Self-incompatibility (SI) is one of the important factors that can result in seedless fruit in Citrus. However, the molecular mechanism of SI in Citrus is not yet clear. In this study, two suppression subtractive hybridization (SSH) libraries (forward, F and reverse, R) were constructed to isolate differentially expressed genes in pollen from "Wuzishatangju" (SI) and "Shatangju" (self-compatibi...

Self-incompatibility (SI) in flowering plants entails the inhibition of fertilization by pollen that express specificities in common with the pistil. In species of the Solanaceae, Rosaceae, and Scrophulariaceae, the inhibiting factor is an extracellular ribonuclease (S-RNase) secreted by stylar tissue. A distinct but as yet unknown gene (provisionally called pollen-S) appears to determine the s...

Breakdown of self-incompatibility occurs repeatedly in flowering plants with important evolutionary consequences. In plant families in which self-incompatibility is mediated by S-RNases, previous evidence suggests that polyploidy may often directly cause self-compatibility through the formation of diploid pollen grains. We use three approaches to examine relationships between self-incompatibili...

to enrich our understanding of the attitudinal/motivational basis of foreign language learning at junior high school level, this study investigated the students’ status of l2 motivation, the relationship between motivational factors, and the possibility of predicting their motivated learning behavior in light of dörnyei’s (2005, 2009) theory of l2 motivational self system. to this end, 1462 jun...

objective: we aimed to determine the relationship between self-efficacy and alexithymia with vulnerability to drug abuse among students. methods: the study method was descriptive and correlational. in this study, 483 male high-school students from salmas city, iran were selected by multi-stage cluster sampling method. all participants completed the toronto alexithymia scale, general self-effica...

In this note I examine the two main differences between Plato's and Dennett's views of the self as an abstract object. I point out that in the presence of certain forms of ontological realism, abstract-object theories of the self are compatible with the full reality of the self. I conclude with some remarks on the relationship between ontology and ethics.
