Maize heterochromatic knobs cheat female meiosis by forming neocentromeres that bias their segregation into the future egg cell. In this issue of , Swentowsky and colleagues (pp. 1239-1251) show that two types of knobs, those composed of 180-bp and TR1 sequences, recruit their own novel and divergent kinesin-14 family members to form neocentromeres.

The ability to modify and control natural and engineered microbiomes is essential for biotechnology and biomedicine. Fungi are critical members of most microbiomes, yet technology for modifying the fungal members of a microbiome has lagged far behind that for bacteria. Interdomain conjugation (IDC) is a promising approach, as DNA transfer from bacterial cells to yeast enables modification.

Fertility is economically important but is hard to quantify and measure in breeding programs which has led extensive breeding programs to ignore fertility in their selection criteria. While female fertility traits have been extensively researched, male fertility traits have been largely ignored. It is estimated that 20% to 40% of bulls have sub-fertility, reducing the number of calves born and profits, highlighting the importance of investigating bull fertility.

Introduction: Despite all the advantages of urban family physician program (UFPP), there is still a gap between UFPP and what is actually achieved by the community after its implementation in Iran. In response, this study attempted to review published studies related to the barriers to the implementation of the UFPP in Iran as well as potential solutions to improve it. Further, a qualitative study was conducted to learn the perspectives of experts at the national level and in the Fars province in order to better understand the program's challenges.
