#SCPH28 | Zoology

  1. this infection hasn't been observed in the human population prior to recent (approximately 50 years or sooner) outbreaks

  2. this disease has been in susceptible populations for centuries, but has only recently achieved infection levels that became detectable.

  3. the infectious agent is still evolving and changing, unlike with older, more established diseases such as plague or polio.

  4. the disease has always been in susceptible populations and causing disease, but we lacked the technology to detect it.

Some given facts regarding effector molecules such as;

a) HC-toxin-induced plasma membrane hyperpolarization in guard cells causes massive K+ uptake and permanent stomatal opening

b) Xanthomonas, are proteins that target the plant cell nucleus and causes change in gene expression, called transcription activator-like (TAL) effectors bind to the host plant DNA and activate the expression of genes

c) Fusicoccin, a cyclic peptide, acts on the enzyme histone deacetylase in the nucleus, and may have a compromising effect on the expression of genes involved in defense

d) Gibberellins accelerate growth, resulting in bigger plants when compared with uninfested plants. The gibberellins produced by the fungi are identical to those produced endogenously by the plant
