Microtubule Inner Protein CFAP77 Contributes to Sperm Motility and Male Fertility in Mice

open access: yesAndrology, EarlyView.
ABSTRACT Background Sperm motility is essential for male fertility, and its regulation is dependent on the structural integrity of the axoneme. The axoneme consists of a conserved “9+2” microtubule arrangement and is supported by microtubule inner proteins. However, the functional significance of many microtubule inner proteins remains unclear.

Separation of integument and nucellar tissues from cotton ovules (Gossypium hirsutum L.) for both high- and low-throughput molecular applications

open access: yesBioTechniques, 2013
Here we present a quick and low-cost method to separate the different layers of tissue from the ovules and young seeds of cotton (Gossypium hirsutum L.) for use in high- and low-throughput molecular applications.

Transcription Factor TCF12‐Mediated Maternal Gene Expressions in Mouse Oocyte Are Prerequisites of Successful Fertilisation and Zygotic Genome Activation

open access: yesCell Proliferation, EarlyView.
Maternal TCF12 ensures the competence of fertilisation by controlling the expression of Astl and the proper location of cortical granules. Furthermore, maternal TCF12 maintains the phosphatase activity of PP2A by regulating the expression of Arpp19. Oocyte‐specific deletion of Tcf12 leads to fertilisation defects as well as ZGA failure at the 2‐cell ...

Solving the trophic puzzle: Host–parasite associations in Neotropical fig wasps associated with fig trees of section Americanae

open access: yesEcological Entomology, EarlyView.
We determined the trophic associations among fig wasp species associated with Ficus citrifolia by integrating gall morphology, the temporal sequence of wasp colonization, and oviposition behaviour. Dissection of galls produced by four gall‐inducing species at a late developmental phase enabled direct identification of occupants and inference of host ...

The Experiences of Women With Polycystic Ovary Syndrome of the Healthcare They Receive: A Qualitative Systematic Review

open access: yesJournal of Advanced Nursing, EarlyView.
ABSTRACT Background More than 12% of women worldwide are affected by polycystic ovary syndrome (PCOS), whose symptoms are similar to those of puberty, often leading to delayed diagnosis and missing the opportunity for early intervention. This not only puts PCOS women under physical and mental stress but also reduces their trust in doctors and makes ...

Exploration of Limonium interspecific breeding possibility : a thesis presented in partial fulfilment of the requirement for the degree of Master of Science in Plant Science at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 1995
Interspecific crossability was investigated in the genus Limonium (Plumbaginaceae). Six Limonium species were chosen for this study, five of which are dimorphic and L.perigrinum which is monomorphic.

Is Nocturnal Pollination Important for Crop Production? Experimental Evidence From Small Fruit Crops

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Insect‐mediated pollination is essential for crop production but is mainly studied considering diurnal pollinators only. Here, we use pollinator exclusion techniques to prevent either diurnal or nocturnal insect visits in small fruit crops: raspberry (Rubus idaeus), over 1 year, and red currant (Ribes rubrum) and black currant (Ribes nigrum ...
