This biological basis is supported by the analysis of various mutants affected in floral meristem identity in different species, notably in Arabidopsis thaliana, Antirrhinum majus, petunia and tomato (Koes 2008; Moyroud et al. 2010; Park et al. 2014).
The study of mutants affected in the corresponding genes would be very useful to elucidate the plant carnitine biosynthetic pathway and to investigate further the role of carnitine in plant physiology.
The reduction of cytokinin levels in the phloem leads to a destabilization of the root vascular pattern in a manner similar to mutants affected in auxin transport or cytokinin signaling [7].
irx phenotypes have been reported for mutants affected in their cell wall composition.
Mutants affected in SA production or signal transduction show reduced resistance to Pst [39].
We have examined ABA production in esk1 mutants and the phenotypes of double mutants affected in ABA responses and esk1.
Similar phenotypes have been observed in mutants affected in various components of photosynthetic electron transport [21], [22], [23], [24], [25].
Mutants affected in helices α-3 or α-4 are thus affected in pore formation activity and completely lost toxicity against their target insect [5] [7].
lhp1 mutants are early flowering and have curled leaf morphology [26] thus sharing some phenotypic traits with curly leaf (clf) mutants affected in a PRC2 core component.
Out mutants are unable to cause maceration symptoms [7] and mutants affected in the Prt secretion system are delayed in symptom progression [8].
The DN phenotype cannot be observed in mutants affected in oligomerization, suggesting that this step is important to inhibit toxicity of other toxins.
