Summary: Insect pollinators like the tobacco hawkmoth have olfactory sensilla not just on their antennae but also at the tip of their proboscis. While moths can easily learn odors with their antennae, solely perceiving odors with the proboscis is not enough for odor learning. There appears to be no communication between the antennae and proboscis, and information learned by the antennae cannot be recalled by the proboscis.

Summary: Most C4 plants in tropical or subtropical climates have evolved adaptations to grow in high light environments. These adaptations ensure balanced energy distribution, counteract photoinhibition, and dissipate excess light energy. Effective electron transport in photosynthesis leads to the production of NADPH and ATP, which are necessary for C4 metabolism and CO2 assimilation. Different metabolic subtypes of C4 plants may have variations in the mechanisms occurring in mesophyll and bundle sheath chloroplasts, indicating plasticity in energy utilization pathways.

Summary: Plants use limited resources to produce toxic defenses in response to challenges from herbivores and competitors. Jasmonate signaling, mediated by MYC2 transcription factors, helps reconfigure metabolism to minimize defense costs and optimize fitness in complex environments. In this study, NaMYC2a/b genes were silenced in Nicotiana attenuata, resulting in higher growth and fitness in environments with reduced herbivores but lower fitness in high herbivore-load environments. The presence of competitors and mobile herbivores led to lower fitness in single-genotype setups but increased fitness in mixed-genotype setups. MYC2 TFs play a crucial role in the reconfiguration of primary and specialized metabolism for plants to optimize their fitness in complex environments.

Summary: Hydroxy- and carboxyblumenol C-glucosides specifically accumulate in roots and leaves of plants harboring arbuscular mycorrhizal fungi (AMF). Silencing the key gene CCD1 in blumenol biosynthesis resulted in changes in blumenol and AMF-specific lipid accumulations, and the relationship between them. Blumenol accumulations reflect plant fitness when grown in isolation, but predict fitness outcomes when grown with competitors.

Summary: Plants produce chemical defenses to poison or deter insect herbivores, but these defenses may also affect the beneficial endosymbionts of the herbivores. This study found that rice produces an antifungal flavonoid phytoalexin in response to attack by a pest, which inhibits the pest's beneficial endosymbionts.

Summary: Plants interact with arbuscular mycorrhizal fungi (AMF) and alter the expression of miRNAs and their targets. The role of an Argonaute protein in regulating this interaction remains unknown. In this study, the silencing of NaAGO7 reduced the competitive ability of plants under low-P conditions without affecting their development. The roots of NaAGO7-silenced plants were over-colonized with AMF but accumulated less phosphate, and the expression of AMF-specific transporters was deregulated. Overexpression of certain miRNAs decreased plant fitness and downregulated targets in GA, ethylene, and fatty acid metabolism pathways.

Summary: Plant defense against herbivores is costly and often leads to growth repression. The phytohormone jasmonate (JA) plays a key role in prioritizing defense over growth during herbivore attack, but the mechanisms are not well understood. This study demonstrates that JA signaling enhances gibberellin (GA) catabolism mediated by GA2ox enzymes, resulting in growth inhibition in rice plants attacked by brown planthoppers (BPH). JA signaling activates defense responses and GA catabolism concurrently, optimizing resource allocation in attacked plants and providing a mechanism for phytohormone crosstalk.

Summary: ABCA1 transporter was found to be associated with the progression and prognosis of melanoma. Depletion or inhibition of ABCA1 affected the invasion capacities of melanoma cells and disrupted active focal adhesion formation. Additionally, ABCA1 regulated the lateral organization of the plasma membrane in melanoma cells. These findings suggest that ABCA1 may contribute to tumor progression and poor prognosis in melanoma, highlighting its potential as a metastatic marker.
