Heribert Hirt

Prof. Hirt’s research is focused on how plants can survive under abiotic or biotic stress conditions. The main interest lies in how protein kinases can reprogram gene expression. At KAUST, Prof. Hirt is establishing two research groups. One research group focuses on how MAP kinases target chromatin to prime stress tolerance at both the genetic and the epigenetic level. The other research group searches for rhizosphere microbes of desert plants and investigates their potential and mechanisms to induce stress tolerance in plants. Although the major part of these two projects is carried out in Arabidopsis, the generated knowledge will be applied to crop plants with the aim to provide sustainable solutions to reestablish agriculture in arid regions or under extreme environmental conditions.

Being a molecular biologist by training, I have developed a deep interest in Microbial genetics and bacterial adaptation to different niches. I am very fascinating by the dual life style of different bacteria as well different mechanisms used by bacteria to interact with different host and modulate the immune response of the host. Furthermore, the great potential of microbes in benefit of the humanity, as I believe the Microbes will be a solution of number of the global challenges.

My interest in Microbes started when I was a master student and got the chance to have a training period in BBA, Germany, and learn about the different diagnostic techniques to detection microbial infection of crop plants e.g. viruses, bacteria and plant fungus. Afterward, My research interest was more directed to the beneficial microbes with special emphases of symbiotic Nitrogen fixing bacteria named Sinorhizobium fredii NGR234, and how this bacteria could tune the plant defense system via number of effector protein secreted through the type three secretion systems (T3SS) which mainly used by pathogenic bacteria to onset diseases. Abolition of secretion of all or specific effector significantly alters the nodulation abilities of NGR234 on many of its hosts. To get more insight of the mechanisms of the adaptation of Nitrogen fixing bacteria and overcome the plant immune system, I join group of LIPM, France, as postdoc fellow. I applied different genomic and transcriptomics tools to understand and explore the rhizobia diversity and learn the common genetic functions required for symbiosis and pathogenesis. We succeed to complete the first genome sequence of a β-proteobacterial nitrogen-fixing symbiont of legumes, Cupriavidus taiwanensis LMG19424. Based on the genomic information we achieved to extend the host range of the rhizobia to be different legume host by modulating T3SS.

Post-doctoral Fellow

Lukas Synek

In 2002, I acquired my Master’s degree in virology and molecular biology at the Charles University in Prague. Then, I moved to the field of plant cell biology and physiology to the Institute of Experimental botany (Academy of Sciences of the Czech Republic, Prague), where I participated in research on the regulation of exocytosis, and where I completed my PhD (2007). I continued on this topic as a post-doc before moving to the Center of Desert Agriculture in KAUST (2015). I focus mainly on microscopic and genetic methods that help to elucidate processes in plant cells.

Post-doctoral Fellow

Cristina Andrés-Barrao

Born and raised in Zaragoza, Spain, I was since my early childhood fascinated by sciences, with the biggest interest in biological sciences. I obtained a Bachelor Degree in Chemistry at the University of Zaragoza, what I completed with a Master Degree in Organic Chemistry and another in Biochemistry.

To continue my academic formation and acquire the international experience that was avid, I was awarded with a European Community Action Scheme for the Mobility of University Students (Erasmus Mundus) Scholarship that brought me to Geneva, Switzerland. There, I join the group of Dr. Francois Barja, at the department of Plant Biology at the University of Geneva (UNIGE), to work with Dr. Marta Cotado (PhD student at that time) in a project related with the study of cytoskeletal proteins in the fungus Neurospora crassa. Already experiencing an increasing interest in microbiology, I decided to accept an offer of Dr. Barja and start a PhD on a relatively new research line of the group, acetic acid bacteria (AAB), studying the characterization of bacterial strains involved in acetic acid fermentation, their identification and taxonomy, and the resistance of these strains to high percentages of acetic acid. I applied molecular biology techniques and basic comparative genomics and had the pleasure to attend international conferences in Switzerland and Japan (Best Poster Award at the The 2nd International Conference on Acetic Acid Bacteria in 2008), and successfully defended my PhD thesis in September 2012.

After a short period as Postdoc in Dr. Barja group, I moved to Tokyo, Japan, thanks to a Postdoctoral fellowship awarded by the Japanese Society for the Promotion of Science (JSPS), to join the group of Prof. Akiko Okamoto-Kainuma, at the Tokyo University of Agriculture (NODAI). There, I continued my research on AAB working on a project that was mainly focused on the use of transcriptomics (RNA-Seq) to study the metabolism modifications of AAB during in vitro acetic acid fermentation mimicking the industrial production of vinegar.

At this stage, I had a renewed interest in extremophile microorganisms, and I was also keen to move forward to new fields, so I decided to accept an offer of Dr. Maged M. Saad, a previous colleague at the University in Geneva, to re-direct my research towards the study of plant growth-promoting bacteria (PGPB). In 2015 I joined the group of Prof. Heribert Hirt, at the King Abdullah University of Science and Technology (KAUST), to work on a research project (Darwin21, that aims to isolate and thoroughly characterize PGPB from desert endogenous plants, with the final goal to apply PGPB as alternative biofertilizer to improve agriculture in desert and arid regions.

Abdul Aziz Eida is from Beirut, Lebanon who was born and raised in Al-Khobar, Saudi Arabia. He completed his undergraduate studies at Jacobs University Bremen in Germany where he obtained a B.Sc. in Biotechnology. He then received his M.Sc. in Bioscience from KAUST in 2015 where he is currently pursuing his PhD. His research interests lie in the area of microbiology and plant biology, in both laboratory and field settings. His current project focuses on identifying the mechanisms involved in salt tolerance promotion of A. thaliana by plant growth promoting (PGP) bacteria from desert plants collected from Jizan, Saudi Arabia, and how these bacteria can then be applied for agricultural field applications on crop plants, such as wheat and barley. His work involves 16S rRNA gene sequence analysis (microbiome), chemical soil analysis, biochemical assays for PGP traits, phenotypic characterization of plants, genomics, and bacteria/plant transcriptomics. He has a keen interest for the phosphate solubilization aspect of PGP bacteria, and has recently published a book chapter on the challenges faced in field application of phosphate-solubilizing bacteria.

Ameerah Bokhari

I Joined the Hirt lab in November 2014 to pursue my PhD project in plant-associated microbes. My academic background consists of a masters degree in Bioscience from KAUST in Dec 2011 which was in addition to my Bachelors degree in Microbiology that I obtained from King AbdulAziz University in Jeddah in March of 2008. My general research interest is studying beneficial microorganisms with different industrial significance for sustainable food and energy.

In DARWIN21 project, my research interest was to study the communication and regulation mechanisms of beneficial plant-growth promoting bacteria (PGPB). These PGPB were associated with model plant Arabidopsis thaliana under abiotic stress conditions to study their ability to confer abiotic stress tolerance to plants. PGPB traits and mechanisms was studied using genomics, transcriptomics and functional analysis. As proposed by DARWIN21 project, the future goal is to generate a wide collection of different beneficial plant-associated microbes that can help improve crop resistance to different biotic and abiotic stresses in arid hot lands like Saudi Arabia.
