Differential expression of flavonoid biosynthetic pathway genes drives the production of transgressive pigments in #Nicotiana section Repandae allotetraploids

New #AJB research by @emccnicotiana.bsky.social, @jlandisbotany.bsky.social, et al.

doi.org/10.1002/ajb2... #botany #polyploidy
Front, side, and dissected view photographs of anthesis flowers from Nicotiana section Repandae allopolyploids (N. nudicaulis, N. repanda, and N. stocktonii) and their diploid progenitors N. sylvestris and N. obtusifolia. Nicotiana nudicaulis also has side view flower bud photographs at Stage 1, Stage 2, and Stage 3, which represent 60%, 85%, and 95% of anthesis length, respectively. Nicotiana nudicaulis and N. repanda have transgressive delphinidin pigmentation not found in either progenitor.

One of my favourites, it took two vacations in the French alps to find these beauties. Bombus Brodmannicus, a specialized bumblebee dependend on Cerinthe. This was 2023 July.
Mind: running on a slope diving low to shoot the bees hanging under low flowers being very shy 😍 Very Mindful activity.

New #mimulus preprint! We found grandparental environments exhibit strong effects on the fitness of their grand-offspring and whether this was positive or negative depended on the historical environment, showing TGP is locally adaptive

Transgenerational plasticity affects fitness and mediates local adaptation
Transgenerational plasticity (TGP) could be as decisive of a factor in phenotypic outcomes as allelic variation and within-generation plasticity. While TGP is often associated with priming offspring t...

How fast do plants actually grow? And which growth processes matter most for organ size?
We dived into 176 papers, extracted and re-analyzed the data so you don’t have to!

I’m so proud of my grad student @evoyeyo.bsky.social for defending his @lsubiosci.bsky.social PhD thesis on macroevolution of #Brachyotum and the broader Andean flora today. Felicidades, Dr. Paredes-Burneo!! ⛰️🧬🌻🥳👨🏽‍🎓🇵🇪
Diego and I posing next to each other after his defense in the LSU herbarium. Diego in front of a slide that says “Plant evolution in the Andes is more complex than current phylogenomic models can explain” with lots of pretty plant photos around the text. A celebration in Diego’s honor in the LSU herbarium. Diego, family, me and other close friends celebrate at dinner.

Excited to share this work, out today in MBE! In polar fishes, we found that antifreeze protein genes expanded in copy number at low temperatures and contracted in the deep sea, highlighting a role of depth and pressure in AFP evolution.

The global whaling industry experienced a boom c. 1840-1950 as technology allowed whalers to hunt the Southern Ocean around Antarctica.

Under standard models, we would have expected krill populations to have *exploded*.

Instead, they DROPPED exponentially.

Let's talk about the KRILL PARADOX.
Change in distribution and abundance of southern right whales. (A) Shows historical and contemporary wintering distributions (Figure 1 from Carroll et al., 2018), and (B) shows decline in abundance and subsequent recovery (solid line is the mean, dashed line shows upper and lower 95% CI). Modified Figure 1 from Jackson et al. (2008). Contemporary sightings are divided into regions where large aggregations are seen during winter: Argentina (ARG), Brazil (BZL), South Africa (SAF), southwest Australia (SWA), south central Australia (SCA), and New Zealand sub-Antarctic (NZSA) and regions where sightings are typically of small numbers of individuals per year. The large aggregations are IWC management units and correspond to historical whaling grounds, although another 5 whaling grounds show little sign of recovery. Summer feeding areas are poorly described and so not shown.
