In response to sudden, 5 to 10°C rises in temperature, plants produce a unique set of proteins referred to as heat shock proteins (HSPs). There are five classes of heat shock proteins found in plants such as;

       HSP class

 Examples (Arabidopsis / prokaryotic)

      Cellular location

 

I) HSP100

 

 

a) AtTCP-1 / GroEL, GroES

 

i) Cytosol

 

II) HSP90

 

 

b) Various AtHSP22, AtHSP20, AtHSP18.2, AtHSP17.6 / IBPA/B

 

ii) mitochondria

 

III) HSP70

 

 

c) AtHSP101 / ClpB, ClpA/C

 

iii) chloroplasts

 

IV) HSP60

 

 

d) AtHSP70 / DnaK

 

iv) endoplasmic reticulum

 

V) smHSP

Shell coiling of the snail Limnaea peregra(genetic maternal effect)  the shell coils (s+s+) which is termed dextral coiling, while some snails exhibiting sinistral coiling (ss). The allele for dextral (s +) is dominant over the allele for sinistral (s). If a male homozygous for dextral alleles (s+s+) is crossed with a female homozygous for sinistral alleles (ss) all of the F1 are heterozygous (s+s) and have a sinistral shell. If these F1 snails are self-fertilized, what is the phenotype of the F2 snail?
