In general, the hormones that regulate senescence can be divided into two basic categories based on their most commonly observed effects:

I) positive (promoting) senescence regulators and

II) negative (repressing) senescence regulators

a) Hormones involved-Ethylene, Abscisic acid (ABA)

b) Hormones involved-Brassinosteroids (BRs), Salicylic acid (SA), Jasmonic acid (JA)

c) Hormones involved-Cytokinin, Auxin, Gibberellin (GAs)

Precision will be reduced, but yield will be increased

Optimisation of a PCR reaction is often a compromise between the competing demands for precision, efficiency and yield. Although the specific effects may vary, generally, increasing the annealing temperature will increase non-specific primer binding and reduce precision. Increasing the length of the elongation phase will reduce the proportion of incomplete newly-synthesised strands and therefore increase yield. In this case, the potential effect on efficiency is unclear. Increasing the elongation phase would increase the reaction time, but the time taken to ramp down to a lower annealing temperature would be reduced.

Arrange in the order of their increasing capacity:
