The Asian icefish, Protosalanx chinensis, has undergone extensive colonization in various waters across China for decades due to its ecological and physiological significance as well as its economic importance in the fishery resource. Here, we decoded a telomere-to-telomere (T2T) genome for P. chinensis combining PacBio HiFi long reads and ultra-long ONT (nanopore) reads and Hi-C data.

The Mimosa pudica leaf has motor organs allowing movements driven by cell osmotic changes in the parenchyma cells in response to various stimuli. Short white light pulses induce rapid and large seismonastic-like movements (denoted "photostimulation") of the primary pulvini in various leaves within 120 s after the onset of light. An early event recorded is a wavelength-related modification of the plasma membrane difference: potential depolarization under white, blue, green, and red wavelengths, and hyperpolarization under far red wavelengths (and also in darkness).

Article Synopsis
- - GIGANTEA (GI) is a versatile plant protein derived from a common ancestor, playing essential roles in regulating various biological functions such as circadian rhythms, light responses, and stress management.
- - Despite being discovered over sixty years ago, the specific functional domains and mechanisms of action for GI remain largely undefined, prompting ongoing research into its evolutionary adaptation and integration into existing signaling pathways.
- - This review summarizes the known functions of GI while also exploring its evolutionary development within plant lineages, highlighting its emerging roles in chloroplast accumulation and anthocyanin production.
Biological characteristics of Leersia japonica (Makino) Honda and its implications for weed management.

Eco-Environmental Protection Research Institute, Shanghai Academy of Agricultural Sciences, Shanghai, China.
Background: Leersia japonica (Makino) Honda is a perennial weed and currently identified as a new dominant weed species in rice fields in many countries, including China. Here, we studied the biological characteristics combined with nonchemical management of L. japonica to develop a proper control strategy of this weed.

Salt stress is a recognized annihilating abiotic stress that has a significant impact on agricultural and horticulture crop productivity. Plant development faces three distinct dangers as a result of salt stress: oxidative stress, osmotic stress, and ionic toxicity. It has been shown that plants can forecast diurnal patterns using the circadian clock; moreover, they can manage their defensive mechanism for the detoxification of reactive oxygen species (ROS).
