Day 29 #SciArtSeptember prompt foresight: #botanist E.K. Janaki Ammal (1897-1984), here with plants she studied. 🐑πŸ§ͺπŸ‘©πŸΎβ€πŸ”¬ A trailblazer for #womenInSTEM in India, expert in cytogenetics, phytogeography, coauthor Chromosomal Atlas of Plants, 1st Indian woman PhD & early woman in US #botany PhD, 🧡
My linocut portrait of Janaki Ammal on speckled cream coloured washi paper, in purple ink, seated, in a sari and looking over her shoulder. There are mitosis diagrams on her sari. She is surrounded by plants she worked on: sugarcane in green to her left, magnolia with purple-brown branches and white blossoms outlined in silver to her right and a purple eggplant with pink blossom, and green leaves and stem at the bottom.

Shades of purple seen in flower this week near Peterborough - Bush Vetch at Rice Wood; Devil's-bit Scabious at Castor Hanglands NNR and Heather at Holme Fen NNR, where it grows on acid peat from a former raised bog. #wildflowerhour @bsbibotany.bsky.social
Purple pea flowers of Bush Vetch
Purple flowers of Devil's-bit Scabious, the only plant I could find flowering at Castor Hanglands, which once used to have a glorious show of this characteristic late-summer and autumn species
Heather still flowering well at Holme Fen NNR

Fascinating essay by @martinebotany.bsky.social on spiny solanums (tomato et al. relatives) as an example of all the important natural history research left to be done. Great observations on pollination and symbiosis... A very inspiring Sunday morning read! onlinelibrary.wiley.com/d….

"Close encounter" Hibiscus flower reproductive structures, in the early stage of maturation. #Flowers #BloomScrolling #Horticulture #Gardening #Botany #Macrophotography #SciArt #PhotoHour
Photo showing the reproductive structures of a Hibiscus flower. In the center of the photo, red fluffy globules are the stigmas, the part of the pistil that receives pollen for fertilization. All around them are multiple stamens, the parts of the flower that produce pollen. The stamens are distributed in 5 groups around the pistil style, in a vaguely star-shaped fashion. No pollen is yet visible on the anthers, the crescent-like structures on the tip of each stamen. Around this central structure, the corolla of the flower is visible as a dark orange blur.

Hema Sane, a botanist who lived without electricity, passed away on September 19th at the age of 85 in Pune, India. She taught botany for over six decades, authored over 30 books on Indian plants, and advocated for ecological consistency, rejecting modern conveniences.

In a crumbling four-story wada in Pune’s old quarter, an upstairs room stayed stubbornly off the grid. There, a small woman in a plain cotton sari wrote longhand by daylight or by kerosene lamp. This was Hema Sane, a botanist who turned her life into an experiment in ecological consistency.

Ipomoea (642 spp.) has a global distribution, especially in the tropics. Ipomoea pes-caprae is found on tropical beaches worldwide. Its seeds have air pockets under the thick, hard seed coat that allow them to float for months, possibly longer. #dispersal #Convolvulaceae #Botany 🌾πŸ§ͺ🌱

🧬🌽 RESEARCH 🧬🌽 🧬🌽 Genetic and transcriptome analyses of ZmNRL1, a DUF630 and DUF632 domains-containing protein, revealed its positive role in regulating the response of maize to nitrogen starvation – Zheng et al. πŸ”— doi.org/10.1093/jxb/... #PlantScience πŸ§ͺ
Fig. 1.GWAS of NUE-related traits in maize. (A) Representative images of contrasting growth phenotypes of four maize inbred lines under N-deficit conditions. Scale bars, 5β€…cm (top); 10β€…cm (bottom). (B) Analysis of total dry weight, chlorophyll content, nitrogen translocation in old leaves, and nitrogen translocation in young leaves from four maize inbred lines. Data show the means Β± SD. Statistical significance was determined by one-way ANOVA followed by Turkey multiple comparison test at a P-value < 0.05. (C) Manhattan plots of chlorophyll content and chlorophyll degradation rate. GWAS was performed in a natural population consisting of 296 maize inbred lines using a general linear model (GLM). The dashed line depicts the significance threshold (1.79 Γ— 10βˆ’6), and the dots above dashed lines represent significant association SNPs. (D) Quantile–quantile plots for chlorophyll content and chlorophyll degradation rate. (E) Manhattan plot of the Zm00001d01973 genomic region on chromosome 7.

πŸŒ±πŸ“– RESEARCH πŸŒ±πŸ“– Bascom et al. used CRIPSR/Cas9 to produce a septuple AUXIN RESPONSE FACTOR mutant in the model bryophyte Physcomitrium patens , revealing the developmental consequences of the complete loss of auxin-mediated gene activation πŸŒ±πŸ“– πŸ”— doi.org/10.1093/jxb/... #PlantScience πŸ§ͺ
Fig. 4.Model of auxin de-repression. When the auxin concentration in the nucleus is low (A), the effect of ARFas, as well as other non-ARF transcription factors, is limited by Aux/IAA-mediated recruitment of the TPL co-repressor, closing the locus. As auxin levels rise (B), AFBs ubiquitinate Aux/IAAs, thereby allowing all transcription factors to act on the locus. As a result, there is a significant difference in gene expression between baseline and auxin induction. In afb1,2,3,4 mutants (C), Aux/IAAs are not degraded, and therefore the promoter remains closed. In the iaa2mDII degron mutant (D), one of three Aux/IAAs is stabilized, thereby resulting in only partial promoter closure. In arfasept lines, Aux/IAAs are not recruited to the promoter. While gene expression remains diminished without activating ARFs, other non-ARF transcription factors are allowed to provide baseline gene expression. However, there is no auxin-mediated induction.
