Effects of Antimitotic Agents, Temperature and Immersion Time on Chromosome Doubling Efficiency in Supersweet Corn (Zea mays L. var. saccharata)

open access: yesPlant Breeding, EarlyView.
ABSTRACT Doubled haploid technology accelerates the development of fully homozygous maize lines compared with conventional selfing. However, specific protocols for supersweet corn (Zea mays L. var. saccharata), particularly regarding immersion time in antimitotic solutions and temperature during chromosome doubling, remain poorly defined.

Modulation of Anaphase‐Promoting Complex Genes Regulates Root‐Knot Nematode Gall Development and Plant Susceptibility

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT The anaphase‐promoting complex/cyclosome (APC/C) is a multi‐subunit E3 ubiquitin ligase that regulates cell cycle progression, but its role in plant‐pathogen interactions is poorly understood. Here, we demonstrate that regulation of the ubiquitin–proteasome system, involving APC/C‐associated components, is critical for coordinating host cell ...

More Science Than Art: The First Botanical Garden in Portugal (c. 1650)

open access: yesRenaissance Studies, EarlyView.
ABSTRACT Gabriel Grisley, a German physician, came to Portugal and founded a garden near the Xabregas River in Lisbon, during the 1610s under the Spanish kings' rule. In view of the utility a botanic garden represented for the kingdom, he was able to obtain a royal privilege from King João IV during the Restauration War against the Spanish (1640–1668).
