Improving crop nutrient efficiency can improve agricultural sustainability by increasing yield with lower environmental costs. Here, we summarized the mechanisms and strategies to increase nutrient efficiency, focused on the contributions of root system architecture to acquisition efficiency, as well as mineral translocation, remobilization, and metabolic efficiency to utilization efficiency.

The size and shape of leaves are important factors influencing the success of plants and agricultural productivity. This work identified a mutant locus small and cordate leaf 1 (scl1) that causes the alteration of leaf size and shape in cucumber.

Arabidopsis TOR signaling is essential for sugar-regulated callus formation

Kyounghee Lee and Pil Joon Seo

As an early step of cellular dedifferentiation, tissue explants induce pluripotent cell mass callus. Callus formation involves active cell division and requires sugar signaling. This study demonstrates that sugar supply is essential for robust callus formation, and sugar-dependent callus formation is mainly regulated by TOR-E2Fa module in Arabidopsis.

ARR12 promotes de novo shoot regeneration in Arabidopsis thaliana via activation of WUSCHEL expression

Xuehuan Dai, Zhenhua Liu, Meng Qiao, Juan Li, Shuo Li, and Fengning Xiang

In the arr12 mutant, shoot regeneration was severely impaired and its responsiveness to cytokinin was greatly reduced. ARR12 can directly activate WUS via binding WUS promoter in in vitro culture. Thus ARR12 functions as a link connecting cytokinin signaling with the specification of apical/shoot fate during shoot regeneration.

Localized micronutrient patches induce lateral root foraging and chemotropism in Nicotiana attenuata

We employed field and laboratory assays to determine the capacity of wild tobacco (Nicotiana attenuata) to detect and direct root growth towards localized nutrient patches. Our findings demonstrate that directed root growth underlies foraging behavior, and that chemotropism and micronutrient-guided root placement are important factors shaping root architecture in nature.
