Unveiling root trait syndromes in trees: Evolutionary insights into mycorrhizal partnerships
Plant Science Research WeeklyPlants, particularly long-lived trees, need to balance nutrient acquisition, herbivore and pathogen defence, and ultimately organic matter decomposition. The intricate relationship between these processes is crucial for the survival and growth of trees over their extended lifespans. Zheng et al. investigated…
Forests endure as critical carbon sinks
Plant Science Research Weekly
The global forest carbon sink is vital for mitigating climate change by absorbing CO2 and offsetting nearly half of fossil-fuel emissions. Over the past three decades, this sink has remained stable with minor fluctuations, but its future is threatened by deforestation, forest ageing, and climate…
Review: Stem cells of the vascular cambium
Plant Science Research WeeklyVascular cambium cells are meristematic cells responsible for secondary growth. Lineage tracing studies in Arabidopsis and poplar show the presence of single bifacial stem cells in each radial cell file that produce xylem inwards and phloem cells outwards. In a recent review, Wybouw et al. discuss the…
Review: Role of silicon in drought tolerance
Plant Science Research WeeklyThere is increasing evidence that silicon (Si) application to soils or leaves can promote plant growth through various means, including enhancing tolerance to abiotic and biotic stresses, but the mechanisms of this growth promotion are not always clear. Here, Bardhan et al. review how Si can promote…
Transposase-assisted target-site integration for efficient plant genome engineering
Plant Science Research WeeklyGenome editing stands at the forefront of scientific innovation, offering transformative possibilities to manipulate the genetic code of plants, animals, and humans. A critical bottleneck for its application in modern crop improvement is the low frequency and error-prone integration of foreign DNA into…
Identification of plant transcriptional activation domains
Plant Science Research WeeklyActivation domains (AD) are parts of transcription factor proteins (TFs) that bind the transcriptional machinery (coactivator complexes) and lead to transcriptional activation. However, identifying ADs is challenging because they are often part of intrinsically disordered regions, which lack a defined…
CarboTag for live-imaging of plant cell walls
Plant Science Research WeeklyRecently, we have gained tremendous insights through live-cell imaging using fluorescent tags that bind specifically to various cellular components. Here, Besten et al. present a new set of cell wall-specific tags that bind specifically to cell walls and reveal selected wall properties. The authors developed…
Characterization of pyrenoid-based CO2-concentrating mechanism in hornworts
Plant Science Research WeeklyPyrenoids are structures that concentrate carbon dioxide around Rubisco, most commonly studied in green algae such as Chlamydomonas. However, hornworts, one of the three types of bryophytes (along with liverworts and mosses) also have a pyrenoid-based CO2-concentrating mechanism (pCCM), unique among…
Tissue-specific interference reveals complex roles for auxin signalling in procambial cells during graft healing in Arabidopsis
Plant Science Research WeeklyFor hundreds of years, we have propagated plants clonally by grafting, i.e. the union of a scion and a rootstock to form a new plant. To be successful, a graft junction must heal: tissues must attach, and vascular bundles reconnect, in a process known to involve auxin. Here, Serivichyasw at et al. investigate…
