In opposition to the mother tongue hypothesis, the father tongue hypothesis states that humans tend to speak their fathers’ language, based on a stronger correlation of languages to paternal lineages(Y-chromosome) than to maternal lineages(mitochondria). To reassess these two competing hypotheses,we conducted a genetic–linguistic study of 34 modern Indo-European(IE) populations. In this study,genetic histories of paternal and maternal migrations in these IE populations were elucidated using phylogenetic networks of Y-chromosomal and mitochondrial DNA haplogroups, respectively. Unlike previous studies, we quantitatively characterized the languages based on lexical and phonemic systems separately. We showed that genetic and linguistic distances are significantly correlated with each other and that both are correlated with geographical distances among these populations. However, when controlling for geographical factors, only the correlation between the distances of paternal and lexical characteristics,and between those of maternal and phonemic characteristics, remained. These unbalanced correlations reconciled the two seemingly conflicting hypotheses.

The idea of assembling a Special Issue on Pollen Tube and Reproduction in Molecular Plant was conceived during the organization of the 2012 Pollen Biology International Symposium and Workshop held at the Shanghai Institute of Plant Physiology and Ecology （SIPPE）, Chinese Academy of Science （CAS）, 27-31 October 2012. Wei-Hua Tang of the SIPPE led the organization, with the support of Hong-Wei Xue, Director of SIPPE acting as Chair of the Organization committee. The 2-d symposium was attended by about 100 international participants and focused on reports and discus- sions on the most recent research activities in the field. The 2-d workshop that followed provided a forum for in-depth introduction on various aspects of pollen and plant reproduc- tion biology to about 200 graduate students, postdoctoral fellows, and new investigators to the field.

Objective: Rubicon is an inhibitory interacting protein of the autophagy-related protein Uvrag. We previously showed thatRubicon deficiency promotes autophagic fluxin vivo and that autophagy can degrade lipid droplets. This study aimed to investigate the effects of Rubicon deficiency on fasting-induced hepatic ***: Two-month-old wild-type (WT) andRubicon-deficient mice were subjected to feeding or fasting for 24 hours to induce hepatic steatosis. The distribution of liver lipid droplets was revealed by oil red O staining. Hepatic and plasma triglyceride, non-esterified fatty acid (NEFA), and cholesterol levels were detected using commercially available kits. Real-time reverse transcriptasepolymerase chain reaction was performed to analyze the mRNA expression of genes related to lipid metabolism in the liver. Western blot was conducted to assess autophagy-related protein levels in the liver. The animal experiments were approved by the Institutional Animal Care and Use committee at Shanghai Jiao Tong University, ***: We showed that under fasting conditions,Rubicon-deficient mice had more lipid droplets in the liver than WT controls. Consistent with these results, the hepatic triglyceride, NEFA, and cholesterol levels in fastedRubicon-deficient mice were significantly higher than those of fasted WT controls. The levels ofSREBP-1, a key regulator of lipid synthesis, were significantly lower in livers from fasted WT mice than those of fed WT mice. However, the decrease inSREBP-1 in fasted mice was attenuated byRubicon deficiency. Western blot analysis demonstrated that the fasting-induced increase in autophagic flux was amplified byRubicon deficiency. Finally, we showed thatRubicon deficiency in mice led to elevated plasma triglyceride and NEFA acid levels under fasting ***: Rubicon deficiency exacerbates fasting-induced hepatic steatosis in mice.
