The membrane-bound, long form of MGAT4D, termed MGAT4D-L, inhibits MGAT1 activity in transfected cells and reduces the generation of complex N-glycans. MGAT1 is the GlcNAc-transferase that initiates complex and hybrid N-glycan synthesis. We show here that Drosophila MGAT1 was also

Abiotic stress tolerance of plants is a very complex trait and involves multiple physiological and biochemical processes. Thus, the improvement of plant stress tolerance should involve pyramiding of multiple genes. In the present study, we report the construction and application

Hygromycin B, an aminocyclitol antibiotic that strongly inhibits both 70S and 80S ribosomes, is synthesized by Streptomyces hygroscopicus. Ribosomes from this Gram-positive mycelial bacterium are inhibited in vitro by the antibiotic. In contrast, the streptomycete is highly resistant to the
