The expression of a tubby-like protein from Malus domestica ( Md TLP7) enhances abiotic stress tolerance in Arabidopsis

Background Tubby-like proteins (TLPs), characterized by a signature tubby domain, are widespread in plants and animals. To date, only plant TLPs involved in multifarious stress responses and male gametophyte development have been identified. However, studies on the molecular functions of plant TLPs are largely unknown.
