These examples illustrate the principles involved in leaf development, but there are many deviations associated with variations in leaf form.
Animals involved in leaf litter breakdown (i.e., shredders) play a central role in detritus-based stream food webs, while their fitness and functioning can be impaired by anthropogenic stressors.
In this sense, according to Qi et al. (2008), the gene Nal1 involved in leaf size, veining pattern and carboxylation is located within qTSN4.
All these results suggest that a micro-organism is involved in leaf litter toxicity.
These phenotypes are also observed in a tas3a insertion mutant, suggesting that TAS3a is the major TAS locus involved in leaf development [8].
Analysis of our microarray and RT-PCR data for several known genes involved in leaf morphology such as ANGUSTIFOLIA (AN), ROT3 [40], AN3 [42], CURLY LEAF (CLF) [43], DRL [44], AS1 [45], AS2 [46] and ATHB13 [47], however, did not reveal a significant change in their expression level between the mutant and WT (Figure S2 and Table S2).
Another paralog, AtMYB55, is involved in leaf development [ 81].
Both are involved in leaf development, floral organ identity and flowering time [ 21, 26- 28].
Several investigations have shown that bulliform cells are involved in leaf rolling [ 2, 59].
A microarray analysis about dark-induced miRNAs involved in leaf senescence are present here.
Also, SAG20, SIRK and WRKY22 are reportedly involved in leaf senescence [ 33, 34].
