Pollen hydration, germination, and tube growth are vital processes that involve complex signaling pathways. Here, Kim et al report that OsPRK1/2/3-mediated #ROS signaling is required for #pollen tube #germination in #rice

ROPs & ROPGEFs are essential for initiating polar growth in plants, but which ones activate #pollen #germination? This study reveals polarization of specific #ROPGEFs, identifying special roles for ROPGEF8 & ROPGEF9 in germination @PLOSBiology https://plos.io/3S4rV2d
Might be a little late, but I'm getting the few seedlings starting to germinate that I can for ETX community garden! 🌱

Seedlings doing well, and more seeds sown. Still a risk of frost.

They looked so manky and worm-eaten* but clearly they want to grow up to become giant beans?

"Peas are good tonight, dear."
Germination achieved for 'Mikado' (a potato-leaved heirloom and possible ancestor of 'Brandywine'), 'Honey Drop' (an open-pollinated yellow cherry touted as tasting like white grapes), and 'San Marzano' (a plum choice for canning). #tomatoes #garden #gardening #seedlings #germination #vegetables #allotment
Let's plant some seeds!
#Germination nation!
Because sometimes seeing is believing, here are my seeds, placed in a small plastic bag and juice box. #germination #gardening #plants #food #tomato #peppers #garden #Summer2025

Waiting for seeds to germinate is like …
Come on! Come on! I’m waiting!
The seeds say:
We’ll come when we’re good and ready and not a moment sooner
Soil salinity impacts rice seed germination, severely limiting #CropYield. Using chemical mutagenesis, Zeng et al. identify rice #germination defective #mutant OsHAK9 that regulates #seed germination under #salt stress. 🔓⬇️
