Which of the following photoreceptors are responsible for the red/far-red photoreversibility of light sensitive lettuce seed germination?

Resistance to stresses in the environment that is acquired genetically in a species through evolutionary processes is called what?

The terpenoid pathway is involved in synthesis of these hormones.

This hormone can stimulate bolting (sometimes flowering) in long-day plants.

The list below includes several reasons why high levels of salinity are INDIRECTLY injurious to most plants. Choose the SECOND of the two options in the list that indicates INDIRECT reasons why saline soils are harmful to most plants.

This hormone causes epinasty directly (rather than indirectly); for example, in anaerobic conditions.

This hormone breaks dormancy in VARIOUS tissues (BOTH seed AND bud tissues).

Which plant phytochrome responses are photoreversible?

This hormone directly triggers abscission.

  Specific mechanisms for saline tolerance:  Earlier in the test, in questions 51 and 52, you were asked about two general strategies which allow some plant species to tolerate saline conditions.  For this bonus question, type each of those general strategies here, and then below each one, describe at least two specific mechanisms of salt tolerance for each of those general strategies, including all relevant details. Every specific mechanism should be typed on a separate line.
