerin büyüme parametreleri (yaş ve kuru ağırlıklar ve kuru ağırlık yüzdeleri) elisitörler ve prekürsörün primer metabolizma üzerine etkilerinin belirlenmesi için değerlendirilmiştir. Elisitörler ve prekürsörün kültür periyodunun farklı basamaklarında metabolit üretimini tetiklediği belirlenmiştir. En yüksek astragalozit IV birikimi (0.9435 µg/mg) 50 µM metil jasmonat içeren besin ortamında kültürün 14. gününde görülürken, en yüksek sikloastragalozit konsantrasyonu 50 µM jasmonik asit içeren besin ortamnda kültürün 28. gününde tespit edilmiştir. Çalışmada büyük ölçekli kültivasyon da gerçekleştirilmiştir ve 50 µM metil jasmonat içeren besin ortamında 14. günde 0.3759 µg/mg astragalozit IV birikimi tespit edilmiştir.
