We are evaluating dryland cotton production in Martin county, Texas, measuring cotton lint yield per unit of rainfall. Our goal is to collect rainfall data per 250 - 400 ha. Upon selection of a rainfall gauge, we realized that the cost of using, for example, a tipping bucket-type rain gauge would be too expensive and thus searched for an alternative method. We selected an all-in-one commercially available weather station;hereafter, referred to as a Personal Weather Station (PWS) that is both wireless and solar powered. Our objective was to evaluate average measurements of rainfall obtained with the PWS and to compare these to measurements obtained with an automatic weather station (AWS). For this purpose, we installed four PWS deployed within 20 m of the Plant Stress and Water conservation Meteorological Tower that was used as our AWS, located at USDA-ARS cropping Systems Research Laboratory, Lubbock, TX. In addition, we measured and compared hourly average values of short-wave irradiance (Rg), air temperature (Tair) and relative humidity (RH), and wind speed (WS), and calculated values of dewpoint temperature (Tdew). This comparison was done over a 242-day period (1 October 2022-31 May 2023) and results indicated that there was no statistical difference in measurements of rainfall between the PWS and AWS. Hourly average values of Rg measured with the PWS and AWS agreed on clear days, but PWS measurements were higher on cloudy days. There was no statistical difference between PWS and AWS hourly average measurements of Tair, RH, and calculated Tdew. Hourly average measurements of Rg and WS were more variable. We concluded that the PWS we selected will provide adequate values of rainfall and other weather variables to meet our goal of evaluating dryland cotton lint yield per unit rainfall.

Amyotrophic lateral sclerosis(ALS)is a fatal neurodegenerative disease characterized by progressive degeneration of motor neurons,and it demonstrates high clinical heterogeneity and complex genetic architecture.A variation within TRMT2B(c.1356G>T;p.K452N)was identified to be associated with ALS in a family comprising two patients with juvenile ALS(JALS).Two missense variations and one splicing variation were identified in 10 patients with ALS in a cohort with 910 patients with ALS,and three more variants were identified in a public ALS database including 3317 patients with ALS.A decreased number of mitochondria,swollen mitochondria,lower expression of ND1,decreased mitochondrial complex I activities,lower mitochondrial aerobic respiration,and a high level of ROS were observed functionally in patient-originated lymphoblastoid cell lines and TRMT2B interfering HEK293 ***,TRMT2B variations overexpression cells also displayed decreased *** conclusion,a novel JALS-associated gene called TRMT2B was identified,thus broadening the clinical and genetic spectrum of ALS.
