Genome-edited powdery mildew resistance in wheat without growth penalties

Shengnan Li et al.

Summary: Disruption of susceptibility genes in crops can confer disease resistance, but often leads to undesired effects. This study identifies a mutant wheat variety with a targeted deletion in a specific gene that retains crop growth and yields while conferring robust resistance to powdery mildew.

Coordinated resource allocation to plant growth-defense tradeoffs

Russell K. Monson et al.

Summary: Plant resource allocation patterns often show a tradeoff between growth (G) and defense (D), with ecological theory and discoveries in multi-omics biology helping to understand the mechanisms behind these tradeoffs. Multi-omic studies provide insight into the coordinated resource allocation that justifies optimality theory and calibrates G-D tradeoff commitments. The coordinated resource allocation hypothesis (CoRAH) integrates supply- and demand-side perspectives of previous G-D tradeoff theories.

Steroidal alkaloids defence metabolism and plant growth are modulated by the joint action of gibberellin and jasmonate signalling

Sayantan Panda et al.

Summary: The study revealed the hormonal regulation of SGAs metabolism, showing that reduced active JA leads to decreased SGA production, while low levels of GA result in increased SGA accumulation. Furthermore, MYC1 and MYC2 transcription factors mediate the crosstalk between JA and GA pathways by regulating SGA biosynthesis and GA catabolism genes.

Fungal endophytes can eliminate the plant growth-defence trade-off

Daniel A. Bastias et al.

Summary: The association of plants with Epichloe fungal endophytes may eliminate the trade-off between growth and defence functions in plants by stimulating plant growth hormones and producing antiherbivore alkaloids. Research supports that enhanced plant resistance promoted by endophytes does not compromise plant growth, discussing the ecological benefits of this lack of trade-off.

Functional specificity, diversity, and redundancy of Arabidopsis JAZ family repressors in jasmonate and COI1-regulated growth, development, and defense

Bei Liu et al.

Summary: This study investigates the specificity, diversity, and redundancy of JAZ family repressors in regulating plant growth, development, and defense in response to jasmonates, particularly focusing on their roles in resistance to pathogens, root growth inhibition, flowering time delay, and defense against insects. The research shows that different groups of JAZ proteins have specific functions in various JA responses, with mutations in multiple JAZ members enhancing JA sensitivity and affecting transcriptional profiles regulated by COI1.

Growth-defense trade-offs and yield loss in plants with engineered cell walls

Chan Man Ha et al.

Summary: Lignin, a major component of plant cell walls, plays a crucial role in plant defense and structural integrity. However, genetic modification of lignin biosynthesis can lead to unexpected dwarf phenotypes in plants. Various hypotheses have been proposed to explain this phenomenon, including transcriptional reprogramming and growth-defense trade-offs, but a commonly accepted mechanism is still lacking.
