Development of a handheld chlorophyll content detector on wheat and maize leaves based on RGB sensor

open access: yesFrontiers in Plant Science
Chlorophyll-a (CL-a) and chlorophyll-b (CL-b) are major chlorophyll found in green plants. Determining the CL-a, CL-b, and total chlorophyll (TCL) contents is important to guide crop growth.

Effects of Different Prolonged Light Durations on Survival, Growth and Physiology of the Eelgrass Zostera marina

open access: yesFrontiers in Environmental Science, 2022
Prolongation of light duration is one of the effective methods to improve the current seagrass propagation technique. We subjected plants of eelgrass Zostera marina to different prolonged light durations [0 (control), 2, 4, 6, 8 h d−1] for 6 weeks under ...

Planning for the future, algae bloom dynamics in water management and ecosystem restoration efforts

open access: yesFrontiers in Water
Eutrophication and chronic harmful algal blooms (HABs) are a challenge for ecosystem managers and restoration planners. Drivers of HABs include nutrient availability, temperature patterns, atmospheric conditions, rainfall-runoff relationships, and lake ...

The concentration-independent effect of arbuscular mycorrhizal fungi on the tolerance of green foxtail to vanadium stress

open access: yesFrontiers in Plant Science
IntroductionArbuscular mycorrhizal fungi (AMF) show significant potential for improving plant tolerance to vanadium (V) stress. However, the pattern and physiological mechanisms behind this effect are not fully understood.MethodsTo investigate this, we ...

In Vitro Synthesis of Chlorophyll A in the Dark Triggers Accumulation of Chlorophyll A Apoproteins in Barley Etioplasts” [PDF]

open access: yes, 1990
An in vitro translation system using lysed etioplasts was developed to test if the accumulation of plastid-encoded chlorophyll a apoproteins is dependent on the de novo synthesis of chlorophyll a.
