Un gruppo di scienziati australiani sta lavorando sulla creazione di un cotone che cresce già colorato: si tratta di modifiche genetiche, già testate con successo su alcune piantine di tabacco, cresciute con macchie di diversi colori sulle loro foglie.
Queste modifiche al genoma della pianta, naturalmente di un bianco candido, porterebbe non solo a un grande risparmio economico, ma anche a ridurre l’impatto ecologico delle colorazioni tessili attualmente usate, che vengono spesso effettuate con prodotti potenzialmente tossici e dannosi per l’ambiente.
Ci vorranno ancora alcuni mesi per vedere i risultati, ma le premesse per un cotone più… verde ci sono tutte.
