Transcriptomic and lipidomic profiles reveal higher thermal adaptability in a tropical versus a temperate isolate of Chromera velia

Ayush Sharma, Aleš Tomčala, Tomáš Skalický, Dorsaf Ennaceur, Aleš Horák, Jitka Richtová, Vijaya Geetha Gonepogu, Jan R Šlapeta, Miroslav Obornı́k

This study compares transcriptomic and lipidomic responses of two Chromera velia isolates from different thermal environments to elevated temperatures, finding that the tropical isolate shows greater thermal adaptability.

Crystalline guanine packed within vacuoles serves as nitrogen store in Chromera velia

Vijaya Geetha Gonepogu, Jana Pilátová, Dorsaf Ennaceur, Aleš Tomčala, Marie Vancová, Jitka Richtová, Robyn A. Roth, Ursula W Goodenough, Miroslav Obornı́k, Peter Mojzeš, Ansgar Gruber

The paper investigates guanine crystal formation in Chromera velia under varying nitrogen conditions, finding that crystals store nitrogen within vacuoles and are composed of anhydrous guanine.
