Effects of Continuous and Split Developmental Photophases During Each 24 Hour Period on Adult Morphology in \u3ci\u3eEuschistus Tristigmus Tristigmus\u3c/i\u3e (Hemiptera: Pentatomidae) [PDF]

open access: yes, 2017
Rearing immatures of Euschistus tristigmus tristigmus in 8L:16D, 8L: 4D:8L;4D, and 16L:8D showed that the length of each photophase, rather than an accumulated total of shorter photophases, during each 24 hr period was the determining factor in producing

Quantitative Trait Loci for Thermal Time to Flowering and Photoperiod Responsiveness Discovered in Summer Annual-Type Brassica napus L

open access: yesPLoS ONE, 2014
Time of flowering is a key adaptive trait in plants and is conditioned by the interaction of genes and environmental cues including length of photoperiod, ambient temperature and vernalisation.

In-vitro proliferation of Musa balbisiana improves with increased vitamin concentration and dark culturing [PDF]

open access: yes, 2015
Musa balbisiana is a wild banana genotype with important traits such as drought tolerance and disease resistance. Uniform and clean plants are often required to study these traits in different laboratories but plants can only be generated through a ...

Effect of prepartum photoperiod and melatonin feeding on milk production and prolactin concentration in dairy heifers and cows.

open access: yesJournal of Dairy Science, 2014
Holstein multiparous cows (n = 29) and primiparous heifers (n = 32) calving over a 1-yr period were subjected to photoperiod-melatonin treatments according to a 2 × 3 factorial design.

An analysis of contractile and protrusive cell behaviors at the superficial surface of the zebrafish neural plate

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The forces underlying convergence and internalization of the teleost neural plate remain unknown. To help understand this morphogenesis, we analyzed collective and individual cell behaviors at the superficial surface of the neural plate as internalization begins to form the neural keel in the hindbrain region of the zebrafish embryo.

Squamate ventricular cardiomyocytes: Ploidy, proliferation, and heart muscle cell size in the leopard gecko (Eublepharis macularius)

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background While heart function is broadly conserved across vertebrates, the cellular phenotype of muscle cells (cardiomyocytes) varies across taxa and throughout ontogeny. Emerging evidence suggests that some attributes may correlate with the capacity for spontaneous cardiomyocyte replacement following injury.

Myomaker and Myomixer are required for craniofacial myoblast fusion in zebrafish

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Craniofacial and trunk skeletal muscles are derived from different progenitor populations during development. Trunk skeletal muscles contain mostly multinucleated myofibers that are formed through myoblast fusion. However, myoblast fusion in craniofacial muscles and its molecular regulation are not well understood.

Effect of accumulated duration of the light period on bud burst in Norway spruce (Picea abies) of varying ages

open access: yesSilva Fennica, 2001
One-year-old seedlings (two sowing times), two-year-old seedlings and 14- and 18-year-old cuttings of Norway spruce (Picea abies (L.) Karst.) were exposed to shortening photoperiod (initially 16 h), lengthening photoperiod (initially 6 h) and constant
