To solve a problem, three things are necessary: awareness, means, and will. The 2015 COP21 Paris accord was a masterful, perhaps even world-saving, diplomatic advance toward making the world aware of climate change. Some of that success may have been

The segregation pattern of an 810-bp random amplified polymorphic DNA (RAPD) band in the F1 and backcross generations of a Silene dioica (L.) Clairv. family provides evidence that this molecular marker is located in the pseudoautosomal region (PAR) o

Sex determination in plants has been most thoroughly investigated in Silene latifolia, a dioecious species possessing heteromorphic sex chromosomes. We have identified several new Y chromosome linked RAPD markers and converted these to more reliable

Oenothera villaricae Dietrich and Oe. picensis Dietrich, complete translocation heterozygotes, are fully interfertile, giving rise to six discrete classes of true-breeding hybrids from a reciprocal cross. Associated with each parent and hybrid is a c

A series of studies, recently reviewed, has established that approximately 60% of the structural genes which are expressed in the sporophytic portion of the angiosperm life cycle are also expressed and exposed to selection in the pollen. Given the ha

A simple, non-toxic and effective method to separate germinated from ungerminated pollen grains has been developed using pollen from corn ( Zea mays L. cv. Pioneer 3747). After separation, 99.1% of the grains in the sample of germinated pollen grains

Most sex ratios reported for Silene latifolia are female biased. As a result of experiments performed by Correns in the early 1900s, pollen tube competition has generally been accepted as the primary cause of these skewed ratios. We did four sets of

Pollen competition and variability in pollen fitness can produce non-random fertilization with respect to pollen genotypes, and, owing to the large extent of genetic overlap between the gametophytic and sporophytic phases of the life-cycle, can affec

Marker-assisted selection in backcross breeding is discussed in general and with specific reference to obtaining resistance to chestnut blight in American chestnut (Castaneadentata (Marsh.) Borkh.). Resistance from Chinese chestnut (Castaneamollissim
