Sustainable value added material use of occurring by-products from sugar and rice production in Vietnam.

Due to the worldwide growing population, the demand on food increases, which results in the need for a higher productivity in agriculture. Generally, this leads to larger amounts of agricultural residues and by-products, which may cause severe environmental risks due to emissions from simple burning or storing, especially in emerging and developing countries. In Vietnam agricultural by-products arise in total of 118 Mt per year, whereas 80% are coming from rice and sugar cane processing.

A genome-wide association study using a Vietnamese landrace panel of rice (Oryza sativa) reveals new QTLs controlling panicle morphological traits.

Context: Yield improvement is an important issue for rice breeding. Panicle architecture is one of the key components of rice yield and exhibits a large diversity. To identify the morphological and genetic determinants of panicle architecture, we performed a detailed phenotypic analysis and a genome-wide association study (GWAS) using an original panel of Vietnamese landraces.

Sub-cellular markers highlight intracellular dynamics of membrane proteins in response to abiotic treatments in rice.

Background: Cell biology approach using membrane protein markers tagged with fluorescent proteins highlights the dynamic behaviour of plant cell membranes, not only in the standard but also in changing environmental conditions. In the past, this strategy has been extensively developed in plant models such as Arabidopsis.

Results: Here, we generated a set of transgenic lines expressing membrane protein markers to extend this approach to rice, one of the most cultivated crop in the world and an emerging plant model.

P2 of Rice grassy stunt virus (RGSV) and p6 and p9 of Rice ragged stunt virus (RRSV) isolates from Vietnam exert suppressor activity on the RNA silencing pathway.

In Vietnam, the two main viruses that cause disease in rice are the Rice grassy stunt virus (RGSV) and the Rice ragged stunt virus (RRSV). Outbreaks of these two viruses have dramatically decreased rice production in Vietnam. Because natural resistance genes are unknown, an RNAi strategy may be an alternative method to develop resistance to RGSV and RRSV.
