Tetraploids, triploids, and 2n pollen from diploid interspecific crosses with cassava
Theoretical and Applied Genetics, 1990 Interspecific crosses of five cultivated cassava varieties (2n=36) were made with two related Manihot species, M. epruinosa (2n=36) and M. glaziovii (2n=36). From these diploid interspecific crosses, four spontaneous tetraploids (2n=4x=72) and two triploids (2n=3x=54) were isolated for the first time in cassava.

Colchicine did not affect the viability of induced 2n pollen in Populus tomentosa
Silva Fennica, 2019 Colchicine is widely used as a mutagen to induce production of diploid gametes in plants. However, whether colchicine affects induced pollen viability remains unclear.

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 ...

Genetics and Molecular Biology, 2006 The cultivated and sexually compatible species Pennisetum purpureum (elephant grass, 2n = 4x = 28) and Pennisetum glaucum (pearl millet, 2n = 2x = 14) can undergo hybridization which favors the amplification of their genetic background and the ...

American Journal of Botany, EarlyView.Abstract Premise Insect herbivory is a major biotic factor shaping plant populations and driving the evolution of defensive traits. Polyploidy (whole‐genome duplication) often induces substantial phenotypic and genotypic changes that may affect species interactions, including herbivory.

Land Degradation &Development, EarlyView.ABSTRACT This study presents an innovative assessment model for analyzing the evolution of degraded soils subjected to different reclamation strategies. The proposal combines statistical and artificial intelligence tools to jointly integrate multiple physical and chemical soil properties, allowing for a more synthetic view of the processes.

Wheat breeding approaches for designing wheat to thrive in a warmer world
PLANTS, PEOPLE, PLANET, EarlyView.Wheat is a vital food crop, accounting for approximately 20% of daily calories and protein consumed worldwide. However, modern‐day wheat is under pressure from global change. The improvement rate of wheat yields is not keeping up with the demand of our growing population. Furthermore, abiotic and biotic stressors are becoming more prevalent. This paper

CENH3-GFP: a visual marker for gametophytic and somatic ploidy determination in Arabidopsis thaliana [PDF]
, 2016 Background: The in vivo determination of the cell-specific chromosome number provides a valuable tool in several aspects of plant research. However, current techniques to determine the endosystemic ploidy level do not allow non-destructive, cell-specific
