WEP 2014: Dr. Michael Purugganan - The Origins of Crop Species

KAUST ·

NYU Professor Michael Purugganan presented at KAUST's 2014 Winter Enrichment Program (WEP 2014) on the origins of crop species. He discussed how genome sequencing is improving our understanding of crop evolution, using date fruits collected in Jeddah as an example. His research on rice showed that two varieties, japonica and indica, share a single common ancestor, contrary to previous assumptions. Why it matters: Understanding crop evolution can help adapt crops to changing environments, which is crucial for food security in regions like the Middle East.

​Carlos Duarte's Eelgrass research published in Nature ​

KAUST ·

KAUST's Professor Carlos Duarte contributed to sequencing the genome of Zostera marina (eelgrass), work published in Nature. The research identifies gene loss and adaptation mechanisms related to the plant's transition from land to marine environments. Eelgrass developed salt resistance, which could inform selective breeding for salt-tolerant food crops. Why it matters: Understanding the eelgrass genome can help in conservation efforts and provide insights into plant adaptation to climate change and marine environments.

Collaborative Work on Stress-Tolerant Crop Plants

KAUST ·

KAUST professors Samir Hamdan and Nina Fedoroff collaborated on research published in Nucleic Acids Research focusing on microRNA (miRNA) biogenesis in plants. The study examined miRNA production in Arabidopsis thaliana and found that the protein SERRATE (SE) is integral to the processing of pri-miRNA by DCL1. They characterized the interactions of SE with RNA and DCL1, elucidating the mechanism by which SE promotes DCL1 activity. Why it matters: Understanding miRNA biogenesis could help modify crop plants to better tolerate stressful conditions, potentially increasing crop yields and productivity in the region.

Genetic secrets of rice pave way for future farming and conservation

KAUST ·

KAUST researchers have published a study in Nature Genetics detailing genomic analysis of wild rice relatives. The study examined nine tetraploid and two diploid wild relatives of rice, finding significant genetic diversity due to transposable elements. This diversity includes genes that confer resilience to heat, drought, and salinity. Why it matters: These findings can help improve rice yields, introduce rice cultivation to currently untenable regions, and protect rice crops against climate change, especially in the Middle East.

Unravelling the secrets of modern wheat genetics

KAUST ·

KAUST researchers have developed a genomic resource for Tausch’s goatgrass (Aegilops tauschii), a wild relative of wheat, by creating 46 high-quality genome assemblies. They compiled 493 genetically distinct accessions from an initial 900, collaborating with the Open Wild Wheat Consortium to select accessions with traits of interest, such as disease resistance and stress tolerance. Screening these assemblies helped identify rust resistance genes, including mapping a stem rust resistance gene to the Sr33 locus. Why it matters: This genomic resource will accelerate gene discovery in wheat, potentially improving modern wheat varieties and enhancing global food security.

Promising field of urban science highlighted at 2015 WEP keynote lecture

KAUST ·

Michael Holland from NYU's Center for Urban Science & Progress (CUSP) presented a keynote lecture at KAUST's Winter Enrichment Program (WEP) 2015 on the importance of urban science. CUSP, launched in 2012, aims to make New York City a world capital of science and technology through multi-sector research and education. Holland emphasized how analyzing urban data can improve city government, planning, policy, and citizen engagement. Why it matters: As urbanization increases, the development of urban science and the effective use of urban data become crucial for sustainable and efficient city management in the GCC region and globally.

Shining a light on the SARS-CoV-2 virus

KAUST ·

The KAUST Pathogen Genomics Laboratory (PGL), led by Professor Arnab Pain, is using DNA and RNA sequencing to study the SARS-CoV-2 virus. The lab is part of KAUST's Rapid Research Response Team (R3T), supporting Saudi healthcare stakeholders in combating COVID-19. Pain and his Ph.D. student Sharif Hala are partnering with the Saudi-CDC and Ministry of Health hospitals to sequence Saudi SARS-CoV-2 samples. Why it matters: This effort provides crucial data for understanding and monitoring the virus's spread and evolution within the Kingdom, informing public health strategies.

What makes the human aging clock tick?

KAUST ·

Juan Carlos Izpisua Belmonte from the Salk Institute discussed aging and regenerative medicine at the KAUST 2019 Winter Enrichment Program. His team is combining gene editing and stem cell technologies to grow rat organs in mice and human cells in pig and cattle embryos. The Salk team is collaborating with KAUST to rejuvenate organs using noncoding RNAs and small metabolites. Why it matters: This research collaboration between KAUST and the Salk Institute explores innovative approaches to address age-related diseases and organ regeneration, with potential long-term impacts on healthcare in the region.
