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.

花煙草（ハナタバコ）
別名 ニコチアナ、宿根煙草
ブラジル🇧🇷原産で一年草とされているが、強い霜の降りない地方では、越冬して灌木状になることもある。こちらは花を観賞するために誕生した園芸種で、私たちが思い浮かべるタバコは、葉タバコ（Nicotiana tabacum）の方になる。

Nicotiana White Trumpets in a UK garden.
Those Nicotiana White Trumpets are having an August moment in my garden. They're taller than me! The moths love them! #nicotiana #ukgardening

Happy Saturday 🌞
I have no idea how this Nicotiana got so big, but I like it. Very fragrant as well.
Happy Gardening everyone 🌱

Happy Tuesday 🌞
Pretty little flowers blooming from the Nicotiana or Flowering Tobacco.
Fabulous pink colour, which seems to be a bit of a theme in the garden this year.
Happy Gardening 🌱

1-2 inch star shaped blooms on approximately 24 inch tall foliage. Blooms are highly fragrant, with their sweet smell becoming more penetrating in the cool evenings.

Spent today potting on Nicotiana 'White Trumpets', partly for the Sparsholt College summer display by students but also to create a moth banquet in my front border. It's going to smell FABULOUS!! #nicotiana #ukgardening #horticulture #ukhorticulture #rhslevel2

These are one of my all time favourite flowers and I have them in a lovely square slate planter. Can't wait for July/August! 🌱

Figure 7. Target of Rapamycin (TOR) kinase is a positive regulator of plant fatty acid and lipid synthesis. Plant TOR is activated by light and sugars. Once activated, TOR positively regulates fatty acid (FA) and lipid synthesis by upregulating genes involved in de novo fatty acid synthesis and downregulating genes associated with lipid turnover. Additionally, TOR promotes the biosynthesis of proteins, cell walls, DNA, RNA, and the other essential cellular components. TOR complex shown in the figure is comprising of LST8-1 (Lethal with SEC13 protein 8-1, in green), TOR (in purple) and RAPTOR1B (Regulatory-associated protein of TOR 1B, in yellow) and its 3D structure model is predicated by AlphaFold 3.
Figure 1. Transient expression of TOR in Nicotiana benthamiana (N. benth) leaves increases the levels of total fatty acids (TFAs). A) Representative fluorescence confocal image of N. benth leaf samples taken 4 days after agroinfiltration with TOR-GFP. Bar = 50 µm. B) Immunoblotting with anti-GFP antibody shows TOR-GFP is detected in protein samples extracted from N. benth leaves 4 days after infiltration with agrobacterium containing plasmid TOR/pCHF3-hGFP (TOR-GFP), but not pCHF3-hGFP (Empty vector, EV). Ponceau S staining of PVDF membrane after protein transfer is shown as a protein loading control. M, protein markers. Multiple lanes for the same construct represent biological replicates. C) Transient expression of TOR for 4 days after agroinfiltration significantly elevates total fatty acids content in N. benth leaves after. Bar values represent mean ± SD (n = 6), with each data point represented by a dot. Asterisks denote a statistically difference from the EV (Student's t-test, **, P < 0.01).
Figure 5. Suppression of TOR activity by Torin 2 in a Brassica napus suspension cell culture results in significant reduction in the accumulation of both total fatty acid (TFA) and triacylglycerol (TAG). A) TFA content in Brassica napus microspore-derived suspension cells cultured in medium supplemented without (−) or with (+) 1 μM Torin 2 for the indicated time periods. B) TAG content in the Brassica napus suspension cells in (A). In this figure, bar values represent mean ± SD (n = 4), with each data point represented by a dot. Asterisks denote statistically significant differences from the non-Torin 2 treatment controls (Student’s t-test, *, P < 0.05; ***, P < 0.001).
Great work by Liu et al. (2024) on how #PlantTOR kinase positively regulates plant #FattyAcid and lipid synthesis in #Nicotiana benthamiana leaves 🍃, #Arabidopsis seedlings 🌱 and #Brassica napus suspension cells.
PS. Relatively short periods were used for the assays.

Luiz A. Cruz-Santos follows at #SOL2024 with a presentation about drought adaptation in the #Nicotiana Suaveolentes clade. Around 69 species have been described in this lineage. The ancestor of Australian nicotianas arrived to Pilbara mora than 2 MYA, an extremely drought region.
