Article Synopsis
- Wheat's yield is greatly influenced by tiller numbers, which are affected by phosphorus availability; increasing reliance on phosphorus fertilizers poses environmental risks.
- In experiments with the wheat variety Kenong 199 under low phosphorus stress, researchers found significant changes in gene expression, identifying 1651 upregulated and 827 downregulated genes related to phosphorus metabolism and growth regulation.
- The transcription factor TaWRKY74s was highlighted as crucial for low phosphorus tolerance, influencing tiller numbers, with RNAi transgenic plants showing reduced tillers compared to wild types, both under normal and low phosphorus conditions.
Genetic transformation is important for gene functional study and crop improvement. However, it is less effective in wheat. Here we employed a multi-omic analysis strategy to uncover the transcriptional regulatory network (TRN) responsible for wheat regeneration.

Article Synopsis
- Tillering is an important trait in wheat that influences both its growth and grain yield, with specific proteins like TFL1 playing a role in this process.
- The study utilized CRISPR/Cas9 to create wheat mutants with defective versions of the TFL1 gene, leading to a noticeable decrease in tiller production during plant growth.
- RNA-seq analysis indicated that the altered mutants had significant changes in gene expression related to auxin and cytokinin signaling, which are crucial for tiller development.
Background: Tiller number is a factor determining panicle number and grain yield in wheat (Triticum aestivum). Auxin plays an important role in the regulation of branch production. PIN-FORMED 1 (PIN1), an auxin efflux carrier, plays a role in the regulation of tiller number in rice (Oryza sativa); however, little is known on the roles of PIN1 in wheat.

Histone acetylation modification plays a vital role in plant cell division and differentiation. However, the function on wheat mature embryo culture has not been reported. Here, we used the mature embryo of wheat genotypes including CB037, Fielder, and Chinese Spring (CS) as materials to analyze the effects of different concentrations of trichostatin A (TSA) and sodium butyrate (SB) on plant regeneration efficiency.

YT521-B homology (YTH) domain-containing RNA-binding proteins are important RNA binding proteins that affect the fate of m6A-containing RNA by binding m6A. Little is known about the YTH genes in common wheat (Triticum aestivum L.
View Article and Find Full Text PDFTillering is a significant agronomic trait in wheat which shapes plant architecture and yield. Strigolactones (SLs) function in inhibiting axillary bud outgrowth. The roles of SLs in the regulation of bud outgrowth have been described in model plant species, including rice and Arabidopsis.
View Article and Find Full Text PDFPlants are known for their capacity to regenerate organs, such as shoot, root and floral organs. Recently, a number of studies contributed to understanding the mechanisms of shoot and root regeneration. However, the mechanisms underlying floral organ regeneration are largely unknown.

- Plant regeneration is crucial for research and agriculture, and varies significantly among different plant genotypes, with the novel thioredoxin DCC1 identified as a key factor influencing shoot regeneration capacity in Arabidopsis.
- Loss of DCC1 function disrupts shoot regeneration by reducing activity of the respiratory chain Complex I and causing increased production of reactive oxygen species (ROS), which inhibit gene expression related to regeneration.
- The study reveals that DCC1 plays a major role in shoot regeneration variability and suggests that regulating redox processes may enhance plant regeneration capabilities.
