Summary: The liverwort Marchantia polymorpha is a crucial model plant for molecular evolution studies, with the capability to undergo genetic transformation using different stages of thalli. The establishment of mature thalli pre-cultivation method and young thalli direct co-culture method with stable transformation efficiency provides a more efficient approach for genetic manipulation in liverworts. The focus was mainly on reducing hands-on labor time for genetic transformation procedures.

Summary: Research has shown that peptide hormones MpCLE1 and MpCLE2 in Marchantia polymorpha play crucial roles in cell division and sexual reproduction by interacting with specific receptors at the apical meristem. Compared to other plants, Marchantia polymorpha possesses a minimal set of CLE family peptides, exhibiting higher conservation in evolutionary terms.

Summary: Genetic transformation in legume plants is an important area of agricultural research. Despite some progress in improving crop yields, challenges such as recalcitrance and genotype-dependence still exist. Future research may focus on overcoming these obstacles and further increasing yields.

Summary: The liverwort Marchantia polymorpha is an ideal model system for studying plant biology due to its streamlined genetics, experimental tractability, and morphological simplicity compared to vascular plants. The authors developed a transformation vector to produce a library of enhancer trap lines for Marchantia, allowing the identification and characterization of novel marker lines. This system revealed the presence of substructures within the apical notch and provided insights into sporeling development in Marchantia. The enhancer trap system is a valuable resource for future research on Marchantia.

Summary: Casuarina equisetifolia is widely used for agroforestry plantations for various purposes. This study established an efficient regeneration system using stem segment explants, optimizing callus induction and regeneration processes. Genetic transformation protocol using Agrobacterium tumefaciens was also optimized, leading to improved transformation efficiency to obtain transgenic plants in about 4 months. The findings will pave the way for further genetic manipulation and functional genomics of C. equisetifolia.

Summary: Brassinosteroids (BRs) are essential for growth and development in seed plants, controlling mitotic activity in meristems and organ boundaries, and meristem determinacy. The signaling cascade of BR perception and regulation of transcriptional regulators has been described in detail in model angiosperms, with homologs found in streptophyte algae and land plant lineages. The transcription factor MpBES1, present in the bryophyte Marchantia polymorpha, has similar functions to AtBES1 and AtBZR1 in Arabidopsis, indicating a shared evolutionary role in controlling cell division and differentiation in plants.

Summary: A simple and efficient protocol for the genetic transformation of Japanese larch was developed and multiple transgenic cell lines were obtained. However, the expression levels of exogenous genes in the transgenic system were relatively low, possibly due to the large genome of Japanese larch.

Summary: This study presents an optimized transformation system that improves the infection and genetic transformation frequency of immature maize embryos mediated by Agrobacterium tumefaciens. The use of LaCl3 pretreatment enhances the infection frequency, increases the proportion of positive callus, yields more positive regenerated plantlets, and significantly increases the transformation frequency from 8.40% to 17.60%.

Summary: The acquisition of new gene regulatory networks controlled by transcription factors is necessary for the evolution of special types of cells. In this study, it was found that a module formed by subfamilies Ia and IIIb basic helix-loop-helix transcription factors regulates the development of a unique sporophyte tissue, the seta, in the astomatous liverwort Marchantia polymorpha. This module also partially replaces the stomatal function in Arabidopsis thaliana, implying a common regulatory mechanism underlying setal and stomatal formation.

Summary: The liverwort Marchantia polymorpha has been a model plant in biological studies since the 18th century and is currently experiencing a Renaissance in genomic and genetic research. Its simple cultivation, worldwide distribution, ease of crossing, and availability of genetic tools make it an ideal model organism for studying physiological, developmental, and evolutionary aspects of land plants.
