Excited to be part of the 2026 Sahyadri Future Faculty Academy! I am grateful to @plantpostdocs.bsky.social for this opportunity and look forward to learning from my faculty mentor, connecting with this wonderful cohort, and strengthening my preparation for the academic job market.

Have you ever wondered why the same gray mold appears on so many fruits and vegetables? 🍓🍇🍅🧅 That familiar mold is Botrytis cinerea, one of the world's most successful plant pathogens. It infects more than 1,500 plant species, raising a long standing question.

Host killing by necrotrophs is really complex. Using a 29-gene knockout series in Botrytis cinerea, we show that removing nearly all known cell death-inducing proteins and major phytotoxins is not sufficient to prevent host necrosis. Check out the paper: www.biorxiv.org/content/10.6...

Deletion of 29 cell death-inducing proteins and phytotoxin biosynthetic genes does not completely abolish virulence of Botrytis cinerea
Botrytis cinerea is a necrotrophic plant pathogen with an extremely wide host range. During invasion, the fungus induces rapid host cell death and proliferates in the necrotic tissue. The mechanisms o...

Excited to share two new PNAS papers on Botrytis cinerea—the fungus that spoils nearly everything. Together, these studies explore how the pathogen infects diverse hosts and how plants respond across evolutionary diversity.

The Fungus That Spoils Nearly Everything
UC Davis scientists discovered gray mold adapts to different crops, revealing why decades of disease-resistant breeding failed.

🌱 From PNAS: Plant defenses against gray mold rely on shared stress responses but highly species-specific immune networks. (Ritu Singh, Anna Jo Muhich, Cloe Tom, Celine Caseys, Daniel J. Kliebenstein) ▶️ www.pnas.org/doi/10.1073/... #PlantScience #PlantPathology
Isolate-driven transcriptional responses across hosts. (A) PCA of host transcriptional responses based on the expression of 803 single-copy orthologs shared across all 10 eudicot hosts. To normalize for interspecific scale differences, expression values were z-scaled within each host prior to analysis. Points are colored by host species and shaped by treatment (circles = B. cinerea infected; triangles = mock). Mock samples are additionally highlighted with arrows. The percentage of variance explained by each principal component is indicated on the axes. (B) Rank heatmap of B. cinerea isolates based on their PC1 scores, which capture the primary axis of transcriptional variation. Isolates (columns) are ordered by their average rank across all hosts. Host species (rows) are arranged according to their phylogenetic relationships. The color scale represents the rank of each isolate within a host, where 1 (yellow) corresponds to the highest PC1 score (strongest transcriptional response) and higher ranks (purple) indicate weaker responses closer to mock controls.

One benefit/complication of co-transcriptomics is it takes a whole paper to describe one facet of the data. This complements a previous paper studying the Botrytis transcriptome across the same plant species. www.biorxiv.org/content/10.1...

We intentionally included 72 different Botrytis genotypes to ask how these patterns were or were not stable. Interestingly, each plant species differentiated between the isolates but in their own unique ways. Suggests that translating mechanisms across plants will need to focus on concepts (2/3)

Ever wondered if diverse plant species respond similarly when infected by the same exact pathogen? Infect different asterids and rosids with the same Botrytis genotypes and teh short answer, quite differently. www.biorxiv.org/content/10.6... @annajomu.bsky.social @ccaseys.bsky.social (1/3)
