How to store texture and color of gameobject

i used the unity serializer to save the game and load it..but having a problem when i save and load it from button click on main menu.the texture i used on dynamic objects get null(that means it doesnot load texture and colors)and if i click again on new game to open a fresh game then also texture does not appear on the object.i search alot about this didn't find any solution.please tell me what should i do to get it..here is the snippet i used to resume the game.

 if(GUI.Button(new Rect(180,130,140,20), "Resume Game", mystyle)) {
             New =false;
             Load = true;
 
             if (!LevelSerializer.IsDeserializing)
             {
                 LevelSerializer.Resume ();
                 
             }
 if (GUI.Button (new Rect (10, 70, 70, 20), "Yes ")) 
         {    
             
             LevelSerializer.Checkpoint();
             //PlayerPrefs.SetInt("level01", Application.loadedLevel); 
             Application.LoadLevel("level02");
         }
