The utilization of heterosis among different species significantly enhances rice yield. However, the direct application of this advantage is hindered by hybrid sterility (HS). Here we identify a stable semi-sterile inbred line (SSIL) in the hybridization between rice species O. sativa indica and wild rice O. longistaminata. Both pollen and spikelet fertility in heterozygous SSIL plants are semi-sterile, and the homozygous plants show normal fertility. Interestingly, unlike previously reported hybrid sterility loci, SSIL does not induce segregation distortion in progeny.


A study conducted by researchers from China showed that two genetically modified (GM) insect-resistant maize events, CM 8101 and Reuifeng 8, reduced fumonisin pollution under the stress of Lepidopteran insects (Ostrinia furnacalis and Helicoverpa armigera). China, the world's second-largest maize producer, faces widespread fumonisin contamination caused by Fusarium spp. Fumonisins affect over 80% of corn-producing areas, with higher pollution levels seen in regions like Zhuozhou due to favorable conditions for fungal growth.

Embrapa Genetic Resources and Biotechnology in Brazil reports stable folate biofortification in lettuce under field conditions for two years. The results are published in Transgenic Research. Folate, also known as vitamin B9, is an essential nutrient that plays a vital role in several bodily functions. Deficiency in folate may cause health problems, including megaloblastic anemia, neural tube defects in the developing fetus, and increased risk of cardiovascular diseases.


The IAS Research Activities In 2024
Friday, 2025/01/17 | 15:44:30

In 2024, the IAS has drastically managed and conducted 32 scientific tasks with the fund of VND 21.8 billion (accounted for 64.5% budget). Beside, the IAS scientific service activities gained VND 12.1 billion (accounted for 35.5% budget). The scienticfic tasks of state level, ministry level, extension, international projects, local cooperation and team works occupied 8.1%, 13.7%, 13.3%, 3.7%, 14.2% and 11.6% R&D budget, respectively.

 


Agriculture has been recognized as a bright spot in the economic development of 2024. The agricultural and rural sector implements the 2024 Plan in the context of mixed advantages, difficulties and challenges; including the strong impact of market fluctuations, intense hot weather, drought, rainstorms in the Central Highlands and Central regions, salt intrusion in southern regions, Storm No. 3 (Yagi) caused heavy damage to the agricultural production (VND 31,800 billion lossed).
