The yellow-in-the-dark chIL Chlamydomonas mutant as a model for time-resolved chloroplast biogenesis and retrograde signaling
UncategorizedAbstractUnderstanding chloroplast biogenesis is key given the importance of photosynthesis and chloroplast metabolism. Chloroplast assembly has been extensively studied in angiosperms, where the main hallmarks have been established, including the need for nuclear and plastid genome coordination through…
From seawater to pyrenoid – The molecular architecture of the diatom CO2-concentrating mechanism
UncategorizedAbstractDiatoms are the most successful group of algae and their photosynthesis accounts for up to 20% of annual global CO2 fixation. A key factor to their ecological success is the operation of an efficient biophysical CO2-concentrating mechanism (CCM) that enriches CO2 for fixation by ribulose 1,5-bisphosphate…
CERK1-mediated phosphorylation of nitrilases activates auxin biosynthesis and promotes resistance to Botrytis cinerea
UncategorizedAbstractPlant immunity relies on dynamic modulation of phytohormone signaling to balance growth and defense, with auxin contributing to resistance against the necrotrophic pathogen Botrytis cinerea (B. cinerea). However, how plants rapidly and precisely regulate auxin biosynthesis during pathogen infection…
LF1 mediates brassinosteroid signaling to regulate leaf angle development in rice
UncategorizedAbstractLeaf angle is a key determinant of plant architecture and grain yield in rice, yet the complex genetic regulatory network remains unclear. Here, we reveal that the HD-ZIP III transcription factor LF1 mediates BR signaling to modulate leaf angle. A miRNA165/166-resistant, gain-of-function lf1…
OsWOX13 functions as a heading signal transducer from integrator Ehd1 to florigen for the accurate regulation of rice heading date
UncategorizedAbstractAppropriate heading date is an important safeguard for stabilizing rice yield and quality. Heading integrator Ehd1 and florigen Hd3a are crucial for rice heading. However, the mechanism by which Ehd1 transmits heading signals to Hd3a and the accurate regulation of Hd3a expression remains unclear.…
A novel allele of Sh1 facilitates the development of waxy-sweet corn from waxy corn
UncategorizedAbstractWaxy corn and sweet corn represent two major classes of fresh-eating corn, and each with distinct sensory attributes and nutritional compositions. Developing a new variety that combines both waxy and sweet traits would address rising consumer demand and expand new market potential. From a fast…
Crops of the Future: Reviving Neglected and Undertilized Crops for Global Nutrition Webinar Series (September 2 and 3)
UncategorizedAbout this Webinar Series: This webinar series will focus on underutilized crops, plant species of local or regional importance that have received limited attention in research, breeding, and policy compared with global staples such as rice, maize, and wheat. These crops hold significant potential to…
Turning over a green leaf: integrating light signals towards chloroplast establishment
UncategorizedAbstractLight is indispensable for transitioning from a heterotrophic to a photoautotrophic state. Etiolated seedlings, developed in darkness, are primed for rapid chloroplast development upon light exposure. In this transition, dark-adapted etioplasts differentiate into functional chloroplasts through…
