“𝐀𝐧𝐚𝐭𝐨𝐦𝐲 𝐬𝐞𝐬𝐬𝐢𝐨𝐧 𝐨𝐟 𝐚 𝐭𝐫𝐞𝐞

🧩As I mentioned yesterday, plants are built of different building blocks depending on the species. Many of them are often the same, but look different.

🌳 Today you can see the different parts from which a poplar tree is built. The shape of the leaves can actually look very different depending on where the tree is grown & depending on the subspecies:

🌿 ☘More elongated for Populus trichocarpa, round for Populus tremula when grown in the field and like a reversed heart shape when grown in the greenhouse.

💡 That shows us that its worthy to do greenhouse studies as well as field trials.

☝️🏼 Before leaves turn into leaves, they are compressed in leaf buds, which also take a while until they are activated to fully flourish & open all their leaves.

🌸 Then we have the flowers, male and female flowers at different stages, which are essential for pollination and the survival of the species.

👀At the bottom you can see a wood section, a sucker, the roots and a seed of a Poplar tree.

🎨This compilation of illustrated elements of a poplar tree looks different to what I posted yesterday, so it was more difficult to write a cohesive story about it for me 😅.

🧬The purpose was to make them rearrangeable for my client as they wish, because the light green color was coded & connected to certain gene expression data.

👉🏼 If you are interested in this topic, you can have a look at their webpage where they are used here: https://lnkd.in/eSftcpAm
⭐️Did you know leaves can look different depending on where they are grown?⭐️

“Tradeoffs of crop domestication - better yield, less microbes ⚖️🌾

📚 In agriculture, domestication is the process of selection of the best trait with increased adaptation or acclimatization of the plant. Most domesticated crop species share common traits such as increased yield and seed size and decreased dormancy and seed shattering.

🦠 However, there is evidence that domestication processes have profoundly altered the interactions between plant hosts and associated microorganisms.

👨‍🌾 It has been shown that wild ancestors and primitive landraces of wheat, breadfruit, and maize can benefit more from mycorrhizal symbiosis. Studies on other plants species, including Arabidopsis, sugar beet, barley and lettuce also suggested that human-centered breeding led to compositional changes in root-associated microbiomes

🌱 Wild relative crops can be characterized by:
-> a better adaptation to environmental stresses,
-> a balanced growth–defense trade-off,
-> a rich associated microbiome,
-> BUT usually a lower yield.

🌾 Domesticated crops exhibit:
-> improved productivity,
-> BUT reduced stress resilience and ability to recruit plant-associated microbes.

🎯 Plant‐associated microbiomes have a great potential to improve plant resilience and yields in farming systems, thus the traits associated with the recruitment of specific consortia could be also promising targets in breeding programs.

🧩Depending on the plant species, plants have different building blocks that make up their overall anatomy.

🎨However, there are certain basics that most plants have & here I have illustrated those of the plant Arabidopsis thaliana for a client, oriented on the setup of the eFP Browser.

🟤You can see the different stages of seed development & the growing embryo inside.

〰️The siliques are the containers of those seeds & also go through a ripening process.

🌱 When the seed is mature, it germinates & a little seedling starts growing, with the two first leaves called cotyledons.

🌿 This seedling keeps on growing & producing more and more leaves & a nice vegetative rosette is built over time.

🌼 As soon as the plant has the right conditions & age, it will start growing a stem and flowers, which again will produce siliques with seeds inside, to ensure next generations.

♻️This is roughly the life cycle of an Arabidopsis plant. It usually takes ca three months, but if it is grown under short-day conditions & fewer light, it takes a bit longer to mature.

⭐️Which anatomy basic block of any plant do you find most fascinating?⭐️

“Catching the cellular waves 🦠🏄

🔬Cytoplasmic streaming is a common system of active intracellular transport, widely present in plant cells ranging from algae to flowering plants.

🦠 The process facilitates the transport and mixing of substances in large cells, as well as the reorganization of organelles.

🧬 It was demonstrated that cytoplasmic streaming is generated by the movement of organelle-associated myosin (motor proteins) along actin filaments (primary cytoskeletal component).

⏱️ Cytoplasmic streaming velocity varies among species and cell types, ranging from 1 to 70 μm per second.

⚡ It was demonstrated that cytoplasmic streaming plays a crucial role in cellular communication, facilitating plant reaction to environmental cues.
