    Summary:
    How does one help save an iconic, nutritious Egyptian crop that
    will help meet the food security challenges resulting from climate
    change? An international team of researchers discovered that the
    best way to start is to drive throughout central and northeastern
    Egypt, knock on the doors of small farmers, and ask for a handful
    of their pumpkin seeds.

    How does one help save an iconic, nutritious Egyptian crop that will
    help meet the food security challenges resulting from climate change? An international team of researchers, led by the University of Massachusetts Amherst, discovered that the best way to start is to drive throughout
    central and northeastern Egypt, knock on the doors of small farmers,
    and ask for a handful of their pumpkin seeds.


    ==========================================================================
    The results of that labor, announced recently in Molecular Biology
    Reports, show that the team has successfully traced the biochemical
    and molecular variations of nine different pumpkin varieties grown in
    several climatic zones of central and northeastern Egypt. The research
    is a crucial first step in identifying which varieties of pumpkins are
    ideal for conservation and varietal improvement to meet the challenges
    in achieving food security in a changing world.

    In the United States, we typically think of pumpkins only in the fall,
    when they appear in pies, cookies and lattes. But in much of the world, pumpkins are a dietary staple and are consumed year-round. Pumpkins
    are an especially nutritious source of fat, protein, vitamins A, C and
    E and various disease- fighting compounds that help prevent everything
    from cancer to reproductive malfunctions. But, as Emad Mady, a graduate
    student in environmental conservation at UMass Amherst and the paper's
    lead author, notes, not all pumpkins are the same.

    "I first noticed this in Egypt," Mady says. Small Egyptian farmers have
    been growing the pumpkins for generations, patiently breeding them
    to thrive in the local conditions, which can vary widely across the
    country. However, large agricultural corporations have begun introducing pumpkin seeds to Egypt that are not native to the local conditions,
    threatening the survival of the traditional varieties. Moreover, because
    these newer commercial seeds have not been bred to the local conditions,
    they can actually exacerbate the problems of food insecurity "Our goal,"
    says Mady, "is to determine which pumpkin cultivars are best suited
    for the local environments, and then use these cultivars as the basis
    for furthering pumpkin production in Egyptian agriculture." To do so,
    Mady traveled across the country, visiting with small farmers, walking
    through their fields and collecting seeds. He then collaborated with
    colleagues in Egypt at Al-Azhar University and the Agricultural Genetic Engineering Research Institute who ran a series of chemical and molecular
    tests on the seeds before they could degrade. These tests helped identify
    the nutritional value of specific local varieties, including their fat, moisture, protein, fiber, mineral and carbohydrate content, as well
    as the genetic markers that function as a unique fingerprint for each
    specific variety.

    Once Mady's Egyptian colleagues completed their chemical and molecular
    work, he and his team at UMass Amherst and Springfield Technical Community College in the U.S. analyzed and categorize the findings. What they
    discovered is that there is significant variation in the nutritional value
    of the samples Mady collected, and that these varieties can be accurately identified using genetic analyses. Altogether, this collaboration of
    small farmers and international researchers has shown that local Egyptian pumpkins can be used to help develop future varieties that are highly nutritious and well adapted to Egypt's specific environment.

    "One of the biggest problems in meeting the world's food security
    challenges," says Timothy Randhir, professor of environmental conservation
    at UMass Amherst and one of the study's co-authors, "is an international collaboration that can integrate local knowledge and resources to bring
    about positive change. This research is a model of how the small farming community and the scientific community can work together to address
    these pressing needs."
