Summary: In this study, a total of 293 putative AGP-encoding genes were identified in Brassica rapa, indicating a potential role of AGPs in plant growth and development, especially in male reproductive development. Additionally, three members of the FLA subfamily were found to play a key role in pollen germination process.

Summary: The responsiveness to environmental conditions and developmental plasticity of root systems are crucial for plant fitness, with AGPs playing an essential role at the cellular level in cell expansion, differentiation, root growth regulation, interactions with other organisms, and environmental responses. Despite the complexity of cell wall functional and regulatory networks, the exact molecular mechanisms of AGP-action remain largely unknown, as summarized in this evolving field of root biology.

Summary: In this study, members of the tomato FLA family were characterized and analyzed. The majority of these FLA members were highly expressed in roots and showed responsiveness to plant hormones ABA and MeJA. They also responded positively to salt, cold, and drought stress.

Summary: This study suggests that FLA11 and FLA12 may act as cell surface sensors in plant xylem cells, allowing them to sense mechanical stimuli and regulate secondary cell wall (SCW) development. Overexpression of FLA11 promotes earlier SCW development, while overexpression of FLA12 increases cellulose content. These proteins play a role in modulating SCW responses to mechanical stress.

Summary: This study reports a well-preserved skull and postcranium of the Middle Jurassic epoch (160 million years ago) haramiyidan Vilevolodon diplomylos, showing intact auditory ossicles. Comparing this fossil with other Mesozoic and extant mammals, the overlapping incudomallear articulation found in various groups of mammals is proposed to have evolved during the transition from dual to single function for the ossicles.

Summary: A new fossil dolphin, Nihohae matakoi gen. et sp. nov., from the Late Oligocene of New Zealand, reveals a diverse dentition with a variety of tooth shapes and orientations, including horizontally procumbent tusk-like teeth. This suggests adaptive advantages for horizontally procumbent teeth in basal dolphins.

Summary: This article reports on two fossil termite reproductive individuals with soldier-like heads and functional wings, suggesting the early occurrence of defensive features in termite evolution. The researchers discuss two possible scenarios for the origin of these individuals and their relation to the development of soldiers.

Summary: The role of glycoproteins in cell surface molecules during development and stress is important but poorly understood. FASCICLIN-LIKE ARABINOGALACTAN PROTEINs (FLAs) are a glycoprotein family that affects plant growth and development. They have complex structures comprising globular fasciclin-like (FAS1) domains, intrinsically disordered regions, and glycomotifs for directing glycan addition.

Summary: FLA18 plays a role in root elongation in Arabidopsis thaliana, with fla18 mutants exhibiting short and swollen lateral roots under high-sucrose conditions. Genetic interaction with sos5 results in more severe perturbation of anisotropic growth in both primary roots and lateral roots, while fla18sos5 shows a chlorotic shoot phenotype under salt-stress conditions.

Summary: This study reports the identification of a male-sterile mutant of DEFECTIVE EXINE AND APERTURE PATTERNING1 (DEAP1) in rice. DEAP1 is involved in rice pollen aperture development and may affect exine formation and aperture patterning, providing new insights into the molecular functions of plant FLAs in male fertility.

Summary: This study examined the flash signals and mate recognition in the Asian firefly, Aquatica lateralis, and found that the flash pattern of females changes after mating. The flashes of sedentary males, receptive females, and mated females could be differentiated based on flash duration and flicker intensity. Male attraction experiments showed that flying and sedentary males were attracted to flashes with shorter durations and lower flicker intensities. The findings suggest that flicker intensity is a mate recognition signal parameter in A. lateralis males.

Summary: This study identified 1858 expansin members in 40 plant species, classified into EXPA, EXPB, EXLA, and EXLB groups, with wheat containing 104 expansins. Phylogenetic analysis revealed high similarity between wheat, rice, and Arabidopsis expansins. Evolutionary analysis showed gene duplication, loss, and chromosomal rearrangement events in wheat expansins. Wheat expansin genes contain development, hormone, and abiotic stress related cis-elements, with their expression affected by environmental stresses. Overexpression of TaEXPB1A in Arabidopsis characterized its role in root and seed development, indicating the extensive functions of wheat expansins.
