Adventitious shoot regeneration from stem internode explants of Verbena officinalis L., a medicinal plant

Öz:
Verbena officinalis L. (mine çiçeği) tıbbi bir bitki olup, anti-mikrobiyel, anti-inflamatuar, analjezik, nöroprotektif, hipnotik/sedatif, gastroprotektif, hepatoprotektif, anti-kanser, sikatrizan ve antioksidant gibi çeşitli biyolojik aktiviteler göstermektedir. Gövde internodal ve petiyol eksplantlarından adventif sürgün gelişimi yoluyla başarılı bir bitki rejenerasyon sistemi, bu türde ilk defa bu çalışmayla ortaya konulmaktadır. Eksplant başına sürgün sayısı ve sürgün oluşturan eksplantların yüzdesi bakımından, gövde internodal eksplantları petiyol eksplantlarından daha fazla etkili olmuştur. 13,32 μM’a kadar artan benziladenin (BA) konsantrasyonu sürgün oluşumunu düzenli olarak artırırken 22,22 μM BA ani bir düşüşe sebep olmuştur. En yüksek sürgün verimi (eksplant başına ortalama 17,1 sürgün ve eksplantların % 100’nün sürgün verdiği), 13,32 μM BA ile 5,71 μM indol-3-asetik asit (IAA)’nın kombinasyonunda elde edilmiştir. Çoklu sürgünler tek tek ayrılarak çeşitli konsantrasyonlarda farklı oksin içeren ortamlarda [IAA, indole-3-butirik asit (IBA), 2,4-diklorofenoksi asetik asit (2,4-D), veya naftalen asetik asit (NAA)] kültüre alındığında, rejenere olmuş sürgünler kolaylıkla köklendirilmiştir. Gelişen kök sayısı bakımından, 4,92 μM IBA, sürgün başına ortalama 7,1 kök üreterek daha etkili olurken, kök oluşturan sürgünlerin yüzdesi bakımından ise 5,71 μM IAA % 100 sürgün köklenme oranıyla daha başarılı olmuştur. Oluşan rejenerantlar saksılara aktarıldıklarında, % 90’dan fazlası alıştırma sürecini başarıyla tamamlamış ve düşük nemli bir ortama aktarılmadan önce iki hafta süreyle büyüme odası koşullarında tutulmuştur. Oda şartlarına aktarıldıktan yaklaşık üç ay sonra rejenere olmuş bitkilerin çiçeklendiği gözlenmiştir.

Tıbbi bir bitki olan Verbena officinalis L.’in gövde internodal eksplantlarından adventif sürgün rejenerasyonu

Öz:
Verbena officinalis L. (vervain) is a medicinal plant that shows several biological activities, including antimicrobial, antiinflammatory, analgesic, neuroprotective, hypnotic/sedative, gastroprotective, hepatoprotective, anticancer, cicatrizant, and antioxidant. This report describes an efficient plant regeneration system for V. officinalis via adventitious shoot development from stem internode and petiole explants. Stem internode explants were more effective than petiole explants in terms of both the number of shoots per explant and the percentages of explants forming shoots. Increasing benzyladenine (BA) concentrations steadily increased shoot formation up to 13.32 μM, but 22.22 μM BA caused a sharp decrease. The highest number of shoots (17.1 shoots per explant at 100% frequency) was obtained when 13.32 μM BA was combined with 5.71 μM indole-3-acetic acid (IAA). Rooting of the regenerated shoots was readily achieved when multiple shoots were singled out and cultured on medium containing varying concentrations of different auxins [IAA, indole-3-butyric acid (IBA), 2,4-dichlorophenoxyacetic acid (2,4-D), or naphthalene acetic acid (NAA)]. IBA was more effective in terms of the number of roots developed, producing a mean of 7.1 roots per shoot at 4.92 μM, whereas IAA was more effective for the frequency of shoots developing roots: 100% of the shoots rooted at 5.71 μM IAA. More than 90% of the regenerants survived through the hardening off process, when they were transferred to foam cups and kept under growth room conditions for 2 weeks before finally being moved to room conditions at low humidity. Approximately 3 months after the transfer to room conditions, the flowering of the regenerated plants could be observed.
