Complex biological processes such as plant growth and development are often under the control of transcription factors that regulate expression large sets genes activate subordinate in a cascade-like fashion. Here, by screening candidate photosynthesis-related rice, we identified DREB (Dehydration Responsive Element Binding) family member, OsDREB1C, which is induced both light low nitrogen status. We show OsDREB1C drives functionally diverse transcriptional programs determining...
Light-induced de-etiolation is an important aspect of seedling photomorphogenesis. GOLDEN2 LIKE (GLK) transcriptional regulators are involved in chloroplast development, but to what extent they participate photomorphogenesis not clear. Here, we show that ELONGATED HYPOCOTYL5 (HY5) binds GLK promoters activate their expression, and also interacts with proteins Arabidopsis (Arabidopsis thaliana). The chlorophyll content the de-etiolating seedlings hy5 glk2 double mutants was lower than single...
C4 plants typically operate a CO2 concentration mechanism from mesophyll (M) cells into bundle sheath (BS) cells. NADH dehydrogenase-like (NDH) complex is enriched in the BS of many NADP-malic enzyme (ME) type and more abundant than C3 plants, but to what extent it involved remains be experimentally investigated. We created maize rice mutants deficient NDH function then used combination transcriptomic, proteomic, metabolomic approaches for comparative analysis. Considerable decreases growth,...
Abstract Drought has become one of the most severe abiotic stresses experienced in agricultural production across world. Plants respond to water deficit via stomatal movements leaves, which are mainly regulated by abscisic acid (ABA). A previous study from our lab showed that constitutive expression maize (Zea mays L.) GOLDEN2-LIKE (GLK) transcription factors rice (Oryza sativa can improve conductance and plant photosynthetic capacity under field conditions. In present study, we uncovered a...
Low phosphate (Pi) availability decreases photosynthesis, with limitation of photosynthesis occurring particularly during grain filling cereal crops; however, effective genetic solutions remain to be established. We previously discovered that rice transporter OsPHO1;2 controls seed (sink) development through Pi reallocation filling. Here, we find regulates homeostasis and thus in leaves (source). Loss-of-function decreased levels leaves, leading photosynthetic electron transport activity, CO...
The carboxysome plays an essential role in the carbon concentration mechanism cyanobacteria. Although significant progress has been made structural analysis of carboxysome, little is still known about its biosynthesis. We identified slr1911, a gene encoding protein unknown function cyanobacterium Synechocystis sp. Strain PCC 6803 (Syn6803), which we termed ccmS by screening low CO2 -sensitive mutant. CcmS interacts with CcmK1 and CcmM. former shell β-carboxysome latter crucial component...

Summary Typical C 4 plants such as maize possess highly optimized Kranz-type leaf anatomy, whereby concentric wreaths of mesophyll and bundle sheath cells surround closely spaced veins. The veins the that them are derived from middle ground meristem (mGM) through processes yet undefined. Here we distinguished active zone vascular development within early primordia, used comparative transcriptomics sub-sectioned rice primordia to identify cohorts genes likely involved in Kranz development....
Summary Many of the world’s most productive food and bioenergy crops use C 4 photosynthesis, which have high photosynthetic efficiency due to a Kranz anatomy-based CO 2 concentrating mechanism. Here, we took comparative transcriptomics approach using single cell spatial transcriptomes leaf primordia for maize ( Zea mays ) RNA-seq (scRNA-seq) atlases corresponding tissues three species , Sorghum bicolor Setaria viridis one 3 rice Oryza sativa study regulatory networks involved in development...
Summary C 4 plants typically operate a CO 2 concentration mechanism from mesophyll (M) cells into bundle sheath (BS) cells. NADH dehydrogenase-like (NDH) complex is enriched in the BS of many NADP-ME type plants, and more abundant than 3 but to what extent it involved remains be experimentally investigated. We created maize rice mutants deficient NDH function, used combination transcriptomic, proteomic, metabolomic approaches for comparative analysis. Considerable decrease growth,...
Abstract The greening of young seedling is light induced but vulnerable to photo-oxidative stress at the same time, due immature status chloroplasts. Accumulation anthocyanin a protective response high light, by absorbing excess energy and serving as antioxidant. In this work with Arabidopsis, we found that GARP family transcription factors GOLDEN2-LIKE 2 (GLK2), key regulator chloroplast development, also plays an intensive role in regulating biosynthesis during de-etiolation, especially...
