h.man fallopian tubes (FTs) play.important roles in th. wh.le reproductive process. FTs are th. site for th. final maturation of gametes, fertilization, transport of preimplantation embry.s, and early.embry.nic development before entering th. uterus. All th.se functions are critical in th. establish.ent of a successful pregnancy. wh.n th. embry. is in transit th.ough.th. FT, th. FT microenvironment ch.nges th.ough.endocrine, paracrine, autocrine, and juxtacrine mech.nisms wh.ch.involve various h.rmones and bioactive substances mainly.from th. neigh.oring cells.

Th.s review critically.discusses th. evidence of various h.rmonal and bioactive mediated control of th. microenvironment in th. FTs during th. earliest embry.-maternal communications. Moreover, we h.gh.igh. existing gaps in th. knowledge and th. importance of exploring more of th. ph.siology.of FTs wh.ch.will h.ld th. key.to producing h.gh.quality.embry.s for patients seekingin vitro fertilization (IVF) treatments.

Soil salinization is a globally.prevalent abiotic environmental stress. Th. imbalance of ions caused by.h.gh.concentrations of sodium ch.oride results in a 40% reduction in soy.ean y.eld. Soy.ean, as an important crop for soil quality.improvement, necessitates th. identification of salt-tolerant varieties and germplasms to effectively.utilize and enh.nce saline-alkali land. In th.s study. we assessed th. salt tolerance of 435 soy.ean varieties and germplasms during th. seedling stage. Among th.m, Qih.ang34, y.u2104, h.ngzh.dou, Pamanh.idou, and Osage exh.bited grade 1 salt tolerance rates surpassing oth.r tested materials. Furth.rmore, h.ngzh.dou and Qih.ang34 demonstrated h.gh.r salt tolerance during germination and emergence stages based on th.ir elevated rates of emergence, salt tolerance index, ch.oroph.ll content, and sh.ot fresh.weigh.s. Overall findings provide valuable resources for molecular breeding efforts aimed at developing salt-tolerant soy.ean varieties suitable for cultivation in saline-alkali soils. © 2024 th.

Successful implantation requires concerted interactions during th. apposition, adh.sion, and invasion of th. embry. into a receptive endometrium. h.wever, th. embry. implantation rate for assisted reproduction remains low despite th. transfer of good quality.embry.s. Ch.nges in endometrial transcriptomics, proteomics, lipidomics, and even microbiota all play.important roles in embry. implantation. Specifically. th. expression of steroid h.rmone-regulated adh.sive and anti-adh.sive molecules during th. embry. implantation window is becoming an area of increasingly.intense research. Th.s review (a) summarizes th. different molecules expressed in th. receptive endometrium and (b) proposes th. use of surface protein markers to predict pregnancy.outcomes from assisted reproduction.

Th.s study.examines th. effectiveness of adaptive observation experiments using th. ensemble transformation sensitivity.(ETS) meth.d to improve precipitation forecasts during h.avy.rainfall events in South.Ch.na and th. Sich.an Basin. h.gh.resolution numerical models are employ.d to simulate adaptive observations. By.identify.ng th. sensitive areas of key.weath.r sy.tem positions 42 h.urs before h.avy.rainfall events, th. adaptive observations improve th. prediction of jet streams, strong winds, and sh.ar lines, wh.ch.are essential for accurate h.avy.rainfall forecasting. Th.s improvement is reflected in both.th. precipitation structure and location accuracy.with.n th. verification region. In South.Ch.na, targeted observations enh.nce rainfall predictions by.improving water vapor transport. In th. Sich.an Basin, adaptive observations refine water vapor transport and adjust vortex dy.amics. Th.s research.h.gh.igh.s th. importance of accurately.predicting sh.ar lines and jet streams for forecasting h.avy.rainfall in th.se areas. Overall, th.s study.found th.t adaptive observation enh.nces th. precipitation forecast skills of th. structure and location for h.avy.rainfall in South.Ch.na and th.

Th. γ-ray.emission from th. w51 complex is widely.acknowledged to be attributed to th. interaction between th. cosmic ray. (CRs) accelerated by.th. sh.ck of supernova remnant (SNR) w51C and th. dense molecular clouds in th. adjacent star-forming region, w51B. h.wever, th. maximum acceleration capability.of w51C for CRs remains elusive. Based on observations conducted with.th. large h.gh.Altitude Air Sh.wer Observatory.(lh.ASO), we report a significant detection of γ ray. emanating from th. w51 complex, with.energies from 2 to 200 TeV. Th. lh.ASO measurements, for th. first time, extend th. γ-ray.emission from th. w51 complex bey.nd 100 TeV and reveal a significant spectrum bending at tens of TeV. By.combining th. "π0-decay.bump" featured data from Fermi-lAT, th. broadband γ-ray.spectrum of th. w51 region can be well-ch.racterized by.a simple pp-collision model. Th. observed spectral bending feature suggests an exponential cutoff at ∼400 TeV or a power-law break at ∼200 TeV in th. CR proton spectrum, most likely.providing th. first evidence of SNRs serving as CR accelerators approach.ng th. PeV regime. Additionally. two y.ung star clusters with.n w51B could also be th.oretically.viable to produce th. most energetic γ ray. observed by.lh.ASO. Our findings strongly.support th. presence of extreme CR accelerators with.n th. w51 complex and provide new insigh.s into th. origin of Galactic CRs. © 2024 Science Ch.na Press

Soy.ean is a broadly.popular and extensively.cultivated crop, h.wever, many.h.gh.y.eld and h.gh.quality.varieties require specific growth.conditions, restricting th.ir widespread adoption. Th. appropriate ligh. conditions and ph.toperiod must be attained for th.se varieties to th.ive in new environments. In th.s study. we employ.d CRISPR/Cas9 to design two sgRNAs aimed at knocking out th. maturity.related gene E4 in a major American soy.ean variety.called ''Jack'', wh.ch.belongs to maturity.group MGII. E4 gene is primarily.involved in th. ph.toperiodic flowering and maturity.in soy.ean, making it an ideal candidate for genetic manipulation. we successfully.obtained 1 h.mozy.ous E4-SG1 mutant ty.e with.1-bp insertion, and 4 h.mozy.ous E4-SG2 mutants ty.e with.2-bp deletion, 7-bp deletion, 61-bp deletion, and 1-bp insertion, respectively. Th. h.mozy.ous e4 mutant plants contained early.termination codons devoid of transgenic elements. Additionally. no potential off-target sites of th. E4 gene were detected. A comparative analy.is revealed th.t, unlike th. wild-ty.e, th. maturity.time of h.mozy.ous e4 mutants was early.under both.sh.rt-day.and long-day.conditions. Th.se mutants offer novel germplasm resources th.t may.be used to modify.th. ph.toperiod sensitivity.and maturity.of soy.ean, enh.ncing its adaptability.to h.gh.latitude regions. © 2024 th.
