October 14, 2019QT:{{”
Witch’s broom can be caused by cytokinin, a phytohormone, interfering with an auxin-regulated bud. In normal plant function, an auxin would keep the secondary, tertiary, and so on tips from overgrowing, but cytokinin can sometimes interfere with this control, causing these apices to grow into witch’s brooms.
Witch’s broom may be caused by many different types of organisms, including fungi, oomycetes, insects, mistletoe, dwarf mistletoes, mites, nematodes, phytoplasmas, or viruses.[4] The broom growths may last for many years, typically for the life of the host plant. Human activity is sometimes behind the introduction of these organisms, for example, by failing to observe hygienic practice and thereby infecting the tree with the causative organism, or by pruning a tree improperly, and thereby weakening it.

Chimera (genetics) – Wikipedia
October 14, 2019QT:{{”
Tetragametic chimerism is a form of congenital chimerism. This condition occurs through the fertilisation of two separate ova by two sperm, followed by aggregation of the two at the blastocyst or zygote stages. This results in the development of an organism with
intermingled cell lines. Put another way, the chimera is formed from the merging of two nonidentical twins (a similar merging presumably occurs with identical twins, but as their genotypes are not
significantly distinct, the resulting individual would not be considered a chimera). As such, they can be male, female, or have mixed intersex characteristics.

The word ‘precision’ has become a synonym for the application of data to the analysis and treatment of a wide range of phenomena. ‘Precision medicine’ describes the use of detailed patient information to individualize treatment and prevention based on genes, environment and lifestyle, while ‘precision agriculture’ has become an entire field of R&D focused on ‘engineering technology, sensor systems, computational techniques, positioning systems and control systems for site-specific application’ in the farming sector.
….termed ‘precision electioneering.’ Data-driven precision is therefore both a source of scientific certainty and of controversy and contestation.
Emerging interests in ‘precision education’ foresee the concerted use of learner data for purposes of implementing individualized
educational practices and ‘targeted learning.’ As precision education has been described on the Blog on Learning and Development (BOLD): “}}
