Yes, gelation is pH dependent. Adjusting the pH to 5.7 is recommended prior to heating to melt the agar and autoclaving to sterilize. Please see the link below to review the general plant culture medium preparation instructions available in the datasheet for product M5519 (formulation without agar):

Heterosis is the phenomenon whereby hybrid offspring of genetically divergent parents display superior characteristics compared with their parents. Although hybridity and polyploidy can influence heterosis in hybrid plants, the differential contributions of hybridity vs polyploidy to heterosis effects remain unknown.

Cytosine DNA methylation is an epigenetic regulatory system used by plants to control gene expression. Methylation pattern always changes after abiotic stresses, pathogens and pest infections or after a treatment with salicylic acid (SA). The latter is a key player

Dimethylation of histone H3 lysine 9 (H3K9me2) is a heterochromatic mark linked to DNA methylation and gene repression. Removal of H3K9me2 from gene bodies by the jmjC histone demethylase IBM1/JMJ25 inhibits DNA methylation and derepresses gene expression. In this work

What is the stability of the prepared Murashige and Skoog Basal Medium, Product M9274?
1 answer-
This agar-containing medium can be stored for 3 to 6 months, depending on the stability of any additional supplements, if stored properly with no observable dehydration of the gel. If the medium appears to darken or pull away from the sides of the culture vessel, it should be discarded.
