The genetic basis of size variation in the reproductive organs of tomatillo (Physalis philadelphica) is unknown. Here we report that the expression levels of the gene Physalis Organ Size 1 (POS1) are positively associated with size variation in P. philadelphica reproductive organs such flowers, berries and seeds. POS1 knockdown results in smaller flowers and berries with smaller cells as compar...

The new Infectious Disease Prevention Law lists the following 5 diseases as those transmitted through sexual acts: syphilis, gonorrhea, Chlamydia infection of reproductive organs, herpes genitalis, and condyloma acuminatum. Among these, Chlamydia infection of reproductive organs and gonorrhea are likely to affect a woman’s reproductive capacity. The former in particular, which far surpasses the...

Guanylyl cyclase B is the receptor for a small peptide (C-type natriuretic peptide) produced locally in many different tissues. To unravel the functions of the receptor, we generated mice lacking guanylyl cyclase B through gene targeting. Expression of the receptor mRNA in tissues such as bone and female reproductive organs was evident, and significant phenotypes associated with each of these t...
