ZSL Orchestrates Synaptonemal Complex Assembly as a Central Region Scaffold to Ensure Synapsis Fidelity and Crossover Control in Polyploid Meiosis

Advanced Science, EarlyView.
A central molecular adaptor, ZSL, is identified that links transverse filaments ZYP1 to central element SCEP1/2 to drive synaptonemal complex assembly in Brassica napus. Loss of ZSL abolishes synaptonemal complex formation, disrupts meiotic chromosome segregation, and markedly increases crossovers, providing mechanistic insight into meiotic fidelity ...

Pollen Collected and Foraging Activities of Frieseomelitta varia (Lepeletier) (Hymenoptera: Apidae) in an Urban Landscape

Sociobiology, 2013
Cities provide resources for animal species that live within them or inhabit their surroundings. This has motivated an increase in ecological studies of urban areas, including the interactions between plants and pollinators.

Detection of Airborne Allegen Phl p5 and its Correlation with Poaceae Pollen Counts in Evora, South Portugal [PDF]

, 2008
Introduction: Airborne pollen of grasses (Poaceae family) is the main aeroallergen in many european countries, namely in Portugal. Their pollen can be found in the air all over the year but higher concentrations are reached in springtime (Mars to June ...

Preliminary characterization of a Moroccan honey with a predominance of Bupleurum spinosum pollen [PDF]

, 2017
Honey with Bupleurum spinosum (zandaz) as a main pollen source has not been the subject of previous detailed study. Therefore, twelve Moroccan samples of this honey were subjected to melissopalynological, physicochemical and microbiological quality ...

Additive and Partially Dominant Effects from Genomic Variation Contribute to Rice Heterosis

Advanced Science, EarlyView.
Additive and partially dominant effects, namely at mid‐parent levels or values between mid‐parent and parental levels, respectively, are the predominant inheritance patterns of heterosis‐associated molecules. These two genetic effects contribute to heterosis of agronomic traits in both rice and maize, as well as biomass heterosis in Arabidopsis ...

Maize Anther Development Involves Translated Open Reading Frames From 3′ Untranslated Regions

Advanced Science, EarlyView.
This study examined the translation activity across ten stages of maize anther development, integrating transcriptome and small‐peptide data. It linked mutations in translated 3' ORFs to anther sterility, exemplified by Zm00001eb417050_3' ORF (known as APV1). In addition, the data indicated that maize anthers could assimilate CO2 through the stomata in

The restoration of ecological interactions: plant-pollinator networks on ancient and restored heathlands [PDF]

, 2008
1. Attempts to restore damaged ecosystems usually emphasize structural aspects of biodiversity, such as species richness and abundance. An alternative is to emphasize functional aspects, such as patterns of interaction between species.
