Abstract :
Heat stress significantly impacts global rice production, highlighting the critical need to understand the genetic basis of heat resistance in rice. U2AF (U2 snRNP auxiliary factor) is an essential splicing complex with critical roles in recognizing the 3 '-splice site of precursor messenger RNAs (pre-mRNAs). The U2AF small subunit (U2AF35) can bind to the 3 '-AG intron border and promote U2 snRNP binding to the branch-point sequences of introns through interaction with the U2AF large subunit (U2AF65). However, the functions of U2AF35 in plants are poorly understood. In this study, we discovered that the OsU2AF35a gene was vigorously induced by heat stress and could positively regulate rice thermotolerance during both the seedling and reproductive growth stages. OsU2AF35a interacts with OsU2AF65a within the nucleus, and both of them can form condensates through liquid-liquid phase separation (LLPS) following heat stress. The intrinsically disordered regions (IDR) are accountable for their LLPS. OsU2AF35a condensation is indispensable for thermotolerance. RNA-seq analysis disclosed that, subsequent to heat treatment, the expression levels of several genes associated with water deficiency and oxidative stress in osu2af35a-1 were markedly lower than those in ZH11. In accordance with this, OsU2AF35a is capable of positively regulating the oxidative stress resistance of rice. The pre-mRNAs of a considerable number of genes in the osu2af35a-1 mutant exhibited defective splicing, among which was the OsHSA32 gene. Knocking out OsHSA32 significantly reduced the thermotolerance of rice, while overexpressing OsHSA32 could partially rescue the heat sensitivity of osu2af35a-1. Together, our findings uncovered the essential role of OsU2AF35a in rice heat stress response through protein separation and regulating alternative pre-mRNA splicing.

Abstract :
Understanding the regulatory mechanisms underlying the plant heat stress response is important for developing climate-resilient crops, including rice (Oryza sativa). Here, we report that OsEIL5, one member of the ETHYLENE INSENSITIVE3-LIKE family, positively regulates rice heat tolerance at the seedling and reproductive stages. OsEIL5 directly binds to the promoter of OsPP91 (encoding one type 2C protein phosphatase) and activates its expression. OsPP91 is required for rice thermotolerance, and overexpressing OsPP91 in oseil5-1 partially rescues its heat sensitivity. The F box protein OsEBF1 interacts with OsEIL5 and degrades it through the ubiquitination pathway, resulting in the reduction of OsPP91 expression and ultimately weakening rice heat tolerance. Knocking out OsEIL5 in the EBF1R13 line partially reduces its extremely high heat tolerance. Taken together, our work uncovers a mechanism that finely regulates rice thermotolerance through the OsEBF1-OsEIL5-OsPP91 module at the posttranslational and transcriptional levels.

Abstract :
White lupin (Lupinus albus L.) produces cluster roots to acquire more phosphorus under phosphorus deficiency. Bacillus amyloliquefaciens SQR9 contributes to plant growth, but whether and how it promotes cluster root formation in white lupin remain unclear. Here, we investigated the roles of SQR9 in cluster root formation under low phosphorus conditions using a microbial mutant and virus-induced gene silencing (VIGS) in white lupin. SQR9 substantially enhanced cluster root formation under low phosphorus conditions. The ysnE gene encodes an auxin biosynthesis enzyme in SQR9 and was associated with cluster root formation, as ysnE-defective SQR9 did not trigger cluster root formation. SQR9 inoculation induced the expression of PIN-formed2 (LaPIN2, encoding an auxin transporter) and YUCCA4 (LaYUC4, encoding an auxin biosynthesis enzyme) in white lupin roots. VIGS-mediated knockdown of LaPIN2 and LaYUC4 prevented wild-type SQR9-induced cluster root formation in white lupin. Finally, white lupin LaYUC4-derived auxin and SQR9-derived auxin pools were both transported by LaPIN2, promoting cluster root formation under low phosphorus conditions. Taken together, we propose that B. amyloliquefaciens promotes cluster root formation in white lupin under low phosphorus conditions by stimulating auxin biosynthesis and transport. Our results provide insights into the interplay between bacteria and root auxin in crop phosphorus use efficiency. Bacillus amyloliquefaciens produces auxin and promotes auxin biosynthesis in white lupin under low phosphorus conditions, triggering cluster root formation.

Abstract :
White lupin exhibits remarkable adaptability to phosphorus (P)-deficient soil through the development of cluster roots (CR), thereby enhancing P use sufficiency. Despite its crucial role, the underlying mechanism governing CR formation remains elusive. Here, we reveal an elevated DNA methylation level through whole-genome bisulfite sequencing in CR in response to P deficiency, particularly in gene and flanking regions, suggesting a responsive epigenetic mechanism. To further investigate the potential involvement of epigenetic remodelling, we treated lupin plants with the DNA methyltransferase (DNMT) inhibitor 5-azacytidine, which led to a disruption of total DNMT activity and impaired CR formation under phosphorus-deficient conditions. Integrated analysis of methylome and RNA-Seq highlights the methylation of CAFFEIC ACID O-METHYLTRANSFERASE 1 (COMT1), a key enzyme in melatonin synthesis, as pivotal for promoting CR formation in white lupin. Functional validation through overexpression or gene silencing of LaCOMT1 in transgenic lupin roots confirms the positive impact of LaCOMT1 on CR formation. Furthermore, melatonin application directly increases CR numbers, indicating the role of methylation-activated LaCOMT1 in promoting CR formation via melatonin synthesis. Those findings provide insights into the epigenomic landscape of white lupin, establishing a direct genetic link between epigenetic mechanisms and P-deficiency-induced CR formation.

Abstract :
Intracellular Ca2+ controls various cellular functions and local Ca2+ dynamics are tightly regulated upon environmental cues. Maintaining cellular Ca2+ balance is essential for plant survival. Here we report a calcium-dependent protein kinases (CPKs)-mediated signaling pathway, in conjunction with the ER membrane-resident Ca2+-ATPase ECA1, acts influentially for cytosolic Ca2+ homeostasis and osmotic stress tolerance. We show that targeting cytosolic Ca2+ efflux via specific inhibitors or eca1 mutation results in augmented [Ca2+]cyt spikes, elevated cytoplasmic ABA ([ABA]cyt) level and ultimately hypersensitive to osmotic stress. Screening of Arabidopsis CPKs revealed direct binding of CPK2/6/11 to ECA1. Moreover, CPK2/6/11 phosphorylates the N-terminal of ECA1 at Ser5, thereby enhancing its activity for cytosolic Ca2+ efflux into ER and subsequently lowering [ABA]cyt. The cumulative effect of ECA1 and CPKs mutation on Arabidopsis plant sensitivity to osmotic stress further illustrates that CPKs/ECA1 acts as an intracellular module for tuning stress response via regulating [Ca2+]cyt and [ABA]cyt homeostasis. © 2025, The Authors.
