Genetic control of sweetness and acidity in blackberry

"Studies have shown that most consumers prefer sweet blackberries with relatively low acidity, but little research has been conducted to understand the genetic control of these traits in Rubus."

Which, I guess, is why commercial berries suck so much in taste compared to weed "Himalaya" blackberries.

Since I got a bunch of new follows recently, I wanted to give a picture of the kind of plant science work I've done.

My BA is in Art (awarded in the '80s). I went to community college in 2013 and ended up steering towards getting a Masters and eventual PhD in #PlantBreeding. Which meant a lot of re-upping of my science units & taking new science courses.

As an older disabled student, this was not an easy path and it took years, but I did eventually get to grad school & just got my Masters.

My dry loving and moisture loving transplants 🌿 are both doing really well but my mesic (neutral moisture) plants are struggling. It is likely that moisture loss and disease (seeing some of this) are main reasons why transplants fail. My experience is really exciting as logically it would make sense, because dry loving species are adapted to resist moisture loss while my moisture loving species are able to quickly uptake the water I am abundantly giving them. On the other hand, the 'middle ground' species appear to be struggling because they are neithier as efficient at uptake nor efficient at water conservation. Likely these are species that need to be transplanted in the off/late/early season. #PlantBreeding #NativePlants #ResorationEcology

Also the bunnies don't help but I have a hard time blaming them.

The source of many of my plant dreams these days are these apple seedlings. I got the seed from the inspiring Californian small-scale apple breeder Steven Edholm. Each container is either an open pollinated mix of summer, fall, winter apples or specific styles of apples like savory or red-fleshed apples. There's a few specific crosses, esp. of red-fleshed and highly aromatic apple varieties - some of them that are Edholm's own creations. I've grafted several of his new releases this year like BITE ME!, Amberwine, Black Strawberry, Cherub, Cherry Crush and Tomboy and plan on doing my own crosses too this year. Looking forward in anticipation to taste the fruits.

"Processing Maize Ears at the North Central Regional Plant Introduction Station"

This is an introduction to some of what they do maintaining maize agrobiodiversity. This work doing plant germplasm conservation is done by USDA as well as land grant universities in the US. The work was already underfunded before the recent changes.

Some pics of the perennial kale landrace I'm developing. Original seed came from Chris Homanics which I crossed with Daubenton for further bushy growth habit. There's probably also some other kale genetics in there by now. Have been growing it for 5-6 years or so at 4 different sites. This one is at the school. I love to go looking for new colors, shapes or particularly healthy individuals, esp. ability to survive the winters, slugs, birds and caterpillars. My goal is to adapt this landrace to my conditions and the tastes of local chefs. These are doing pretty well in February! #PerennialVegetables #PerennialKale #PlantBreeding #LandraceGardening #AdaptiveGardening #BrassicaOleracea

@ashinonyx My advisor was involved in some of this work as a grad student! nature.com/articles/nbt0588-55

It's funny, because he's really an old school pomology traditional breeder at heart (which is why we're a good match).

NatureFactors Influencing Gene Delivery into Zea Mays Cells by High–Velocity Microprojectiles - Nature BiotechnologyFactors influencing the efficiency of DNA delivery into suspension culture cells of Zea mays by the particle bombardment process were studied using a chimeric gene coding for the production of β–glucuronidase. Two days following bombardment with plasmid–coated microprojectiles, expression of the β–glucuronidase gene was detected with the synthetic substrate 5–bromo–4–chloro–3–indoyl–β–D–glucuronic acid, which, upon cleavage, forms a blue precipitate visually detectable within affected cells. The number of cells expressing β–glucuronidase was about 30 times greater when the cells were bombarded on a filter paper support than when they were bombarded while covered by liquid media without such a support. The efficiency of gene delivery was also significantly affected by the velocity of the microprojectile and the number of micro–projectiles used for bombardment, and the concentration of CaCl2 and spermidine used to adsorb DNA to the microprojectiles. In addition to cell cultures, the particle bombardment process was also used to deliver the β–glucuronidase gene to intact cells on the surface of excised Z. mays embryos. The results indicate that delivery by high–velocity microprojectiles may be useful for the stable transformation of monocot species.
