Floral traits influencing outcrossing rate in rice

, 1997
This article 'Floral traits influencing outcrossing rate in rice' appeared in the International Rice Research Notes series, created by the International Rice Research Institute (IRRI) to expedite communication among scientists concerned with the development of improved technology for rice and rice-based systems.

Does anthocyanin affect outcrossing rates in Datura Stramonium (Solanaceae)? [PDF]

American Journal of Botany, 2000
In this paper, I investigate whether the presence or absence of anthocyanin is neutral with respect to reproduction in Datura stramonium. The observations concern the portion of the life cycle spanning pollination to germination. Pollinators do not appear to distinguish between floral morphs, as revealed by nonbiased distribution of fluorescent powder ...

Outcrossing rates in the gynomonoecious‐gynodioecious species Dianthus sylvestris (Caryophyllaceae) [PDF]

American Journal of Botany, 2003
Some species described as gynodioecious are truly gynomonoecious‐gynodioecious. Three distinct phenotypes may be found in their natural populations—female and hermaphrodite pure‐sexed plants bearing either only pistillate or perfect flowers, respectively, and mixed plants bearing both types of flowers.

Genome-wide association study of outcrossing in cytoplasmic male sterile lines of rice

Scientific Reports, 2017
Stigma exsertion and panicle enclosure of male sterile lines are two key determinants of outcrossing in hybrid rice seed production. Based on 43,394 single nucleotide polymorphism markers, 217 cytoplasmic male sterile lines were assigned into two ...

Rate of Adaptation in Large Sexual Populations

, 2010
Adaptation often involves the acquisition of a large number of genomic changes which arise as mutations in single individuals. In asexual populations, combinations of mutations can fix only when they arise in the same lineage, but for populations in ...

Outcrossing rate and inbreeding depression in the herbaceous autotetraploid, Campanula americana [PDF]

Heredity, 2003
Polyploidy in angiosperms is frequently associated with an increase in self-compatibility. Self-fertilization can enhance polyploid establishment, and theory predicts reduced inbreeding depression in polyploids relative to diploids. Therefore, we may expect mating systems that promote self-fertilization or mixed-mating in polyploid species.

Versatile CRISPR‐Cas Tools for Gene Regulation in Zebrafish via an Enhanced Q Binary System

Advanced Science, EarlyView.
This study introduces CRISPR‐Q, a transgenic CRISPR‐Cas system leveraging the QFvpr/QUAS binary expression platform in zebrafish. CRISPR‐Q overcomes previous challenges in achieving stable and efficient gene regulation. By enabling precise spatiotemporal control of transcript knockdown (CRISPR‐QKD) and gene activation (CRISPR‐Qa), it provides a ...

Studies on reproductive strategies of Vitex negundo L. var. heterophylla (Franch.) Rehder (Lamiaceae) based on morphological characteristics and SSR markers

Ecology and Evolution, 2020
Vitex negundo L. var. heterophylla (Franch.) Rehder (Lamiaceae) is an important tree species for soil and water conservation, yet the reproductive ecology of this species remains to be elucidated. To investigate the reproductive traits of V. negundo var.

Outcrossing rates of marked poisson cluster processes in structural reliability

Applied Mathematical Modelling, 1988
A marked Poisson cluster process (PCP) is defined as a model for live loads in buildings. The outcrossing rate for this PCP and the superposition of such processes are derived for the determination of structural failure probabilities. For the equilibrium process a Poisson limit theorem for the failure probability and an asymptotic approximation for the

Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen‐rewarding Caribbean bloodwort

American Journal of Botany, EarlyView.
Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in
