Thus, DME and TDG have reciprocal specificities with respect to the oxidized derivatives that may reflect the fact that the 5mC oxidation pathway is not needed in plants.
Similarly, most wasp species have only one recorded fig host, leading to the famous 1 1 rule of reciprocal partner specificity.
This association was long considered to be a textbook example of extreme reciprocal partner specificity, with each fig species having a unique pollinator species [ 9].
Our study offers a striking example of extreme deviation from reciprocal partner specificity over the full geographical range of a fig-wasp system.
Historically, they were considered to exemplify extreme reciprocal partner specificity (one-to-one host-symbiont species relationships), but recent work has revealed several more complex cases.
It is now clear that the paradigm of one-to-one reciprocal partner specificity is no longer tenable [ 9, 22], but true patterns of partner species associations remain to be revealed.
In this paper, based on reciprocal chiral substrate specificity, taking achiral molecules, ethanolamine (EA) and malachite green (MG) as two model targets, biostable L- DNA aptamers and L-RNA aptamers were generated respectively by chiral inversion of existing D-aptamers.
Increasing or decreasing sensitivity causes a reciprocal change in specificity.
Using a combination of the specificity of reciprocal ETA, which achieves the near 100% predictive accuracy, and the sensitivity of non-reciprocal ETA, which provides additional results, yields a desirable balance of sensitivity and specificity for functional annotation.
Here, the gain in annotation specificity from reciprocal matching is rooted in the fact that given two proteins S and T with respective templates s and t, then s≠t unless S and T are close homologs (and their cross-annotation trivial).
