Extensive genetic and molecular studies performed in several model plant species have led to a broadly accepted model of flower development based on the combinatory activity of three gene functions which determine floral organ identity, i.e. the ABC model [3], [4].
A broadly accepted model for the genetic architecture of complex disease is the common disease – common variant (CDCV) hypothesis.
The ABCE model, a broadly accepted model of flower development that was first proposed two decades ago, describes how the combinatorial activity of four classes of homeotic genes determines floral organ identity [ 1– 5].
According to the more long-standing and broadly accepted model of mtDNA replication [ 41] (but see [ 42- 44]), and demonstrated for the few cases where it has been studied, replication of mtDNA is very slow and very asymmetrical, with one strand in single stranded form for a protracted period, so this may be an important factor in strand compositional bias.
Replanting native vegetation is a broadly accepted method for restoring degraded landscapes.
Currently molecular techniques are a broadly accepted tool for diagnosis and are able to benefit patients in clinical practice.
Assessing the TBEV prevalence in ticks through detection of genomic RNA is a broadly accepted approach to estimate the transmission risk from a tick bite.
