  • Lady baltimore cake

    A cake composed exclusively of whipped egg whites, distinct from the Lord Baltimore cake, which exclusively utilizes egg yolks. The filling nestled between the layers is comparable to that of the Lord Baltimore, yet frequently simpler, forgoing the addition of nut meats and candied fruit. This dessert is a type of cake that features a…

  • Luteal

    The period when the corpus luteum, a temporary endocrine gland, secretes the hormone progesterone, which readies the uterine lining for possible embryo implantation. This time frame marks the second half of the menstrual cycle, from the release of the egg during ovulation until the start of the next menstrual period.  

  • L-carnitine

    This substance is responsible for acting as a carrier protein that facilitates the transportation of long-chain fatty acids into the mitochondrial matrix.  

  • logarithmic spray

    A device designed for the distribution of a solution in a manner whereby the concentration of the solution diminishes in an exponential manner over a period of time or distance.  

  • Lysogenization

    When a bacterium is invaded by a phage, it may result in the creation of a lysogenic clone or subclone of descendants. However, lysogenization typically occurs some time after the initial infection, often after several bacterial generations have passed.  

  • Lysogenic bacterium

    A bacterium infected with phage, which is integrated with the bacterial genetic material. All progeny are likewise infected and have the capacity to produce phage (by occasional cells undergoing lysis spontaneously or after application of inducing agents, e.g. ultra-violet light). Lysogenic bacteria are not sensitive to the phage they carry.  

  • Local lesion host

    A living organism that exhibits the emergence of confined wounds upon injection with a viral agent.  

  • Local lesion assay

    This is a method used to quantitatively determine the degree of infection caused by a pathogen. Typically, a sample of the pathogen, such as a suspension of bacteria or viruses, is inoculated onto leaves, and the number of lesions that develop is measured. The experimental unit used is typically a half-leaf, as the leaves of…

  • Lignituber

    A structure resembling a peg, which results from the host cell wall’s growth in response to the penetration of a fungal hypha, and appears to be made up of lignin, as it encases the hypha.  

  • Lesion test

    A methodology exists for gauging the potential of an organism to trigger a necrotic injury on plant material, specifically bean pods, by exposing it to a high dose of inoculum. However, it should be noted that this approach does not provide a reliable indication of the organism’s ability to infect in an actual field setting.…
