The Evolution of Self-Fertilization in Density-Regulated Populations [PDF]
We study the evolution of selfing in hermaphrodites to reveal the demographic conditions that lead to intermediate selfing rates. Using a demographic model based on Ricker-type density regulation we first assume that independent of population density ...

DNA amplified fingerprinting, a useful tool for determination of genetic origin and diversity analysis in Citrus [PDF]
We used three short repetitive nucleotide sequences [(GTG)5, (TAC)5, and (GACA)4] either as radiolabeled probes for hybridization with restricted Citrus DNA or as single primers in polymerase chain reaction amplification experiments with total genomic ...

Self-fertility in Pseudomonas aeruginosa [PDF]
SUMMARY: Two interfertile strains of Pseudomonas aeruginosa were re-examined for evidence of self-fertility. One strain was self-fertile, the frequency of recombination being affected by the manner in which the parent organisms were grown before being combined. The other strain gave no evidence of self-fertility.

Reproductive success through high pollinator visitation rates despite self incompatibility in an endangered wallflower [PDF]
PREMISE OF THE STUDY: Self incompatibility (SI) in rare plants presents a unique challenge—SI protects plants from inbreeding depression, but requires a sufficient number of mates and xenogamous pollination. Does SI persist in an endangered polyploid? Is

Plant Mating Systems Often Vary Widely Among Populations
Most flowering plants are hermaphroditic, yet the proportion of seeds fertilized by self and outcross pollen varies widely among species, ranging from predominant self-fertilization to exclusive outcrossing.

The scale of population structure in Arabidopsis thaliana [PDF]
The population structure of an organism reflects its evolutionary history and influences its evolutionary trajectory. It constrains the combination of genetic diversity and reveals patterns of past gene flow.

Connection of fertilization conditions of sour cherry and meteorological parameters
Our analyses showed that the degree of free fertilization is mostly influenced by maximum temperature and sunshine duration.We found that free fertilization ratio increases with higher daily maximum temperatures; similar results characterise sunshine ...

Deciphering the genome structure and paleohistory of _Theobroma cacao_ [PDF]
We sequenced and assembled the genome of _Theobroma cacao_, an economically important tropical fruit tree crop that is the source of chocolate. The assembly corresponds to 76% of the estimated genome size and contains almost all previously described ...

Analysis of self-fertilization and meiotic behavior of eleven Brazilian triticale cultivars at two sowing dates [PDF]
Eleven Brazilian hexaploid triticale cultivars (2n = 6x = 42), from three breeding programs, were evaluated for theirability of self-fertilization in 2006 and for meiotic behavior, meiotic index and pollen viability at two sowing dates in 2007 ...

Mixed Mating System Are Regulated by Fecundity in Shorea curtisii (Dipterocarpaceae) as Revealed by Comparison under Different Pollen Limited Conditions. [PDF]
The maintenance of mixed mating was studied in Shorea curtisii, a dominant and widely distributed dipterocarp species in Southeast Asia. Paternity and hierarchical Bayesian analyses were used to estimate the parameters of pollen dispersal kernel, male ...
