The Green Revolution(GR)of the 1960s saw spectacular increases in cereal crop yields,enabled by widespread adoption of high-yielding semi-dwarf varieties and increased fertilizer ***-dwarfism is caused by mutant wheat Reduced height-1(Rht-1)and rice semi-dwarf1(sd1)alleles,respectively,which confer increased harvest index(grain to straw ratio)and reduced yield loss from“lodging”(flattening of crops by wind or rain).However,despite their obvious global food security benefits,the underlying mechanisms via which GR dwarfing alleles actually work remained *** began to change with the molecular discovery of Rht1(peng et al.,1999).

Unlike most crops,in which soil acidity severely limits productivity,tea(Camellia sinensis)actually prefers acid soils(pH 4.0–5.5).Specifically,tea is very tolerant of acidity-promoted aluminum(Al)toxicity,a major factor that limits the yield of most other crops,and it even requires Al for optimum *** tea Al tolerance and Al-stimulatory mechanisms could therefore be fundamental for the future development of crops adapted to acid ***,we summarize the Al-tolerance mechanisms of tea plants,propose possible mechanistic explanations for the stimulation of tea growth by Al based on recent research,and put forward ideas for future crop breeding for acid soils.

Grain size and shape are prime targets for crop breeders, as they affect both yield and quality of rice. In addition, breeders target plant vegetatNe and reproductive shoot architecture, because these traits influence grain number, and thus yield po- tential. Accordingly, genetic control of grain size and shape as well as shoot architecture has been extensively investigated in recent years. In a recent study, Bin Han and colleagues have used genome-wide association analysis of grain size in a diverse collection of rice varieties of worldwide origin and iden- tified a major quantitative trait locus GLW7, which encodes a SQUAMOSA promoter binding protein-like 13 （OsSpL13）, a member of the plant-specific SBp domain family of transcription factors （Si et al., 2016）. GLW7 positively regulates the size of rice grain cells, thus increasing grain length. GLW7 also regulates rice reproductive shoot （panicle） architecture, and the combined effects of GLW7 on panicle and grain structure increase yield （Si et al., 2016）.
