With the 50-year rise of Arabidopsis as the most studied plant, is it time for its downfall?

Let’s investigate it’s history and outlook 🧵

In all land plants, small secreted peptides belonging to the CLE family move from cell to cell and activate their cognate receptors to control a plethora of developmental processes - Cornelis & Hazak

Box 1. (shortened, full legend in paper): Key developments in understanding the role of CLE signalling in plant development. This scheme represents a summary on the selected latest advances in CLE signalling. (A) In a series of publications, Yuki Hirakawa and his team (Takahashi et al., 2021, 2023) characterized the CLE pathway in the liverwort Marchantia polymorpha that positively controls cell divisions via repressing the transcription factor JINGASA. (B) In Arabidopsis, CLV3/CLV1 signalling in the shoot was found to be buffering auxin-dependent development under different thermal conditions (John et al., 2023). (C) Research from several teams showed that the BAM3/CLE pathway is crucial for root protophloem development (Hu et al., 2018, 2022; Qian et al., 2022; Carbonnel et al., 2023). Moreover, the study by Carbonnel et al. (2023) identified an uncharacterized Arabidopsis CLE33 gene that acted in concert with CLE45 via BAM3 in root protophloem development.

Many species of Selaginella (#Selaginellaceae) have two kinds of leaves (microphylls): Spreading, distichously arranged leaves and a second kind of leaf appressed to the stem. This is Selaginella picta. Classic #anisophylly! #TropicalBotany #Botany 🌾🧪🌱

(C–L) Representative images of gametophytes at different days after inoculation onto growth medium: (C) 20, (D) 31, (E) 86, (F–J) 111, (K) 133, and (L) 129. Arrows in (G–K) indicate meristem notches. The dashed circle in (L) highlights a cluster of multiple meristems and prothalli derived from a single gametophyte body. Scale bars are 5 mm in (A, L) and 100 μm in (B–K). The gametophyte shown in (I) developed independent new meristems (arrows); the one on the left is also shown in Supplementary Fig. S2C. The images shown in (C–E) and in (F–K) are representative of at least 40 and 12 independent gametophytes observed during the developmental stages, respectively.
