Deinococcus grandis is a radioresistant bacterium isolated from freshwater fish in Japan. Here we reported the draft genome sequence of D. grandis (4.1 Mb), which will be useful for elucidating the common principles of radioresistance in Deinococcus species through the comparative analysis of genomic sequences.

Vitellogenin (Vg), a yolk protein precursor, is the primary egg nutrient source involved in insect reproduction and embryo development. The Cotton Boll weevil (CBW) Anthonomus grandis Boheman, the most important cotton pest in Americas, accumulates large amounts of Vg during reproduction. However, the precise role of this protein during embryo development in this insect remains unknown. Herein,...

M any flagellated species of bacteria can swim in liquids and glide along surfaces, while motile species without flagella only can glide. Much is known about flagella, whose rotary mechanism is believed to be universal. By contrast, gliding motility is a term used to describe various movements on surfaces by several different mechanisms, none of which is fully understood. Saprospira grandis, me...

In this study, we measured the composition and free radical scavenging activity of several species of nuts, namely, Torreya grandis, Carya cathayensis,and Myrica rubra. The nut kernels of the aforementioned species are rich in fatty acids, particularly in unsaturated fatty acids, and have 51% oil content. T. grandis and C. cathayensis are mostly produced in ZheJiang province. The trace elements...

The ability of prey to respond to predators is especially important in human-altered habitats, where prey are faced with changing predator regimes. A growing body of research has shown the important ecological impacts of intraspecific, individual differences in behavior, but few studies have shown direct fitness consequences of behavioral types in a predation context. We examined behavioral syn...

The female of Tropidonotacris grandis is described and information on distribution, habitat, song, chromosomes and nymphal development of this species given. The populations of northern Tanzania all occur in deciduous dry forest, a habitat highly endangered by destruction and therefore T. grandis must be regarded at least as a vulnerable species according to the IUCN red list. 

Nghiên cứu được thực hiện nhằm xác định giống và tuổi gốc ghép, kích thước chồi ghép nồng độ NAA phù hợp cho vi bưởi Năm roi trong điều kiện in vivo. Các thí nghiệm bố trí hoàn toàn ngẫu nhiên hai nhân tố, tỷ lệ sống (TLS) sự sinh trưởng của ghi nhận 3 ngày/lần 30 ngày. Kết quả thấy:TLS trên cam Mật, Lông, Sành, Hạnh, Chanh ở 7, 11 15 ngày đều thấp; 7 (lõi chưa hóa gỗ) thích ghép. Tiền xử lý mộ...

Bưởi Năm Roi (Citrus grandis (L.) Osbeck) là một giống bưởi đặc trưng ở vùng đồng bằng sông Cửu Long với lớp vỏ trắng chiếm gần 30% khối lượng quả bưởi, nguồn nguyên liệu có tiềm năng để thu nhận pectin. Phương pháp trích ly pectin hỗ trợ nhiệt đơn giản và dễ thực hiện giúp tăng hiệu suất ly. Các thông số được khảo sát trong quá trình từ kích thước bột loại dung dịch acid ly, pH acid, tỷ lệ bưở...

Thorough understanding of kinetics plays a key role in improving existing industrial processes. In this study, we attempted to model the hydro-distillation process that produces essential oil from peels pomelo (Citrus grandis L.) fruit, which is product with high economic value and wide range applications. We first determined optimal water-to-material ratio for attaining maximal yield. Then, fu...
