Transcriptome Analysis of Scrippsiella trochoidea CCMP 3099 Reveals Physiological Changes Related to Nitrate Depletion

FRONTIERS IN MICROBIOLOGY, 7.

By: J. Cooper *, G. Sinclair n & B. Wawrik *

author keywords: transcriptome; Scrippsiella trochoidea; harmful algae; nutrient limitation; nitrogen; dinoflagellates; phytoplankton; algal physiology
TL;DR: Surprisingly, the transcriptome also contained transcripts potentially related to secondary metabolite production, including a homolog to the Short Isoform Saxitoxin gene (sxtA) from Alexandrium fundyense, which was significantly up-regulated under N-depletion. (via Semantic Scholar)

2015 journal article

Deep-water seed populations for red tide blooms in the Gulf of Mexico

MARINE ECOLOGY PROGRESS SERIES, 529, 1–16.

By: L. Waters  n, T. Wolcott n, D. Kamykowski n & G. Sinclair n

author keywords: Harmful algal blooms; Benthic orientation; Karenia brevis; Nutrient limitation; Biomimetic; Lagrangian drifter
TL;DR: Measurements of nutrients and light from the water column in a potential bloom- forming region of the WFS were higher than the model-generated requirements for growth, suggesting that coastal nutrient distributions could support a coastal population offshore. (via Semantic Scholar)

2009 journal article

LIPID CLASS, CAROTENOID, AND TOXIN DYNAMICS OF KARENIA BREVIS (DINOPHYCEAE) DURING DIEL VERTICAL MIGRATION

JOURNAL OF PHYCOLOGY, 45(1), 154–163.

By: B. Schaeffer*, D. Kamykowski n, L. McKay n, G. Sinclair n & E. Milligan n

author keywords: behavior; brevetoxins; dinoflagellate; epoxidation state; lipids
TL;DR: K. brevis may mobilize its toxins into the surrounding environment by reducing lipid concentrations, such as sterols, limiting competition, or toxins are released because lipids are decreased in high light, reducing any protective mechanism against their own toxins. (via Semantic Scholar)

2007 journal article

A comparison of photoresponse among ten different Karenia brevis (Dinophyceae) isolates

JOURNAL OF PHYCOLOGY, 43(4), 702–714.

By: B. Schaeffer n, D. Kamykowski n, L. McKay n, G. Sinclair n & E. Milligan n

author keywords: carbon; cell division rate; culture; dinoflagellate; F-v/F-m; Karenia brevis; P-E curve; photoinhibition
TL;DR: PAM‐FL techniques used to investigate P–E curves, quantum yield of PSII (Fv/Fm), and chl from 10 K showed that K. brevis was more than capable of utilizing and surviving in light conditions that may be present on cloudless days off Florida. (via Semantic Scholar)

2006 journal article

Comparison of swimming speed and photophysiological responses to different external conditions among three Karenia brevis strains

HARMFUL ALGAE, 5(6), 623–636.

By: L. McKay n, D. Kamykowski n, E. Milligan n, B. Schaeffer n & G. Sinclair n

author keywords: behavior; dinoflagellate; intraspecies comparison; Karenia brevis
TL;DR: The results suggest that cells may partition energy selectively depending on the needs of the cell, and a generalized species response to light and temperature ranges. (via Semantic Scholar)

2006 journal article

Nitrate uptake by Karenia brevis. I. Influences of prior environmental exposure and biochemical state on diel uptake of nitrate

MARINE ECOLOGY PROGRESS SERIES, 328, 117–124.

By: G. Sinclair n, D. Kamykowski n, E. Milligan n & B. Schaeffer n

author keywords: Karenia brevis; dinoflagellate; physiology; nocturnal uptake; vertical migration
TL;DR: Testing how the physiology of K. brevis contributed to the acquisition of nitrate by evaluating how nitrate uptake changed with prior environmental exposure found enhanced nocturnal uptake compared to cells continuously exposed to nitrate-replete conditions. (via Semantic Scholar)

2006 journal article

Nitrate uptake by Karenia brevis. II. Behavior and uptake physiology in a nitrate-depleted mesocosm with a bottom nutrient source

MARINE ECOLOGY PROGRESS SERIES, 328, 125–131.

By: G. Sinclair n, D. Kamykowski n, E. Milligan n & B. Schaeffer n

author keywords: Karenia brevis; dinoflagellate; physiology; nocturnal uptake; vertical migration; sediment
TL;DR: Both migration, as indicated by diel aggregation patterns, and cell physiology indicate that descent to regions of higher nutrient concentrations were sufficient to main- tain average growth rates of 0.3 div d -1 . (via Semantic Scholar)
