Agrobacterium-mediated transient transformation of Flaveria bidentis leaves: a novel method to examine the evolution of C photosynthesis.
Plant Methods

School of Molecular Sciences, University of Western Australia, Crawley, WA, 6009, Australia.
The genus Flaveria has been studied extensively as a model for the evolution of C photosynthesis. Thus far, molecular analyses in this genus have been limited due to a dearth of genomic information and the lack of a rapid and efficient transformation protocol. Since their development, Agrobacterium-mediated transient transformation protocols have been instrumental in understanding many biological processes in a range of plant species.

Article Synopsis
- - Jaboticaba, a tropical plant that grows fruit on its trunks and branches, has been under-researched genomically, but this study created a gap-free reference genome and two nearly complete haploid genomes to enhance genomic resources.
- - The study also explored the evolutionary history of the Myrtaceae family, showing metabolic pathway expansions related to key processes like citric acid metabolism and biosynthesis of phenylpropanoids, which affect fruit characteristics.
- - Analysis of jaboticaba fruit skin color indicated that it's tied to specific biosynthesis pathways, particularly flavonoid production, and identified gene interactions that impact citric acid levels, suggesting directions for genetic improvements in jaboticaba.
Improvement of succinate production from methane by combining rational engineering and laboratory evolution in Methylomonas sp. DH-1.

While considerable knowledge exists about the enzymes pivotal for C photosynthesis, much less is known about the regulation important for specifying their expression in distinct cell types. Here, we use single-cell-indexed ATAC-seq to identify cell-type-specific accessible chromatin regions (ACRs) associated with C enzymes for five different grass species. This study spans four C species, covering three distinct photosynthetic subtypes: and (NADP-dependent malic enzyme), (NAD-dependent malic enzyme), (phosphoenolpyruvate carboxykinase), along with the C outgroup .

Phosphoenolpyruvate carboxylase (PEPC), as a necessary enzyme for higher plants to participate in photosynthesis, plays a key role in photosynthetic carbon metabolism and the stress response. However, the molecular biology of the family of Bambusoideae has been poorly studied, and the function of its members in the growth and development of Bambusoideae is still unclear. Here, we identified a total of 62 PEPC family members in bamboo.
