Advanced Science, EarlyView.ABSTRACT Viruses often hijack host developmental programs to promote infection, but the mechanistic links between reproductive regulation and antiviral immunity remain incompletely understood. Here, we identify a virus‐triggered hierarchical degradation cascade that links antiviral immunity and fertility regulation in rice. We show that the rice grassy

Pollen physiology and fertilisation in Vicia Faba L [PDF]
, 1990 In many legume crop species, early-formed fruits or those located closest to the photosynthate are more likely to mature than other fruits. This is so in the Vicia faba crop.

Panicle inclination influences pollination stability of rice (Oryza sativa L.)
Plant Production Science, 2020 Rice pollination occurs when pollen grains fall by gravity from the anther onto the stigma and has been thought to be assured under suitable conditions. However, the position of the stigma relative to the anther pores may affect pollination.

American Journal of Agricultural Economics, EarlyView.Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market
