 \section*{Introduction}
 \begin{longenum}
-    \item To avoid the process of plant material sterilisation, sterile cultures of plants growing in \textit{in vitro} conditions are recommended as a source of explants.
-    \item When seedling fragments are used as explants, seeds can be sterilised.
-    \item Seeds can be germinated \textit{in vitro}, providing a sterile seedling culture.
-    \item When explants are taken from mature plant tissue, donor plants are typically not maintained in sterile culture.
-    \item In such cases, sterilisation is necessary.
-    \item An exception includes species from the \textit{Solanaceae} family (e.g., tomato, tobacco).
-    \item These plants are easily maintained in \textit{in vitro} culture through propagation by "cuttings."
-    \item These cuttings are grown on MS10 agar medium.
-    \item Plants from germinated \textit{in vitro} seeds of the \textit{Solanaceae} family can be propagated by cuttings.
+    \item Sterile \textit{in vitro} plant cultures are recommended as sources of explants to avoid repeated sterilization of plant material \cite{George2008}.
+    \item When seedling fragments are used as explants, seeds can be sterilized and germinated \textit{in vitro}, providing axenic seedling cultures.
+    \item For explants taken from mature plant tissues, donor plants are typically not maintained in sterile culture, necessitating surface sterilization of the explant material \cite{Cassells2012}.
+    \item An exception includes species from the \textit{Solanaceae} family (e.g., tomato, tobacco), which are easily maintained in \textit{in vitro} cultures through propagation by cuttings.
+    \item These cuttings are grown on Murashige and Skoog (MS) medium \cite{Murashige1962}, commonly supplemented with 1\% sucrose (MS10).
+    \item Plants from germinated \textit{in vitro} seeds of the \textit{Solanaceae} family can be propagated by cuttings, providing a continuous source of sterile explant material.
