In tropical dry deciduous forests, where fires are very frequent, plants display some adaptive traits like thick bark, the capability of healing fire scars, seed adaptations, and re-sprouting capability (Khan and Tripathi 1986 , 1989.
Irrespective of the selection criteria, in general, animal CNSs tend to be much longer and more frequent than plant CNSs, and plant CNSs are shorter than animal CNSs.
This dominance of dimer SSRs in nine of 24 plants contradicts the general assumption that trimer SSRs are most frequent in plant ESTs [ 17].
In some other cases, genes even were acquired from other sources to help maintain obligate endosymbionts 37. HGT appears to be particularly frequent in plant mitochondria 38– 40, which often harbor mitochondrial genes from distantly related plants.
At these aphid densities, though, Host 2 was only infected by Y isolates, and much higher aphid densities (i ≥ 7) were required for N isolates to occur in mixed infection with A isolates and for M plants to be the most frequent infected plants; for all i values, S plants were the most prevalent (Fig. 3A).
The most frequent vascular plant species was the white goosefoot (Chenopodium album agg).
As a result, frequent process plant cleaning is needed, and cleaning-in-place (CIP) protocols are well- developed.
Tandem duplicates are frequent in plant genomes and represent up to 16% of Arabidopsis genes [ 31].
While "AT/TA" and "AG/TC" repeats were reported as the most frequent in plant genomes [ 17, 23- 29].
Although micro-repeat motifs are frequent in plant genomes and their respective transcriptomes, the frequency of SSR discovery depends on the search criteria [ 42, 54- 56].
