In Vitro Culture of Pogostemon Cablin Benth. (Nilam Plant): the Effect of Naa and Bap on Embryogenic Callus Proliferation and Subsequent Somatic Embryogenesis

open access: yesMakara Seri Sains, 2004
An experiment to investigate the somatic embryogenesis from shoot-derived callus of Pogostemon cablin (nilam plant) has been conducted at the Plant Biotechnology Laboratory, Agricultural Faculty, University of Jambi from January through to July 2004 ...

High auxin stimulates callus through SDG8‐mediated histone H3K36 methylation in Arabidopsis

open access: yesJournal of Integrative Plant Biology, Volume 64, Issue 12, Page 2425-2437, December 2022., 2022
Callus induction, which results in cell fate transition, is considered as first and key step for plant regeneration. During the process, high auxin activates SET DOMAIN GROUP8 (SDG8) expression through TIR1/AFB‐based transcriptional regulation. SDG8 then deposits H3K36me3 modifications on the loci of callus‐related and cell proliferation‐related genes,

Automated extraction of right whale morphometric data from drone aerial photographs

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Aerial photogrammetry is a popular non‐invasive method for measuring marine mammal body size, body morphometrics, and body condition, but processing large datasets efficiently remains challenging. We developed a machine learning algorithm using Mask R‐CNN models to automatically measure body morphometrics of southern right whales from aerial ...

The Emotional Valence of Hyperrationality in STEM Learning: Reinscriptions and Contestations of Coloniality

open access: yesScience Education, EarlyView.
ABSTRACT As part of the special issue Centering Affect and Emotion Toward Justice and Dignity in Science Education, this paper examines the emergence and performance of hyperrationality in STEM classrooms. Hyperrationality describes verbal and embodied expressions whereby learners try to maintain an appearance of neutrality and emotional distance to ...

The Enhancement of Catharanthine Content in Catharanthus roseus Callus Culture Treated with Naphtalene Acetic Acid

open access: yesHayati Journal of Biosciences, 2006
The research aim was to examine the enhancement of catharanthine content in Catharanthus roseus callus culture added with different concentration of Naphtalene Acetic Acid (NAA). NAA treatment produced callus that formed hairy roots. Fresh and dry weight

An Arabidopsis Cell Culture With Weak Circadian Rhythms Under Constant Light Compared With Constant Dark Can Be Rescued by ELF3

open access: yesPlant Direct
Callus and cell suspension culture techniques are valuable tools in plant biotechnology and are widely used in fundamental and applied research. For studies in callus and cell suspension cultures to be relevant, it is essential to know if the underlying ...

Climate‐induced upslope shift of orthopteran herbivores imposes greater herbivory through trait complementarity

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The asynchronous upward shift of insect herbivores and plants towards higher elevations following climate warming is anticipated to generate novel plant–insect interactions.
