Abstract Soybean, a short‐day plant, has its origin in higher latitudes of China, and commercial cultivation remained confined to areas >22°N till 1970s due precocious flowering accompanied with reduced biomass lower latitudes. This review summarizes the effect short days on soybean phenology, discovery novel long juvenile (LJ) trait, role breaking latitudinal boundary for production, identi...

Citrus is a highly valued tree crop worldwide, while, at the same time, citrus production faces many biotic challenges, including bacterial canker and Huanglongbing (HLB). Breeding for disease-resistant varieties is the most efficient and sustainable approach to control plant diseases. Traditional breeding of citrus varieties is challenging due to multiple limitations, including polyploidy, pol...

Despite substantial heritability in pubertal development, much variation remains to be explained, leaving room for the influence of environmental factors to adjust its phenotypic trajectory in the service of fitness goals. Utilizing evolutionary development biology (evo-devo), we examine adolescence as an evolutionary life-history stage in its developmental context. We show that the transition ...

Shoot apical meristem (SAM) domes derived from five different outdoor and in vitro sources of juvenile and mature Eucalyptus urophylla x Eucalyptus grandis akin genotypes were compared. Overall measurements of SAM dome height H and diameter D ranged from 2 to 35 μm and 20 to 80 μm, notwithstanding significant differences according to the various physiological origins of plant material investiga...

Ab&act The structural performance of medium density fiberboard (MDF) is attributable to three primary variables which are: physical and mechanical properties of individual wood fibers; fiber-to-fiber stress transfer; and fiber orientation. These origins of fiber properties and stress transfer can be traced to the fiber generation method wherein fiber orientation is associated with mat formation...

Early life adversity (ELA) can lead to poor health later in life. However, there is significant variation in outcomes, with some individuals displaying resilience even in the face of adversity. Using longitudinal data collected from free-ranging rhesus macaques between birth and 3 years, we examined whether individual variation in vigilance for threat, an early emerging attentional bias, can ac...

Provisioning of juveniles is a defining characteristic of human life history. Human children are also unusual in cooperating with their siblings, mothers and other adults in the exchange of resources and labor. This article highlights this distinctly human and twofold nature of juvenility within the context of life history evolution and cooperative breeding. Juveniles benefit from continued inv...
