マコンブの光合成における光の波長利用特性

3月に修士課程を修了した卒業生がマコンブの光合成における光の波長利用特性に関する論文をこのほど刊行しました。

マコンブは水深2〜15mでの漸深帯に生育しますが,クロロフィルaが光合成に利用する赤い波長の光はこの水深帯に十分に到達しません。本種の光合成を青,緑,赤色光のLEDと白色光(メタルハライドランプ:太陽光の波長構成に類似)で測定したところ,青い光のみで白色光と同等以上に光合成することが明らかになりました。マコンブが含有するフコキサンチンは,青色光に吸収スペクトルのピークがあることが知られていますが,このような補助色素が青色光のみの環境下で効率よく機能し,光合成をおこなっているものと考えられます。
本論文は,2022年7月4日付けのAlgal Research(IF=5.276)オンライン版で刊行されました。

New article: A brownalga, Saccharina japonica can be well photosynthesized under the subtidal blue-light environment.

 Please take a look at our new article featuring the interactive effects of temperature and irradiance including spectral light quality on the photosynthesis of a brown alga Saccharina japonica (Laminariales) from Hokkaido, Japan. This alga is known to be found in subtidal waters up to 20m deep in Hokkaido Island. As the red light that is essential to chlorophyll-a photosynthesis is quickly absorbed in shallow waters, the light spectral availability for photosynthesis is limited in such depth. In fact, the result of the present study revealed that this alga can be well photosynthesized under blue light that penetrates into subtidal waters.

T/S Nansei-Maru Tokara Islands Survey: Gaja-jima Island

 As the second research voyage of the T/S Nansei-Maru for our lab in May, we conducted the Tokara Islands survey featuring an uninhabited island, Gaja-jima island, northern Ryukyu Archipelago. This is the collaboration survey of the Marine Ecology, Ichthyology, and Marine Botany labs at Kagoshima University.
