Scientists are using genetic engineering to make trees produce more terpenes. Is it possible to genetically engineer trees to produce more hygroscopic volatile organic compounds? These trees could be used in drought areas to create more rain.

    $\begingroup$ Welcome to Biology.SE! Don't forget to take the tour. Could you add a source for your terpenes claim? It would also help to give examples of hygroscopic volative organic compounds, although it's not essential. $\endgroup$ – arboviral Sep 9 '16 at 7:45

    $\begingroup$ I can't recall any hygroscopic volatile compound. Hygroscopic molecules carry-out electrostatic attraction (polar or ionic whatever) with each-other, so they are in most cases not volatile. $\endgroup$ – Always Confused Sep 9 '16 at 12:15
  • $\begingroup$ Your question is just too broad (also opinion based). Please add details and avoid asking open ended questions. $\endgroup$ – WYSIWYG Sep 9 '16 at 12:38
  • $\begingroup$ I think it is 2 question : 1. could we genetically engineer trees to produce any compound? (that is a broad question) and 2. hygroscopic materials sometimes used to produce artificial rainfall, so is there any volatile (organic-volatile preferable) compound that is also hygroscopic? (which is a pure chemistry question). $\endgroup$ – Always Confused Sep 10 '16 at 14:31
  • $\begingroup$ probably this question is inspired from any such artificial rainfall article like en.wikipedia.org/wiki/Cloud_seeding#Methodology $\endgroup$ – Always Confused Sep 10 '16 at 14:32
