The Arabidopsis genome encodes three types of Sec24 homologs (AtSec24A, AtSec24B, and AtSec24C). The subcellular dynamics and function of AtSec24A have been characterized. The intracellular distributions and functions of other AtSec24 proteins are not known, and the functional differences among the three AtSec24s remain unclear. Here, we found that all three AtSec24s were expressed in similar parts of the plant body and showed the same subcellular localization pattern. AtSec24B knockout plant, but not AtSec24C knockdown plant, showed mild male sterility with reduction of pollen germination. Significant decrease of AtSec24B

MEK inhibitor and AtSec24C expression affected male and female gametogenesis in Arabidopsis thaliana. Our results suggested that the redundant function of AtSec24B and AtSec24C is crucial for the development of plant reproductive cells. We propose that the COPII transport is involved in male and female gametogenesis in planta.”
“The microalgae Chlorella protothecoides UTEX 25, Chlorella sp. TISTR 8991, and Chlorella sp. TISTR 8990 Autophagy inhibitor were compared for use in the production of biomass and lipids under photoautotrophic conditions. Chlorella sp. TISTR 8990 was shown to be potentially suitable for

lipid production at 30A degrees C in a culture medium that contained only inorganic salts. For Chlorella sp. TISTR 8990 in optimal conditions in a stirred tank photobioreactor, SBI-0206965 datasheet the lipid productivity was 2.3 mg L(-1) h(-1) and after 14 days the biomass contained

more than 30% lipids by dry weight. To attain this, the nitrogen was provided as KNO(3) at an initial concentration of 2.05 g L(-1) and chelated ferric iron was added at a concentration of 1.2 x 10(-5) mol L(-1) on the ninth day. Under the same conditions in culture tubes (36 mm outer diameter), the biomass productivity was 2.8-fold greater than in the photobioreactor (0.125 m in diameter), but the lipid productivity was only 1.2-fold higher. Thus, the average low-light level in the photobioreactor actually increased the biomass specific lipid production compared to the culture tubes. A light-limited growth model closely agreed with the experimental profiles of biomass production, nitrogen consumption, and lipid production in the photobioreactor.”
“Injuries to the face may cause long-term defects both aesthetic and functional consequences when the treatment is delayed, inadequate or absent. The varieties of osteotomy techniques are applied to improve posttraumatic malposition of the maxillofacial bones and occlusal function. In this article, a 21-year-old female involved in a traffic accident presented a severe deformity in maxilla and treated by anterolateral osteotomy is presented.”
