“…Moreover, osa-mi319/OsTCP21 [27], osa-miR444/OsMADS57 [26], osa-miR171b/OsSCL6-IIa, OsSCL6-IIb, OsSCL6-IIc [25] and osa-miR528/OsAO [24] regulatory units could change the disease development caused by rice stripe virus and rice ragged stunt virus, respectively. However, only two regulatory units, osa-miR156/OsIPA1 [31] and osa-miR169o/OsNF-YA [32], were published, which mediated immunity to Xoo. Integrating analysis of small RNA sequencing and degradome data showed that 29 DE known miRNAs might be involved in anti-bacterial regulatory mechanism in BB.…”

“…Regarding applied potential, osa-miR1861k induced by multiple Xoo strains in resistant rice genotypes may mediate a broad spectrum resistance [30]. The inducible knockdown of osa-miR156 could motivate OsIPA1 expression, to debar the fitness penalty of BB resistance in rice [31]. Conversely, the enhancive osa-miR169o boosted the pathogenicity of Xoo strains [32].…”

MicroRNAs (miRNAs) are crucial player in plant-pathogen interaction. While the evidence has demonstrated that rice miRNAs mediate immune response to pathogens invasion, the roles of miRNAs on Xanthomonas oryzae pv. oryzae (Xoo) attack remain be in place. Herein, we monitored the responsive changes of rice miRNAs at 0, 8, 24 h across Xoo strain PXO86 infection in its compatible rice variety IR24 and incompatible variety IRBB5 by small RNA sequencing, and the genes targeted by miRNAs were also detected via degradome technology. The faithfulness of sequencing data was validated through quantitative real-time stem-loop reverse transcription-polymerase chain reaction assay. Bioinformatic analysis showed that the differentially expressed miRNAs could be divided into three immunity-related clusters, and 80 regulatory units were emerged in infection process, which comprises 29 differentially expressed known miRNAs and 38 cleaved targets. Furthermore, the miRNA presumptive function of separate immunity cluster in rice-Xoo interplay was confirmed through overexpressing osa-miR164a, osa-miR167d and osa-miR159b, and the disruption of regulatory units, osa-miR164a/OsNAC60, osa-miR167d-5p/OsWD40-174 and osa-miR159b/OsMYBGA, OsLRR-RLK2, OsMPK20-4, may reset rice defense response to Xoo infestation in a controllable manner. These findings provide new insights into the complex roles of characteristic miRNAs and their targets in rice-Xoo interactions.

“…Understanding sRNA-mediated regulation of the trade-offs between plant defense and growth can also provide guidance in generating resistant crops with minimum fitness cost. For example, downregulation of rice miR156 or overexpression of its targets, Ideal Plant Architecture1 (IPA1) and SQUAMOSA promoter-binding protein-like transcription factor, OsSPL7, in rice leads to enhanced resistance to the bacterial blight Xoo but with reduced yield (Liu et al, 2019). Overexpression of IPA1 under a bacterial effector-induced promoter can ensure its activation only upon pathogen attack, which largely avoids the fitness penalty and increases disease resistance against Xoo (Liu et al, 2019).…”

Eukaryotic small RNAs (sRNAs) are short non-coding regulatory molecules that induce RNA interference (RNAi). During microbial infection, host RNAi machinery is highly regulated and contributes to reprogramming gene expression and balancing plant immunity and growth. While most sRNAs function endogenously, some can travel across organismal boundaries between hosts and microbes and silence genes in trans in interacting organisms, a mechanism called ''cross-kingdom RNAi.'' During the co-evolutionary arms race between fungi and plants, some fungi developed a novel virulence mechanism, sending sRNAs as effector molecules into plant cells to silence plant immunity genes, whereas plants also transport sRNAs, mainly using extracellular vesicles, into the pathogens to suppress virulence-related genes. In this Review, we highlight recent discoveries on these key roles of sRNAs and RNAi machinery. Understanding the molecular mechanisms of sRNA biogenesis, trafficking, and RNAi machinery will help us develop innovative strategies for crop protection.

“…Rice SQUAMOSA PROMOTER-BINDING PROTEIN-LIKE (SPL) gene OsSPL14 (Ideal Plant Architecture 1, IPA1) encodes a plant-speci c transcription factor and is a new "Green Revolution" gene, which plays a critical role in regulating rice ideal plant architecture [1][2][3]. Therefore, the optimal increased expression of OsSPL14 in rice could confer ideal plant architecture including reduced tiller number, increased panicle primary branching, elevated lodging resistance of stems, at the same time increased thousand-grain weight [4][5][6].…”

Background SQUAMOSA PROMOTER-BINDING PROTEIN-BOX gene OsSPL14 from rice is evaluated as the major gene for ideal plant architecture consisting of few unproductive tillers, more grains per spike and high lodging resistance stems. However, the function of its orthologous gene TaSPL14 in wheat is still unknown. Results Here, we reported the similarity and variation between TaSPL14 and OsSPL14. Similar to OsSPL14, TaSPL14 knock-out mutants exhibited decreased plant height, spike length, spikelet number, thousand-grain weight. Different from OsSPL14, TaSPL14 had no effect on tiller number. Transcriptome analysis genes related to ethylene response were significantly decreased in young spikes of TaSPL14 knockout mutants, compared with wild type. TaSPL14 directly binds to the promoters of the ethylene response gene TaEIL1 (EIN3-LIKE 1), TaRAP2.11 (ETHYLENE-RESPNSIVE TRANSCRIPTION FACTOR 2.11) and TaERF1 (ETHYLENE-RESPNSIVE TRANSCRIPTION FACTOR 1) and activities their expression, suggesting that TaSPL14 might regulate wheat spike development through ethylene response pathway. Conclusions TaSPL14 had similar function with OsSPL14 in regulating plant height, spike length, spikelet number and thousand-grain weight of wheat, and had different function in tiller development. TaSPL14 might regulate spike development through TaEIL1, TaRAP2.11 and TaERF1, not TaDEP1.The elucidation of TaSPL14 will contribute to exploring the molecular mechanisms underlying plant architecture of wheat.
