Evolutionary Analysis and Functional Identification of Ancient Brassinosteroid Receptors in <i>Ceratopteris richardii</i> by Bowen Zheng, Kaixin Xing, Jiaojiao Zhang, Hui Liu, Khawar Ali, Wenjuan Li, Qunwei Bai, Hongyan Ren

“…Brassinosteroids (BRs) are essential hormones that regulate multiple aspects of plant growth and development in angiosperms, but the presence of BR signaling in non-seed plants such as ferns remains unknown. Here, we found that BR promotes the growth of <i>Ceratopteris richardii</i>, while the synthetic inhibitor PCZ inhibits the growth. …”

Variation in leaf mesophyll anatomy of fern species imposes significant effects on leaf gas exchange, light capture, and leaf hydraulic conductance by S. FUJII, K. NISHIDA, T.K. AKITSU, A. KUME, Y.T. HANBA

“…However, such simultaneous analyses have been scarcely performed, particularly on non-seed plants. Using seven fern species, we first showed that fern species with a large mesophyll thickness had a high photosynthetic rate related to high light capture, high drought tolerance, and low leaf hydraulic conductance. …”

<i>YABBY</i> Genes in the Development and Evolution of Land Plants by Marina A. Romanova, Anastasiia I. Maksimova, Katharina Pawlowski, Olga V. Voitsekhovskaja

“…The key transcription factors responsible for leaf blade development in angiosperms are YABBY proteins, which until recently were thought to be unique for seed plants. Yet, identification of a YABBY homologue in a green alga and the recent findings of YABBY homologues in lycophytes and hornworts suggest that YABBY proteins were already present in the last common ancestor of land plants. …”

Quantitative live-imaging reveals the dynamics of apical cells during gametophyte development in ferns by Xiao Wu, An Yan, Xing Liu, Shaoling Zhang, Yun Zhou

“…Meristems in seed-free plants, including ferns, usually contain one or a few pyramid-/wedge-shaped apical cells (ACs) as initials, which are lacking in seed plants. It remained unclear how ACs promote cell proliferation in fern gametophytes and whether any persistent AC exists to sustain fern gametophyte development continuously. …”
