Embryonic mouse submandibular epithelia initiate branching morphogenesis within two days when embedded in Matrigel and stimulated by members of the epidermal growth factor family. However, it is unknown whether the end buds further branch over longer culture periods, and whether saliva-producing cells differentiate there. In the present study, we cultivated three major (submandibular, sublingual and parotid) salivary epithelia from 13-day embryos for 14 days in mesenchyme-free cultures. All epithelia continued to grow and branch to form numerous acinus-like structures in medium supplemented with neuregulin 1, fibroblast growth factor 1, and insulintransferrin-sodium selenite...

To gain insights into the molecular basis of starch degradation in wheat seeds with respect to dormancy maintenance and release, this study compared the expression of starch degrading genes between dormant and after-ripened seeds in both dry and imbibed states. Furthermore, the study examined the effect of ABA on the expression of starch degrading genes during imbibition of non-dormant seeds. Release of dormancy due to after-ripening led to the upregulation of specific genes encoding α-amylase and α-glucosidase during imbibition while dormancy maintenance is associated with repression of these genes...

Nitrogen (N) availability is an essential factor for plant growth. Recycling and remobilization of N have strong impacts on crop yield and quality under N deficiency. Autophagy is a critical nutrient-recycling process that facilitates remobilization under starvation. We previously showed that an important AuTophaGy (ATG) protein from apple, MdATG18a, has a positive role in drought tolerance. In this study, we explored its biological role in response to low-N. Overexpression of MdATG18a in both Arabidopsis and apple improved tolerance to N-depletion and caused a greater accumulation of anthocyanin...
