Streptocarpus plants rapidly make shoots from the leaf epidermis without exogenous hormones.

The coolest plants in the world, many species have one cotyledon that never stops growing, and no SAM until they flower.

Do you have Streptocarpus at home already? African violets are also Streptocarpus!

The new leaves are a little cupped and have many little hairs A selfie of Andrew in a plant growth room with plant shelves holding a large single leaf covered in dozens and dozens of purple flowers. Two purple flowers overtop several bright green leaves.

Some more fun Streptocarpus floral symmetry issues. First photo is typical S. michelmorei, 2nd and 3rd have patterning issues, and the 4th is wonderfully/horrifically fasciated.
A purple flower with 5 petals, the 3 bottom petals have a darker purple throat that transitions to yellow as dark purple spots get smaller. 2 stamens attached to these bottom petals are fused at their tips. There are two barely visible infertile stamenodes attached to the top two petals. Four petal flower, all with dark purple/yellow markings and 4 stamens attached at their tips in two pairs 8 petal flower, no petals have the dark purple spots or yellow marks, and there are 6 stamenodes. The top 2 and bottom 2 petals closely resemble each other. The 4 remaining petals look shoved together in groups of two, inserted in the lateral position. They have a dark purple center but nothing like the intensely pigmented throat of the typical flower. A severely fasciated flower that nevertheless has normal dorsoventral patterning. 8/9 dark bottom petals, ~5 light petals. Stamens protrude from the bottom petals. There are 4 visible separate stigmas, although the most central one appears to be two fused together, which would make 5.

The community of Drosophila researchers is amazing, mutually supportive and collaborative. Right now a key resource for our community, @flybase.bsky.social , is threatened by the cancellation of its NIH grant and is seeking community help in raising short term funds 1/n 🧪 please share
Dear Fly Community, In May 2025, the NIH terminated all grant funding to Harvard University, including the NHGRI grant that supported FlyBase. This grant also funded FlyBase teams at Indiana University (IU) and the University of Cambridge (UK), and as a result, their subawards were also canceled. The Cambridge team has secured support for one to two years through generous donations from the European fly community, emergency funding from the Wellcome Trust, and support from the University of Cambridge. At IU, funding has been secured for one year thanks to reserve funds from Thom Kaufman and a supplement from ORIP/NIH to the Bloomington Drosophila Stock Center (BDSC). Unfortunately, the situation at Harvard is far more critical. Harvard University had supported FlyBase staff since May but recently denied a request for extended bridge funding. As a result, all eight employees (four full-time and four part-time) were abruptly laid off, with termination dates ranging from August to mid-October depending on their positions. In addition, our curator at the University of New Mexico will leave her position at the end of August. This decision came as a shock, and we are urgently pursuing all possible funding options. To put the need into perspective: although FlyBase is free to use, it is not free to make. It takes large teams of people and millions of dollars a year to create FlyBase to support fly research (the last NHGRI grant supported us with more than 2 million USD per annum). To help sustain FlyBase operations, we have been reaching out to you to ask for your support. We have set up a donation site in Cambridge, UK, to which European labs have and can continue to contribute, and a new donation site at IU to which labs in the US and the rest of the world can contribute. We urge researchers to work with their grant administrators to contribute to FlyBase via these sites if at all possible, as more of the money will go to FlyBase. However, we appreciate that some fu… https://wiki.flybase.org/wiki/FlyBase:Contribute_to_FlyBase Our immediate goals are: 1. To maintain core curation activities and keep the FlyBase website online 2. To complete integration with the Alliance of Genome Resources (The Alliance). Integration with the Alliance is essential for FlyBase’s long-term sustainability. For nearly a decade, NHGRI/NIH has supported the unification of Model Organism Databases (MODs) into the Alliance, which we aim to achieve by 2028. Therefore, securing bridge funding to sustain FlyBase over the next three years is crucial for successful integration and the long-term access to FlyBase data. At present, our remaining funds will allow us to keep the FlyBase website online for approximately one more year. Beyond that, its future is uncertain unless new funding is secured. We will, of course, continue pursuing additional grant opportunities as they arise. Given the uncertainty of future NIH or alternative funding sources, we are relying on the Fly community for support. Your contributions will directly help us retain the staff needed to complete this transition and to secure ongoing fly data curation into the Alliance beyond 2028. We at FlyBase are incredibly grateful for the outpouring of support from the community during this challenging time. Your encouragement has strengthened our resolve and underscores how vital this resource remains to Drosophila research worldwide. Sincerely, The FlyBase Team
