The second, ICESsuBM4072, is found at the same locus as ICESsuSC84; the element is inserted into the 3-prime region of the gene encoding the 50S ribosomal protein L7/L12 (SSUBM407_0933).
When the number of elements of H is smaller than its expected size (i.e. k), and a new element L arrives, the element is inserted into H and H is adjusted to maintain the max heap property.
If the above condition is satisfied, then the element is inserted as a child node, or it will find the closest node at the subsequent levels of the QT by calculating minimum distance.
A third possibility is that selection acts more strongly on the Isis element (for example, if the element is inserted inside genes or regulatory regions) than on Osvaldo and, provided the Australian colonisation is recent, its effects are only detected in the element under the most selection pressure.
First of all the necessity to take into consideration even when, like in the case of yeast metabolic network, we concentrate on a single element (the lethal character of a specific mutation), the general frame in which the element is inserted.
Our present analysis of island STM4305 also allowed us to determine the sequence of the target site of the IS200 element found in this island in S. typhimurium strain LT2, and we propose that this element was inserted after the island had already been acquired by the S. typhimurium lineage.
R32 was found in the four O. glaberrima varieties, but absent in all Asian AA varieties, suggesting that this element was inserted into the African AA lineage after its divergence from the Asian AA lineage.
The elements are inserted in a node up to its capacity.
Qualitatively similar effects were obtained when the elements were inserted in the anti-sense orientation (Fig. 2).
In the B. rapa genome, 74.4 % of the elements were inserted in gene-rich regions, less than 3kb from genes.
