Past, present and future of local crop evolution

PLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

The pistil as a traffic light: Yellow‐to‐red color change likely influences pollinator visitation patterns in Saxifraga fortunei (Saxifragaceae)

PLANTS, PEOPLE, PLANET, EarlyView.
Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...

Increased utilitarian value of invasive species in regions with long invasion history may limit public engagement for invasion control

PLANTS, PEOPLE, PLANET, EarlyView.
Positive perceptions of invasive species can hinder effective management, especially if management efforts that are rooted in scientific theories are misaligned with local ecological knowledge. We documented local ecological knowledge about land invasibility as predicted by invasion biology theories. Participants with greater local ecological knowledge

Assessment of Genetic Variability for Yield and Yield Components in Rice (Oryza sativa L.) Germplasms

International Journal of Bio-Resource and Stress Management, 2018
Thirty eight rice germplasms were evaluated to assess their genetic variability, heritability, genetic advance, correlation and direct- indirect effect for grain yield and yield contributing traits.

Identification of the Parental Lines for Hybrid Rice Through a Three-Way Test Cross-System in Egypt [PDF]

Journal of Plant Production
A three-way test cross was employed to evaluate the genetic fertility restoration systems in hybrid rice and identify efficient restorers and maintainers. Ten elite diverse lines and cytoplasmic male sterile (CMS) lines from the WA source IR 69625 A were

Fonio (Digitaria exilis and Digitaria iburua) in Nigeria: Regional cultivation patterns, landrace diversity, and farmer knowledge for conserving a climate‐resilient indigenous cereal

PLANTS, PEOPLE, PLANET, EarlyView.
Fonio (Digitaria exilis and Digitaria iburua) cereals are valued for their drought resilience, adaptability to poor soils, and cultural importance. In Nigeria, where both species are cultivated, fonio has declined due to labor‐intensive processing, lower yields, and changing livelihood choices. By documenting 21 landraces (15 D. exilis and 6 D. iburua),

Identification of Effective Restorers and Maintainers for Development of Rice Hybrids in Temperate Ecology [PDF]

Electronic Journal of Plant Breeding, 2014
Three cytoplasmic male sterile (CMS) lines with Wild Abortive (WA) CMS source were crossed with 9 rice genotypes to assess their restorer/maintainer behavior during 2011-12.

Soybean plant architecture influences the capacity of Telenomus podisi to parasitize Euschistus heros eggs: implications for field releases

Pest Management Science, EarlyView.
Increasing soybean plant architectural complexity reduces the ability of Telenomus podisi to parasitize Euschistus heros eggs, highlighting the need to adjust parasitoid release rates in the field according to plant complexity (arrow direction and thickness correspond to the increasing strength of the variable) . Abstract BACKGROUND Plant architectural

Spikelet Proteomic Response to Combined Water Deficit and Heat Stress in Rice (Oryza sativa cv. N22) [PDF]

, 2014
In future climates, rice crops will be frequently exposed to water deficit and heat stress at the most sensitive flowering stage, causing spikelet sterility and yield losses.

Genetics, fertility behaviour and molecular marker analysis of a new TGMS line, TS6, in rice [PDF]

, 2004
The thermosensitive genic male sterility (TGMS) system has great potential for revolutionizing hybrid rice production through simple, less expensive and more efficient seed production technology.
