Article Synopsis
- The endosperm in maize kernels is essential for embryo development and germination, with transfer cells at the base playing a key role in nutrient transport and defense against pathogens.
- A study identified the ZmMYBR29 transcription factor, which is specifically expressed in the basal endosperm and was shown to impact kernel size and grain filling rate when mutated.
- The findings suggest that ZmMYBR29 influences kernel weight by regulating genes involved in starch synthesis and carbohydrate metabolism, highlighting its significance in maize endosperm development.
The mitochondrion is a semi-autonomous organelle that provides energy for cell activities through oxidative phosphorylation. In this study, we identified a defective kernel 66 (dek66)-mutant maize with defective kernels. We characterized a candidate gene, DEK66, encoding a ribosomal assembly factor located in mitochondria and possessing GTPase activity (which belongs to the ribosome biogenesis GTPase A family).

A deep reinforcement learning (DRL)-based assistive guiding robot with ultrawide-bandwidth (UWB) beacons that can navigate through routes with designated waypoints was designed in this study. Typically, a simultaneous localization and mapping (SLAM) framework is used to estimate the robot pose and navigational goal; however, SLAM frameworks are vulnerable in certain dynamic environments.

- Nitrogen is crucial for plant growth, with nitrate being a key form used by plants; however, its role in seed development is still not fully understood.
- Researchers focused on the maize mutant zmnpf7.9, identifying the ZmNPF7.9 gene, responsible for nitrate transport in the plant, which is vital for endosperm development.
- The study shows that when ZmNPF7.9 is dysfunctional, it leads to delayed seed development and a reduction in grain weight, indicating its importance in nutrient delivery and metabolism during the seed development process.
Transformation of perfluorooctane sulfonate (PFOS) precursors (PreFOSs) is considered an additional source of PFOS in the environment and biota. A PreFOSs-degrading bacterium PF1, which was able to utilize PreFOSs as the sole carbon and energy source for growth, was isolated from contaminated soil collected from the surroundings of a fluoride factory. According to its morphology and 16S rDNA gene sequence analysis, strain PF1 was identified as sp.

Expression of this gene in flowers appears to be correlated with calyx persistence. Korla fragrant pear (Pyrus brestschneideri Rehd) is an economically important pear cultivar in China.
