Green Algae01:21

Green Algae

Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...
Other Algae01:19

Other Algae

The group Stramenopiles include some phototrophic microorganisms. Members of this group possess flagella covered in numerous short, hairlike extensions, a feature that inspired the group's name, derived from the Latin words for "straw" and "hair." Some of the main categories of Stramenopiles include diatoms, golden algae, and brown algae.Diatoms are unicellular, photosynthetic eukaryotes, with over 200 known genera. They play a key role in the planktonic communities of both marine and...
Red Algae01:23

Red Algae

Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...
Overview of Algae01:28

Overview of Algae

The kingdom Archaeplastida encompasses red and green algae, along with land plants. Unlike other protists with chloroplasts that arose through secondary endosymbiosis, only red and green algae originated from primary endosymbiotic events. This diverse group of eukaryotic organisms contains chlorophyll and performs oxygenic photosynthesis.Algae exist in various forms, from large brown kelp in coastal waters to green scum in puddles and stains on rocks or soil. Some species are responsible for...
Microbial Mats01:25

Microbial Mats

Microbial communities forming biofilms and mats represent complex, spatially structured ecosystems where metabolic processes are stratified according to light, oxygen, and nutrient gradients. Biofilms are initial colonization stages, only a few millimeters thick, while mature microbial mats can reach centimeter-scale thickness and display intricate vertical organization. Their structural and functional heterogeneity allows microorganisms to occupy distinct ecological niches within a few...
Deep Sea Microbial Ecology01:18

Deep Sea Microbial Ecology

The deep ocean and its underlying sediments represent vast, largely unexplored microbial habitats that extend far beyond the sunlit photic zone. The photic (euphotic) zone typically spans the upper ~100–200 meters of pelagic waters in the open ocean, but its depth varies geographically and seasonally, where sufficient light supports photosynthetic life. Below this lies the deep sea, spanning roughly 1000–6000 meters (bathypelagic to abyssal zones), with deeper hadal trenches extending beyond...

Area of Science:

  • Environmental microbiology
  • Plant science
  • Biogeochemistry

Background:

  • Algae from the Viridiplantae lineage inhabit glaciers and snow patches globally.
  • These cryosphere algae are adapted to extreme conditions like freezing temperatures, high light, and oligotrophic environments.
  • The cellular nutrient balancing strategies of cryosphere algae remain largely unknown.

Purpose of the Study:

  • To investigate the single-cell ionomes of cryosphere chlorophyte algae.
  • To compare the ionomes of cryosphere algae with mesophile chlorophyte algae.
  • To understand nutrient homeostasis in algae adapted to extreme cold environments.

Main Methods:

  • Single-cell inductively coupled plasma-mass spectrometry (SC-ICP-MS) was used to quantify ionomes.
  • Cryosphere algae (Microglena sp., Raphidonema sempervirens, Deuterostichococcus sp.) and mesophile algae (Acutodesmus obliquus, Chlamydomonas reinhardtii) were analyzed.
  • Results were validated using mass spectrometric analyses of digested cultures.

Main Results:

  • Cryosphere algae showed lower single-cell Phosphorus, Magnesium, and Calcium per cell biovolume compared to mesophiles, suggesting slower metabolism.
  • Under phosphorus starvation, Raphidonema sempervirens maintained its ionome, while Microglena sp. showed a P and Mg loss and Cu increase, indicating polyphosphate hydrolysis.
  • Algal ionomes differ significantly between cryosphere and mesophile species.

Conclusions:

  • Cryosphere algae possess unique nutrient homeostasis mechanisms for survival in extreme cold.
  • Single-cell ionome analysis provides critical insights into algal adaptation to oligotrophic and freezing conditions.
  • Understanding cryosphere algal nutrient strategies is vital for predicting ecosystem responses to climate change.
