Abstract Phosphorus (P) is a macronutrient necessary for plant growth and development. Inorganic phosphate (Pi) deficiency modulates the signaling pathway of phytohormone jasmonate in Arabidopsis thaliana, but underlying molecular mechanism currently remains elusive. Here, we confirmed that was enhanced under low Pi conditions, CORONATINE INSENSITIVE1 (COI1)-mediated critical this process. A mechanistic investigation revealed several JASMONATE ZIM-DOMAIN (JAZ) repressors physically interacted with signaling-related core transcription factors PHOSPHATE STARVATION RESPONSE1 (PHR1), PHR1-LIKE2 (PHL2), PHL3. Phenotypic analyses showed PHR1 its homologs positively regulated jasmonate-induced anthocyanin accumulation root inhibition. stimulated expression jasmonate-responsive genes, whereas JAZ proteins interfered transcriptional function. Furthermore, associated basic helix–loop–helix (bHLH) MYC2, MYC3, MYC4. Genetic biochemical assays indicated MYC2 synergistically increased downstream genes responses to jasmonate. Collectively, our study reveals crucial regulatory roles modulating provides understanding how functions together maintain appropriate level conditions deficiency.

Boron (B) is an essential microelement for plants, and its deficiency can lead to impaired development function. Around 50% of arable land in the world acidic, low pH soil solution decreases availability several mineral elements, including B, magnesium (Mg), calcium (Ca), potassium (K). Plants take up B form boric acid (H 3 BO ) acidic or tetrahydroxy borate [B(OH) 4 ] - at neutral alkaline pH. participate directly indirectly plant metabolism, synthesis cell wall plasma membrane, carbohydrate protein formation ribonucleic (RNA). In addition, interacts with other nutrients such as Ca, nitrogen (N), phosphorus (P), K, zinc (Zn). this review, we discuss mechanisms uptake, translocation, accumulation interactions how it contributes adaptation plants different environmental conditions. We also potential B-mediated networks physiological molecular levels involved growth development.

Endophytic plant growth promoting rhizobacteria (PGPRs) could replace chemical fertilizers in sustainable agriculture. Unfortunately, they are susceptible to harsh environmental conditions. Here, we proposed a polymeric hydrogel (PMH) consisting of carboxymethyl chitosan, sodium alginate, and calcium chloride for loading protecting endophytic PGPR. This can load PGPRs not only boost its growth-promoting efficiency, but also help them adapt more effectively environments. Using PGPR Ensifer C5 as model bacteria Brasscia napus host, demonstrate that the PMH facilitate colonization apical lateral root primordia regions. Further analysis indicates modulate suberin deposition endodermal cell layers regulate accumulation auxin at tip. Meanwhile, enhances antioxidant capacity disease resistance properties plants by increasing content arachidonic acid metabolism intermediates plant. Importantly, combination increases yields B. approximately 30% field. Furthermore, attenuates loss activity acidic Overall, this microbial encapsulation strategy is promising way protect fragile microorganisms, providing attractive avenues Plant fertilizers, authors report on protective enhance improve adaptability soil.

Abstract

Phosphorus is an essential macronutrient for plant development and metabolism, plants have evolved ingenious mechanisms to overcome phosphate (Pi) starvation. However, the molecular underlying regulation of shoot root architecture by low phosphorus conditions coordinated utilization Pi nitrogen remain largely unclear. Here, we show that Nodulation Signaling Pathway 1 (NSP1) NSP2 regulate rice tiller number promoting biosynthesis strigolactones (SLs), a class phytohormones with fundamental effects on environmental responses. We found NSP1 are induced Oryza sativa PHOSPHATE STARVATION RESPONSE2 (OsPHR2) in response low-Pi stress form complex directly bind promoters SL genes, thus markedly increasing rice. Interestingly, NSP1/2–SL signaling module represses expression CROWN ROOTLESS 1 (CRL1), newly identified early SL-responsive gene roots, restrain lateral density under deficiency. also demonstrated GR24^4DO treatment normal inhibits OsNRTs OsAMTs suppress absorption but enhances OsPTs promote absorption, facilitating balance between uptake Importantly, NSP1p:NSP1 NSP2p:NSP2 transgenic improved agronomic traits grain yield low- medium-phosphorus conditions. Taken together, these results revealed novel regulatory mechanism starvation, providing genetic resources improving nutrient-use efficiency environments.

As an essential macronutrient, phosphorus (P) is often a limiting nutrient because of its low availability and mobility in soils. Drought major environmental stress that reduces crop yield. How plants balance combine P-starvation responses (PSRs) drought resistance unclear. In this study, we identified the transcription factor ZmPHR1 as regulator PSRs modulates phosphate (Pi) signaling homeostasis. We found maize zmphr1 mutants had reduced P concentration were sensitive to Pi starvation, whereas ZmPHR1-OE lines displayed elevated yields. addition, 57% PSR genes nearly 70% ZmPHR1-regulated leaves transcriptionally responsive drought. Under moderate early conditions, decreased, up-regulated before drought-responsive genes. The exhibited drought-resistant phenotypes stomatal apertures, opposite was true mutants.
