Wear et al. examine replication programs in plants. The Plant Cell 2017. https://doi.org/10.1105/tpc.17.00037 By William Thompson, Emily Wear, and Linda Hanley-Bowdoin DNA replication is fundamental to all life, as it is the process by which genetic material is duplicated so it can be passed from…

Ye et al. discover a gene affecting tomato flavor. The Plant Cell 2017. https://doi.org/10.1105/tpc.17.00211 By Jie Ye Malate—a widely occurring organic acid in plants—is an important contributor to taste. Variation in acid content has a much greater impact on flavor than does the limited…

Zhang et al. investigate protein translation under heat stresss http://www.plantcell.org/content/29/8/1952 By Elizabeth Vierling Plants can’t move to avoid unfavorable growth conditions, such as insufficient water availability or extremes of temperature. When plants are confronted with stressful…

Natural variation in photosynthetic traits can be exploited for new targets for breeding or genetic engineering of crops. In an effort to identify traits which can lead to enhanced biomass production and therefore yield potential in rice, Qu et al. conducted a comprehensive survey of 14 photosynthetic…

The gene FLC (FLOWERING LOCUS C) is a repressor of flowering in Arabidopsis thaliana. It needs to be silenced after exposure to prolonged cold for plants to be able to flower. The memory of winter leads to changes in the methylation state of Histone 3 associated with FLC in two steps: first by recruiting…

Browsing the table of contents of the “The Making of a Plant” special issue of Current Biology feels like a birthday celebration; there are so many exciting goodies it’s hard to know which to open first. The issue consists of well-written and well-illustrated short reviews (and Quick Guides and…

Ion channels are proteins that regulate the passage of ions across membranes. Ion channels are regulated in diverse ways – some are calcium-regulated, some are pH sensitive, some are charge sensitive, and some are sensitive to mechanical stimulation i.e., membrane tension. Basu and Haswell review mechanosensitive…

Leaf size varies by over 100,000-fold across the plant kingdom. Leaf area has a direct impact on tissue temperature and thus directly affects photosynthetic efficiency. Empirical observations by 19th century plant geographers described that larger leaves are usually restricted to plants growing in wet…
