Chromosome arm length, and a species-specific determinant, define chromosome arm width [S. pombe]

Project description:Mitotic chromosomes in different organisms adopt various dimensions. What defines chromosome dimensions is scarcely understood. Here, we compare budding and fission yeasts that harbor similarly sized genomes distributed amongst 16 or 3 chromosomes, respectively. Budding yeast chromosomes are thinner and characterized by shorter mitotic chromatin interactions. This remains the case even following chromosome fusions to form three fission-yeast-length entities, revealing a species-specific organizing principle that correlates with condensin binding site spacing. Unexpectedly, within each species, longer chromosome arms are always thicker, a trend also observed with human chromosomes. Arm length as a chromosome width determinant informs mitotic chromosome formation models.

A Y-chromosome-encoded small RNA acts as sex determinant in persimmons

Project description:In plants, multiple lineages have evolved sex chromosomes independently, providing a powerful comparative framework, but few specific determinants controlling the expression of a specific sex have been identified. We investigated sex-determinants in Caucasian persimmon, Diospyros lotus, a dioecious plant with heterogametic males (XY). Male-specific short nucleotide sequences were used to define a male determining region. A combination of transcriptomics and evolutionary approaches detected a Y-specific sex-determinant candidate, OGI, that displays male-specific conservation among Diospyros species. OGI encodes a small RNA targeting the autosomal MeGI gene, a homeodomain transcription factor regulating anther fertility in dosage-dependent fashion. This identification of a feminizing gene suppressed by a Y-chromosome-encoded small RNA contributes to our understanding of the evolution of sex chromosome systems in higher plants. For expression analyses, mixed buds were sampled on June 17, and July 4, 2013, corresponding to the early differentiation stages of male/female primordia, respectively.

The RHW1-ZCN4 regulatory pathway confers natural variation of husk leaf width in maize

Project description:Maize husk leaf - the outer leafy layers covering the ear - modulates kernel yield and quality. Despite its importance, however, the genetic controls underlying husk leaf development remain elusive. Our previous genome-wide association study identified a single nucleotide polymorphism located in the gene RHW1 (Regulator of Husk leaf Width) that is significantly associated with husk leaf-width diversity in maize. Here, we further demonstrate that a polymorphic 18-bp InDel (insertion/deletion) variant in the 3' untranslated region of RHW1 alters its protein abundance and accounts for husk leaf width variation. RHW1 encodes a putative MYB-like transcriptional repressor. Disruption of RHW1 altered cell proliferation and resulted in a narrower husk leaf, whereas RHW1 overexpression yielded a wider husk leaf. RHW1 positively regulated the expression of ZCN4, a well-known TFL1-like protein involved in maize ear development. Dysfunction of ZCN4 reduced husk leaf width even in the context of RHW1 overexpression. The InDel variant in RHW1 is subject to selection and is associated with maize husk leaf adaption from tropical to temperate regions. Overall, our results identify that RHW1-ZCN4 regulates a pathway conferring husk leaf width variation at a very early stage of husk leaf development in maize.
