| Abstract |
Rice blast, caused by Magnaporthe oryzae (M. oryzae), is one of the most common and damaging diseases of rice that limits rice yield and quality. The mediator complex plays a vital role in promoting transcription by bridging specific transcription factors and RNA polymerase II. Here, we show that the rice mediator subunit OsMED16 is essential for full induction of the diterpenoid phytoalexin biosynthesis genes and resistance to the ascomycetous fungus M. oryzae. Mutants of Osmed16 show reduced expression of the DP biosynthesis genes and are markedly more susceptible to M. oryzae, while transgenic plants overexpressing OsMED16 increased the expression of the DP biosynthesis genes and significantly enhanced resistance to M. oryzae. Interestingly, OsMED16 is physically associated with the WRKY family transcription factor OsWRKY45, which interacts with the phytoalexin synthesis key regulator transcription factor OsWRKY62. Further, OsMED16-OsWRKY45-OsWRKY62 complex could bind to the promoter regions of phytoalexin synthesis-related genes and activate their gene expression. Our results show that OsMED16 may enhance rice tolerance to M. oryzae via directly manipulating phytoalexin de novo biosynthesis. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 01 April 2024.
All research outputs
#17,472,025
of 25,630,321 outputs
Outputs from Rice
#212
of 437 outputs
Outputs of similar age
#81,014
of 162,049 outputs
Outputs of similar age from Rice
#3
of 4 outputs
Altmetric has tracked 25,630,321 research outputs across all sources so far. This one is in the 21st percentile – i.e., 21% of other outputs scored the same or lower than it.
So far Altmetric has tracked 437 research outputs from this source. They receive a mean Attention Score of 4.1. This one is in the 37th percentile – i.e., 37% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 162,049 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 38th percentile – i.e., 38% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 4 others from the same source and published within six weeks on either side of this one.
