培养下一代的植物学家——创新性的教学工具the Plant Teaching Tools

Oxford University Press to publish American Society of Plant Biologists journals

Frequently Asked Questions Regarding the American Society of Plant Biologists’ Partnership with Oxford University Press The American Society of Plant Biologists (ASPB) is delighted to announce that it will partner with Oxford University Press (OUP) to produce and disseminate the ASPB journals Plant Physiology® and The Plant Cell beginning January 2021. The following question/answer pairs […]

Plant Direct Q&A with Judy Brusslan

What does your lab work on? My lab is interested in the regulation of leaf senescence (LS). As leaves sequentially age, they enter a regulated dismantling process that exports nutrients to growing and storage organs. Tell us about the key findings from your recent article in Plant Direct. We wanted to find genetic evidence that histone […]

ASPB and NAASC: “Changing Cultures and Climates” Initiative

By Asia Hightower, Edith Pierre-Jerome, and Imani Madison In light of historical and recent world events, ASPB and NAASC (North American Arabidopsis Steering Committee) are partnering to further equity, diversity, and inclusion (EDI) initiatives that are in alignment with the missions of both societies. In the coming weeks, a group of individuals affiliated with these […]

Review: Emerging mechanisms to fine-tune receptor kinase signaling specificity (COPB)

Maybe it’s because I’ve spent too much time in lockdown, but sometimes I find studies on cell signaling a bit impenetrable. Fortunately, this excellent review by Galindo-Trigo et al. has arrived, which elegantly walks the reader through the crowded world of receptor-like kinases and “how cells can exert highly localized control over the assembly, interaction […]

Modifying plant photosynthesis and growth via simultaneous chloroplast transformation of Rubisco large and small subunits (Plant Cell)

In an interesting evolutionary artifact, the genes encoding the small subunit of Rubisco, rbcS, reside in the nuclear genome, whilst those encoding RbcL persists in the chloroplast. The RbcS protein is translocated into the chloroplast where the holoenzyme forms. This complexity adds to the challenge of engineering Rubsico, and several efforts have been made to […]

Variation in maize chlorophyll biosynthesis alters plant architecture (Plant Physiol)

This is an interesting paper that combines classical genetics with biochemistry and phenotypic analysis. Khangura et al. looked at maize lines with various allelic combinations of two loci that affect chlorophyll biosynthesis: the oil yellow1 (oy1) gene encodes magnesium chelatase, the first committed step in chlorophyll production, and very oil yellow1 (vey1) is a cis-regulatory […]
