Ackee (, Sapindaceae) is a multipurpose fruit tree species of high economic importance, native to the Guinean forests of West Africa, and belongs to the same family as that of lychee (). In this study, a set of 12 primer pairs for simple sequence repeats (SSRs) previously developed for lychee has been evaluated for polymorphism in 16 ackee trees from different populations. Seven primer pairs have been found to be transferable, and four have revealed polymorphisms. However, the average number of alleles per locus has dropped from 4.9 for lychee to 3.7 for ackee. Characterization of the four polymorphic markers in 279 individuals belonging to14 different ackee populations from Benin has revealed that the numbers of alleles per locus range from two to 14 with a mean number of 5.8. The observed and expected heterozygosities range between 0.020 to 0.359 and 0.020 to 0.396, respectively.

Biological applications using multiphoton microscopy increasingly seek a larger field of view while maintaining sufficient temporal sampling to observe dynamic biological processes. Multiphoton imaging also requires high numerical aperture microscope objectives to realize efficient non-linear excitation and collection of fluorescence. This combination of low-magnification and high-numerical aperture poses a challenge for system design.

ConspectusSkeletal editing, which involves adding, deleting, or substituting single or multiple atoms within ring systems, has emerged as a transformative approach in modern synthetic chemistry. This innovative strategy addresses the ever-present demand for developing new drugs and advanced materials by enabling precise modifications of molecular frameworks without disrupting essential functional complexities. Ideally performed at late stages of synthesis, skeletal editing minimizes the need for the cost- and labor-intensive processes often associated with synthesis, thus accelerating the discovery and optimization of complex molecular architectures.

Meliorating the behavior deposition of lithium polysulfides (LiPS) is crucial for enhancing the electrochemical performance of sulfur cathodes, which could be implemented by the precise modulation on the catalytic host. Herein, heterostructure engineering is employed to tune up the catalytic capability of CeVO, by introducing CeO through a simple adjustment in the addition sequence of reactants. The formed CeVO/CeO heterostructure has been demonstrated to exhibit appropriate interaction strength with LiPS for accelerating the catalytic conversion process, as well as an engineered surface for inducing three dimensional (3D) LiS deposition, thereby endowing the corresponding sulfur cathodes with excellent electrochemical performance under harsh conditions.

Classical tissue recombination experiments demonstrate that cell-fate determination along the anterior-posterior axis of the Müllerian duct occurs prior to postnatal day 7 in mice. However, little is known about how these cell types are maintained in adults. In this study, we provide genetic evidence that a balance between antagonistic retinoic acid (RA) and estrogen signaling activity is required to maintain simple columnar cell fate in adult uterine epithelium.

In the pregenomic era, scientists were puzzled by the observation that haploid genome size (the C-value) did not correlate well with organismal complexity. This phenomenon, called the "C-value paradox," is mostly explained by the fact that protein-coding genes occupy only a small fraction of eukaryotic genomes. When the first genome sequences became available, scientists were even more surprised by the fact that the number of genes (G-value) was also a poor predictor of complexity, which gave rise to the "G-value paradox.
