Plant Cell Focus Issue on climate change and plant abiotic stress biology

The January 2023 issue of The Plant Cell includes a focus issue on “Climate change and plant stress: From genes to ecosystems”. This timely focus issue has in it commentaries, reviews, and research articles on the topic. I particularly enjoyed reading the two reviews that include short perspectives…

Perspective: Multiple mechanism behind plant bending

Bending or folding in plants is influenced by different factors such as environmental conditions (nutrient, water, light, gravity), abiotic or biotic stress, cell wall properties, and cell differential growth. Jonsson et al. explain how bending is achieved by considering molecular mechanisms, mathematical…

Review: The establishment of plants following long-distance dispersal

Seed dispersal is a critical ecological process with far-reaching implications. On rare occasions, seeds can be dispersed over vast distances, far beyond the range of the species. These events, known as long-distance dispersal, have profound evolutionary implications by expanding species distribution…

Control of guard cell aperture by protein kinase CIPK23

Guard cells are responsible for the opening and closing of stomata through changes in osmotic content and turgor pressure. These changes occur in response to activation or inactivation of ion transport proteins that are in turn regulated by protein kinase and phosphatase networks. The kinase network…

Contribution of strigolactones to maize kernel domesticated phenotype

We’ve all seen striking photographs comparing the modern maize (Zea mays spp. mays L.) ear to the seed head of its wild-grass ancestor teosinte (Zea mays spp. parviglumis). Besides the huge increase in size, one of the features that allows us to munch on “corn on the cob” is the absence of the…

eINTACT – An effective system for isolating effector-recipient cells in plant tissues

Bacteria can cause plant diseases by secreting small molecules called effectors. Studies of these effectors on host plants mostly have not accounted for the cellular complexity of plant tissues. The difficulty of detecting and isolating effector-recipient cells means that scientists mostly use bulk-infected…

Targeted A-to-G base editing of chloroplast DNA in plants

The chloroplast has its own genome which encodes proteins needed for chloroplast function. Editing these genes via CRISPR-Cas9 is difficult due to challenges in targeting guide RNAs to the chloroplast. Instead, base editors can be used, but these were originally developed for cytosine to thymine edits…

A successful genetic transformation procedure for turnip

Genome editing has strong potential for crop improvement, but its application is restricted by low plant regeneration frequencies and genotype dependencies. Despite its agricultural significance, research on turnip (Brassica rapa var. rapa) is hindered by a low efficiency of transformation and shoot…

Flash flaming enhances mechanized seed sowing for ecological restoration

One of the main challenges of seed-based restoration is incorporating seeds from as wide a variety of species as possible. However, the seeds of some species have shapes or appendages that make it challenging to use specialized machinery for direct seeding, which hinders large-scale restoration projects…
