Plant extracts and their components have been reported to have antimicrobial properties against phytopathogens. Although such properties could be harnessed for the development of new pathogen control strategies, there are no standardised methods for their assessment in different extracts. The laboratory exercise presented here involves the use of…

Wheat powdery mildew is an important fungal pathogen of wheat with an obligatory biotrophic lifestyle (a parasite that can only develop on a living host). We investigated the genetics of this host-pathogen interaction by using phenotyping and PCR assays to detect genes in both wheat and powdery mildew, which are known determinants of the outcome…

The mastery of the ability to identify and describe plant morphology is an essential aspect of studying biology. The skill of describing plants can be developed through diverse learning resources, including textbooks and contextual materials. Therefore, this study aims to determine students' ability to describe the morphology of plants using a…

The yellow-blue color pair has been used in creative artwork such as paintings and designs and in color engineering. Herein we present a method for using the yellow-blue combination in a chemistry lesson dealing with [pi]-conjugated molecules for first-year undergraduate students who are not science majors. The lesson begins with an introduction…

An undergraduate laboratory experiment has been developed for the synthesis of a reactive cross-linker that is useful in various highly visual demonstrations of organic reactivity, click chemistry, and biobased polymer synthesis. A triazolinedione-based cross-linker, which is known as a useful reagent for click chemistry, can be obtained from…

Triterpenic acids (TA), a class of triterpenoids, are widely distributed as secondary metabolites in plants. They have a pentacyclic structure and show high structural diversity. In this work, a simple but efficient method for extraction and detection of TA derivatives from apple peels is described. The method is technically straightforward and…

Antioxidants are molecules that act against free radicals, and this effect can bring many benefits to health and society. Antioxidants can be found in various matrices of nature, such as fruits and plants. Some studies have shown that "Rhizophora mangle," a typical mangrove plant, is rich in antioxidants. People report its use for…

A new organic chemistry experiment aimed to separate the chlorophyll precursor in plant seeds by column chromatography is described. The primary pedagogical goal in developing this experiment is to establish a simple and interesting chromatographic separation to demonstrate basic concepts and the standard procedure for this important lab…

This paper describes the master course design process at the largest institution of higher education in Colorado, USA. The master course design process demonstrated principles of backwards design and employed a team-based approach to course development. The course map was the primary vehicle for communicating the design of the course during…

Course-based undergraduate research experiences (CUREs) provide students with valuable opportunities to engage in research in a classroom setting, expanding access to research opportunities for undergraduates, fostering inclusive research and learning environments, and bridging the gap between the research and education communities. While…

Raman scattering spectroscopies are important analytical tools in modern chemistry. Here, we describe the construction of the unamplified Raman scattering analysis (URSA) instrument: an inexpensive, open-table Raman spectrometer that uses a 532 nm diode-pumped laser as a light source. Upon application of this spectrometer to DNA extracted from…

In the past few decades, chemistry has evolved to interact with various disciplines to synergistically help tackle global challenges. This, in turn, requires that newer generations of chemistry students are trained to be more flexible in accepting and coordinating new concepts. In this experiment, pineapple was used as a key model to allow for the…

The chemical experiment is designed for undergraduates majoring in chemistry, energy, and environment. The intended purpose is that the students will comprehend the reaction mechanism of photocatalytic reduction of CO[subscript 2] through hands-on experiments and deepen their understanding of sustainable energy technologies. More importantly, the…

The CRISPR/Cas9 system is widely used for editing genes in various organisms and is a very useful tool due to its versatility, simplicity, and efficiency. To teach its principles to post-graduate students we designed a laboratory activity to obtain and analyze PDS3 mutants in "Arabidopsis thaliana" plants consisting of: 1) Design of…

Many ferns learning in higher education were organized conventionally and relied only on textbooks. Moreover, it is not in accordance with the characteristics or learning styles of Generation Z (Gen Z). This research aims to produce Pteridophyte Smart Cards (PSC) as a learning media by integrating cards containing real images of ferns with QR Code…
