Comparative gene mapping in Arabidopsis lyrata chromosomes 1 and 2 and the corresponding A. thaliana chromosome 1: recombination rates, rearrangements and centromere location [PDF]

, 2006
To add detail to the genetic map of Arabidopsis lyrata, and compare it with that of A. thaliana, we have developed many additional markers in the A. lyrata linkage groups, LG1 and LG2, corresponding to A. thaliana chromosome 1.

Population genomic signatures of founding events in autonomously self‐fertilizing plants: a test with Impatiens capensis

New Phytologist, EarlyView.
Summary Autonomously self‐fertilizing plants possess disproportionate abilities to found populations. Viewed from the metapopulation perspective, founding events should be frequent in such plants, but the intensity and timing of bottlenecks and recovery should vary among populations.

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.

New Phytologist, EarlyView.
Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

Pollen Dispersal and Pollination Patterns Studies in Pati Kopyor Coconut using Molecular Markers

CORD, 2015
Parentage analysis has been used to evaluate pollen dispersal in Kopyor coconut (Cocos nucifera L.). Investigations were undertaken to elucidate (i) the dispersal of pollen, (ii) the rate of self and out-crossing pollination, and (iii) the distance of ...

031 Rate of Natural Outcrossing in Cucumber Isolation Blocks [PDF]

HortScience, 1999
Cucumber (Cucumis sativus L.) populations often are intercrossed after each selection cycle using bees in isolation blocks. Previous research showed the rate of natural outcrossing in monoecious cucumber inbreds was 36%. The objective of this experiment was to determine whether the rate of natural outcrossing could be increased using hormones, plot ...

Recombination suppression in plant adaptation and speciation

New Phytologist, EarlyView.
Summary Recombination suppression is increasingly recognized as an important facilitator of genomic divergence and speciation, especially under ongoing gene flow. In plants, however, the broader evolutionary consequences and the mechanisms by which recombination suppression arises and spreads are still incompletely understood, reflecting the inherent ...

Levels of diversity and inbreeding in a clonal seed orchard for high-mountain ecotype of Scots Pine [PDF]

Silva Balcanica
Seed orchards are an important source of high-quality seeds for afforestation. Genetic composition of seed orchard crop was studied in a clonal seed orchard situated in Borovets, Rila Mts, which was designed for producing seed for high-mountain ...

Gametocyte sex ratios as indirect measures of outcrossing rates in malaria

Parasitology, 1992
The frequency of recombination between unlike genotypes is central to understanding the generation of genetic diversity in natural populations of malaria. Here we suggest a way of investigating the problem which could complement conventional biochemical approaches to the population genetics of malaria.

Removal of Transgenes and Evaluation of Yield Penalties in Genome Edited Bacterial Blight Resistant Rice Varieties

Plant Biotechnology Journal, EarlyView.
ABSTRACT Bacterial blight (BB) of rice, caused by Xanthomonas oryzae pv. oryzae (Xoo), is one of the major drivers of yield losses in Africa and Asia. Xoo secretes TAL‐effectors (TALe) that induce host SWEET sucrose uniporter by binding to the effector binding element (EBE) of SWEET promoters, likely required for Xoo reproduction and virulence.

Genetic evaluation of seeds of highly endangered Pinus uliginosa Neumann from Węgliniec reserve for ex-situ conservation program

Acta Societatis Botanicorum Poloniae, 2011
Peat-bog pine Pinus uliginosa Neumann has become extinct or rare in many parts of Europe. We have investigated the levels of genetic variation and inbreeding in seeds collected from a highly endangered reserve of this species in Poland, using allozymes ...
