Fungitoxicity in pollen grains [PDF]

Grana, 1983
Abstract While screening 45 samples of pollen suspension for their antifungal activity against Helminthosporium oryzae and Alternaria alternata, only that of Lycopersicon lycopersicum exhibited absolute toxicity against both the pathogens. The maximum inhibitory dilutions were found to be 1: 200 and 1: 500 (w/v) against A. alternata and H.

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 ...
