A century of theories of balancing selection
Biological Reviews, EarlyView.ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.

Assessing morpho-chemical and genetic diversity in acid limes germplasm using microsatellite markers
Notulae Botanicae Horti Agrobotanici Cluj-NapocaAcid limes are highly nutraceutical and have great market demand. In Pakistan, two lime varieties are cultivated including ‘Mexican lime’ and ‘Eustis limequat’. Hence, other potential varieties were characterized for morphogenetic variability.

Entomologia Experimentalis et Applicata, EarlyView.In this study, we investigated the effects of blueberry domestication on the oviposition behavior and performance of Ganaspis kimorum, a parasitoid of Drosophila suzukii. Domestication of blueberries reduced the oviposition‐searching behavior of the parasitoid but enhanced parasitoid performance, including offspring performance. Additionally, blueberry

Exploring the relationship between tychoparthenogenesis and inbreeding depression in the Desert Locust, Schistocerca gregaria [PDF]
, 2017 Tychoparthenogenesis, a form of asexual reproduction in which a small proportion of unfertilized eggs can hatch spontaneously, could be an intermediate evolutionary link in the transition from sexual to parthenogenetic reproduction.

Entomologia Experimentalis et Applicata, EarlyView.Aster yellows phytoplasma (AYp) infection alters host plant preference in aster leafhoppers (Macrosteles quadrilineatus), with infected vectors showing a significant preference for AYp‐infected canola (Brassica napus) early in the infection period. However, this preference fades as infection progresses. Despite early attraction, B.

Neoplasia: An International Journal for Oncology Research, 2001 The way in which cytogenetic aberrations develop in prostate cancer (Cap) is poorly understood. Spectral karyotype (SKY) analysis of Cap cell lines has shown that they have unstable karyotypes and also have features associated with chromosomal ...

A comparison of methods for determining ploidy in white sturgeon (Acipenser transmontanus) [PDF]
, 2019 Release of sturgeon with abnormal ploidy into the wild may result in reduced fitness due to lowered fertility in the F2 and subsequent generations. Further, there is evidence that ploidy affects reproductive development and caviar yield.

Mutations and amplification of oncogenes in endometrial cancer [PDF]
, 1999 Alterations in oncogenes are critical steps in the development of endometrial cancer. To investigate the potential clinical relevance of the amplification of the oncogenes c-erbB2, c-myc, and int-2 and the mutation of K-ras in endometrial cancer, 112 ...

The FEBS Journal, EarlyView.KDM4A, a chromatin eraser, localizes to the centrosomes. Its demethylase activity is essential for maintaining centrosome number and integrity, independent of gene expression changes. Loss of KDM4A leads to centrosome amplification, pseudo‐bipolar spindle formation, and chromosome segregation errors, including micronuclei and chromatin bridges.
