As climate change accelerates, understanding how crops survive environmental stress isn’t just an academic question—it’s a critical challenge for global food security. Tomatoes (Solanum lycopersicum), a staple crop worldwide, face increasing threats from drought, salinity, and extreme temperatures. But how do these plants adapt at the molecular level?
A recent study published in Scientific Reports investigated the evolutionary history, genomic diversity, and functional roles of protein phosphatase 2C (PP2C) genes in tomatoes (1). Instead of merely cataloging these genes, the researchers analyzed how PP2C gene expression changes under environmental stress. This information could help inform us about crop improvement strategies.
The Mozambique Channel, which is located between the Madagascar and Mozambique on the African coast, is an important hot spot for biodiversity because its many coastal ecosystems provide a range of habitats that support diverse plant and animal species. Understanding the biodiversity of an ecosystem, particularly biodiversity hot spots, is important for many reasons. For marine systems, accurate classification and reporting of fish species supports fisheries research, natural resource surveys, forensic studies, conservation studies, and enables discovery of new or under-reported species. Studies have been limited along the west coast of Africa and are only now in their early stages.
A 2024 research study by Muhala and colleagues applied DNA barcoding to evaluate the composition of marine and coastal fish diversity from the Mozambican coast. In the study, the Wizard® Genomic DNA Purification Kit was used to extract DNA from both teleost (ray-finned) and elasmobranch (sharks, rays and skates) fish classes, with a total of 143 species sampled from local artisanal fisheries along the Mozambican coast. The samples were primarily composed of muscle or fin tissues, which are ideal for genetic analysis due to their higher DNA yield. These tissue samples were collected from various fish species captured along the coast of Mozambique, stored in ethanol (96%) to preserve DNA integrity, and then processed using the Wizard kit. Total genomic DNA was extracted from the muscle or fin tissues, as per the manufacturer’s protocol. This method ensures the isolation of high-quality genomic DNA, which is crucial for subsequent polymerase chain reaction (PCR) amplification and sequencing. The COI gene (cytochrome c oxidase subunit I) was targeted for DNA barcoding, enabling species identification and assessment of genetic diversity.
In genetics, sizes often come with surprises. One tiny fern, Tmesipteris oblanceolata, also known as the Fork Fern, proved this phrase true, taking the scientific community by storm when it broke the record for the largest known genome. Researchers reported this discovery on May 31, 2024, stating that the plant, which is small enough to fit in the palm of your hand, harbors a full set of genetic instructions over 50 times the size of the human genome.
Projections from the United Nations suggest that the global population reached 8 billion in 2022. By 2030, the United Nations expect the population will grow to 8.5 billion (1). In order to sustain the rapidly expanding global population, innovative approaches in the agriculture sector are required to ensure food security and safety while maintaining sustainable practices.
Centuries of cultivating crops and raising livestock have honed our current agricultural methods. In the 21st century, these techniques encounter persistent challenges. Environmental factors such as soil degradation, water scarcity, and climate change pose significant threats to production. Additionally, the constant risks posed by pests and diseases can devastate both crops and livestock.
The agriculture sector’s challenge of feeding the world sustainably lies in the limited access to natural resources like land and water. Unfortunately, these resources don’t grow with our population, so we need to find a way to increase productivity per unit of land (2). Ideally, using less water and potentially harmful pesticides.
Biotechnology offers innovative solutions that support sustainable agriculture practices to not only enhance food production, but also increase nutritional value and safety of our food supply.
Biotechnology in Agriculture: Enhancing Crop Yield and Resilience:
For much of the history of agriculture, breeding programs have involved selectively breeding desirable traits to increase yield, quality, and resilience. In the age of biotechnology, agriculturalists are revolutionizing this practice with the help of cloning and CRISPR technologies.
Farmers everywhere strive to protect their crops and ensure a stable food supply while minimizing environmental harm. A promising approach to achieving this leverages a plant’s built-in defense mechanisms, reducing the need for chemical interventions. Many geneticists and agronomists lean on technologies that can automate and streamline nucleic acid extraction and pathogen detection to identify naturally pest resistant crops and, ultimately, keep up with the changing agricultural landscape.
The WSPCP works to provide seed potato growers with healthy planting stock
The mighty potato—the Midwest’s root vegetable of choice—is susceptible to a variety of diseases that, without proper safeguards, can spell doom for your favorite side dishes. Founded in 1913 and housed in the Department of Plant Pathology at the University of Wisconsin-Madison, the Wisconsin Seed Potato Certification Program (WSPCP) helps Wisconsin seed potato growers maintain healthy, profitable potato crops year-to-year through routine field inspections, a post-harvest grow-out and laboratory testing.
While WSPCP conducts visual inspections for various seed potato pathogens, their diagnostic laboratory testing is primarily focused on viruses such as Potato virus Y (PVY), which can cause yield reduction and tuber defects, along with select bacteria such as Dickeya and Pectobacterium species that cause symptoms like wilting, stem rot and tuber decay.
Boasting a biomass of roughly 400 million tons, Antarctic krill are a key source of food for a wide array of marine life, including sea birds, seals, penguins and whales. As with the rest of the oceanic ecosystem, krill are subject to rapidly shifting climate conditions, prompting scientists to seek a deeper understanding of how they might adapt to a changing environment.
Facing a general lack of genetic information on the species, Professors Cristiano De Pittà and Gabriele Sales from the Department of Biology at the University of Padova in Italy set out to define the krill transcriptome, or sequences of ribonucleic acid (RNA), and in doing so facilitated the discovery of key gene sequences that may play important roles in krill reproduction and survival.
In recent years, there have been concerns about potential impacts to the krill population from ocean warming and commercial fishing operations. Mapping the krill transcriptome may offer scientists crucial insight into the effects of climate change and anthropogenic activity on the dynamics of the Antarctic ecosystem. Doing so is no small feat. Though krill may be miniscule, their genome is 15 times the size of the human genome.
To this end, the research groups of De Pittà and Sales established the database KrillDB, providing a single resource where scientists can access a comprehensive catalogue of krill genes and RNA transcripts. This database represented a powerful bioinformatic tool for examining molecular processes in krill. Funded in part by the Promega 2019 qPCR Grant Program, researchers subsequently rolled out an updated database, KrillDB2, which includes improvements to the quality and breadth of the sequences covered and the information associated. Their corresponding study, published summer 2022 in Scientific Reports, identified a series of genes involved in the krill molting cycle, the reproductive process and sexual maturation, and included never-before reported insights into the expression of microRNA precursors and their effect on krill physiology.
The 2019 Promega qPCR Grant Program offered recipients $10,000 in free PCR reagents and related products, as well as access to Promega technical services and training teams.
Researcher and awardee Alberto Biscontin said of the grant’s impact on their project: “RNA sequencing approaches allow us to determine the level of expression of thousands of genes with a single experiment. The standard in the field is to define transcript expression levels by quantitative RT-PCR to technically validate RNA-seq results. We have been relying on the GoTaq® qPCR solutions by Promega for years.” He added, “We have used the GoTaq® 1-Step RT-qPCR System to compare the level of expression of candidate genes with those obtained from RNA-seq analysis. This allowed us to verify at any time the reliability of our bioinformatics pipelines.”
In the future, researchers plan to maintain the KrillDB2 database with the latest genome and transcriptome sequencing data, to provide the most comprehensive integrative analysis possible. They intend to develop a multi-crustaceans database to support future comparative genomics studies. The KrillDB2 database may also serve as a model to develop other databases for similar species.
