Two blue-light photoreceptors (cry1 and phot1) function differently in hypocotyl light responses

Plants have several types of light receptors that control various responses to light, such as leaf expansion, time-of-flowering, and hypocotyl elongation. When seeds are germinated in the dark, their hypocotyl elongates rapidly because darkness is perceived as being deep underground; the elongation is an effort to reach light. Hypocotyl elongation is quickly arrested in the […]

Single cell analysis of wheat spike development

This preprint wins the award for “most beautiful paper” this week. Xu, Lin et al. carried out an expression analysis of developing wheat spikes at three developmental stages, using both single-cell RNA sequencing and single-molecule fluorescence in situ hybridization (smFISH). The wheat spike is the inflorescence where the grain ultimately forms, so it is responsible […]

A mutation in a nuclear-membrane localized calcium channel enhances symbiosis

Calcium oscillations are widely employed molecular signals, but how signals are encoded and decoded remains largely unknown. In a new study, Cook et al. investigated mutations in the nuclear envelope-localized calcium channel CNGC15 from the legume Medicago truncatula. This protein normally forms a complex with a second calcium channel protein, DMI1, and together they mediate […]

Review: The complexities of metabolite transport in C4 photosynthesis C4 photosynthesis, an adaptive mechanism to spatially concentrate CO2 around Rubisco to enhance carbon fixation, has evolved independently at least 60 times in plants. This process spatially separates the initial carbon fixation by PEPC and carbon reduction by Rubisco, which requires that compounds move in and […]

Perspective: How should the advancement of large language models affect the practice of science?

Perspective: How should the advancement of large language models affect the practice of science? In this thought-provoking Perspective, four sets of authors express their opinions about the use of Large Language Models (such as ChatGPT) in the practice of science. Each essay is well reasoned, and each identifies both strengths and limitations of LLMs. There’s […]

Diversity and genetic basis of hydropatterning in inbred maize lines

For more than a hundred years, plant biologists have been fascinated by how plants sense and respond to environments that are spatially and temporally heterogenous.  Many of these responses occur through the remarkable developmental plasticity of plant growth, such as phototropism and photomorphogenesis. Below ground, root growth and branching patterns as well as root hair […]
